The refrigerator would use 180 kilowatt-hours (kWh) of electric energy over the course of 30 days, assuming it runs for 12 hours each day.

To calculate the kilowatt-hours (kWh) of electric energy used by the refrigerator in 30 days, we need to multiply the power rating by the total running time.

Given:

Power rating of the refrigerator = 500 W

Running time per day = 12 hours

Number of days = 30

First, we need to convert the power rating from watts to kilowatts:

Power rating = 500 W / 1000 = 0.5 kW

Next, we calculate the total energy used in kilowatt-hours (kWh) over the 30-day period:

Energy used = Power rating × Running time × Number of days

Energy used = 0.5 kW × 12 hours/day × 30 days

Energy used = 180 kWh

Therefore, the refrigerator would use 180 kilowatt-hours (kWh) of electric energy over the course of 30 days, assuming it runs for 12 hours each day.

Answer:

The density is the mass per unit volume of a substance.

Density is important when working out if something will float in water, and it can also be useful for calculating the mass of a specific volume of a substance.

Explanation:

Question 1. There are \(9.025*10^{23}\) molecules in 270g of glucose.

Question 2. There are \(3.009*10^{23}\) molecules in 40g of glucose.

Formula: \(C_{6} H_{12} O_{6}\)

Using the molar mass of each element, which can be found in the periodic table, we make the following calculations:

Molar mass of C: 12.011 u

Total mass of C in compound: (12.011 * 6)= 72.066

Molar mass of H: 1.008 u

Total mass of H in compound: (1.008 * 12)= 12.096

Molar mass of O: 15.999 u

Total mass of O in compound: (15.999 * 6)= 95.994

Why did we multiply the molar mass of C, H and O by 6, 12, and 6? This is because the formula contains 6, 12, and 6 atoms of each element, respectively.

Add up all masses:

72.066 + 12.096 + 95.994= 180.156 g/mole

This result means that 1 mole of glucose has a mass of 180.156 grams.

Furthermore, 1 mole of any compound has a total of \(6.022*10^{23}\) molecules. To find the amount of molecules, find the amount of moles and then the amount of molecules. Do it in the following fashion:

180.156g  -----> 1 mole

270g -----------> x

\(\frac{270*1}{180.156} =1.499\)

270 grams of glucose is the equivalent of 1.499 moles of said compound.

Now, find the number of molecules using the amount of moles calculated previously.

180.156g ----> \(6.022*10^{23}\)

270g ---------> x

\(\frac{(270*6.022*10^{23} )}{180.156} =9.025*10^{23}\)

There are \(9.025*10^{23}\) molecules in 270g of glucose.

\(NH_{4} NO_{3}\)

N: 14.007 u

N: 14.007 u

O: (15.999 * 3)= 47.997 u

14.007 + 4.032 + 14.007 + 47.997= 80.043 g/mole

80.043g ----> \(6.022*10^{23}\)

40g -----------> x

\(x=\frac{(40*6.022*10^{23}) }{80.043} =3.009*10^{23}\)

There are \(3.009*10^{23}\) molecules in 40g of glucose.

A total of 1909 grams of sodium are in 5. 0 x 10²⁵ atoms of sodium

The moles of a substance are given as,

Moles = Mass/Molar mass

Molar mass of sodium is 23 g/mol. We also know that the moles are given as the number of entities divided by Avogadro number.

The atoms of sodium are 5.0 x 10²⁵. The Avogadro number is 6.02 × 10²³

Moles = Number of entity/Avogadro number

So, it should be right to write,

Mass/Molar mass = Number of entity/Avogadro number

Putting all the values,

5.0 x 10²⁵/6.02 x 10²³ = Mass/23

0.83 x 10² = Mass/23

The molar mass of CaCl2 is 110.98 g/mol. So, 1200.0 g of CaCl2 is equal to 1200.0 / 110.98 = 10.88 moles of CaCl2.

A 1.5 M CaCl2 solution contains 1.5 moles of CaCl2 per liter of solution. So, 10.88 moles of CaCl2 can be dissolved in 10.88 / 1.5 = 7.2 liters of solution.

Therefore, 7.2 liters of 1.5 M CaCl2 solution can be made using 1200.0 g of CaCl2.

Here is the solution in equation form:

```

Molarity = moles / volume

1.5 M = 10.88 moles / volume

volume = 10.88 moles / 1.5 M

volume = 7.2 liters

```

Approximately 7.21 liters of a 1.5 M CaCl₂ solution can be made using 1200.0 g of CaCl₂.

To calculate the volume of a 1.5 M CaCl₂ solution that can be made using 1200.0 g of CaCl₂, you need to follow these steps:

Determine the molar mass of CaCl₂: Calcium (Ca) has an atomic mass of 40.08 g/mol, and chlorine (Cl) has an atomic mass of 35.45 g/mol. Since CaCl₂ consists of one calcium atom and two chlorine atoms, the molar mass of CaCl₂ is calculated as follows:

Molar mass of CaCl₂ = (1 * atomic mass of Ca) + (2 * atomic mass of Cl)

= (1 * 40.08 g/mol) + (2 * 35.45 g/mol)

= 40.08 g/mol + 70.90 g/mol

= 110.98 g/mol

Calculate the number of moles of CaCl₂: Divide the given mass of CaCl₂ (1200.0 g) by its molar mass (110.98 g/mol):

Moles of CaCl₂ = Mass of CaCl₂ / Molar mass of CaCl₂

= 1200.0 g / 110.98 g/mol

≈ 10.81 mol

Calculate the volume of the solution: The concentration of the solution is given as 1.5 M, which means there are 1.5 moles of CaCl₂ per liter of solution. You can use the following formula to calculate the volume of the solution:

Volume (in liters) = Moles of solute / Concentration

= 10.81 mol / 1.5 mol/L

≈ 7.21 L

A. 257600g (i.e 257.6 Kg) of CaO were produced.

B. 202400g (i.e 202.4 Kg) of CO2 were produced.

Explanation:

We'll begin by calculating the mass of CaCO3 present in 5×10² Kg of lime stone. This is illustrated below:

From the question given, the lime stone contains 92% of CaCO3.

Mass of CaCO3 = 92% x 5×10² Kg

Mass of CaCO3 = 92/100 x 5×10² Kg

Mass of CaCO3 = 460 Kg

Therefore, 460 kg of CaCO3 is present in the lime stone.

Next, we shall determine the mass of CaCO3 that was heated and the masses of CaO and CO2 produced from the balanced equation. This is illustrated below:

CaCO3(s) —> CaO(s) + CO2(g)

Molar mass of CaCO3 = 40 + 12 + (16x3) = 100g/mol

Mass of CaCO3 from the balanced equation = 1 x 100 = 100g

Molar mass of CaO = 40 + 16 = 56g

Mass of CaO from the balanced equation = 1 x 56 = 56g

Molar mass of CO2 = 12 + (2x16) = 44g/mol

Mass of CO2 from the balanced equation = 1 x 44 = 44g

Summary:

From the balanced equation above,

100g of CaCO3 were heated to produce 56g of CaO and 44g of CO2.

A. Determination of the mass of quick lime, CaO produced by heating 5×10² Kg of lime stone.

5×10² Kg of lime stone contains 460 Kg (i.e 460×10³ g) of CaCO3.

From the balanced equation above,

100g of CaCO3 were heated to produce 56g of CaO.

Therefore, 460×10³g of CaCO3 will be heated to produce = (460×10³ x 56)/100 = 257600g of CaO.

Therefore, 257600g (i.e 257.6 Kg) of CaO were produced.

B. Determination of mass of carbon dioxide, CO2 produced by heating 5×10² Kg of lime stone.

5×10² Kg of lime stone contains 460 Kg (i.e 460×10³ g) of CaCO3.

From the balanced equation above,

100g of CaCO3 were heated to produce 44g of CO2.

Therefore, Therefore, 460×10³g of CaCO3 will be heated to produce = (460×10³ x 44)/100 = 202400g of CO2.

Therefore, 202400g (i.e 202.4 Kg) of CO2 produced.

The concentration of volatile suspended solids (Xv) in the lagoon to assess the effluent quality. However, the specific aerator capacity needed cannot be determined without additional information or equations.

To determine if the industry will likely meet the desired effluent quality, we can calculate the BODL concentration in the aerated lagoon and the concentration of volatile suspended solids (Xv) in the lagoon.

BODL concentration in the aerated lagoon:

The BODL concentration in the lagoon can be calculated using the equation:

BODL_lagoon = BODL_influent - q * Xv * θ

where BODL_influent is the initial BODL concentration (2,000 mg/l), q is the specific oxygen utilization rate (27 mgBODL/mgVSSa-d), Xv is the concentration of volatile suspended solids (to be determined), and θ is the hydraulic retention time (1 day).

Concentration of volatile suspended solids (Xv) in the lagoon:

The concentration of volatile suspended solids can be calculated using the equation:

Xv = BODL_influent / (q * θ)

where BODL_influent is the initial BODL concentration (2,000 mg/l), q is the specific oxygen utilization rate (27 mgBODL/mgVSSa-d), and θ is the hydraulic retention time (1 day).

By substituting the given values into the equations, we can calculate the BODL concentration in the lagoon and the concentration of volatile suspended solids.

Regarding the aerator capacity needed, the question asks for the amount of aerator capacity in kW/1,000 m3 of tank volume. To calculate this, we need the field oxygen transfer efficiency (1 kgO2/kWh). However, the equation or method to determine the aerator capacity based on the given information is not provided. Without additional information or equations, it is not possible to calculate the specific aerator capacity needed in this scenario.

When equal masses of silver and platinum are transferred to equal volumes of water, the cylinder with platinum will show the greatest volume change. This is because platinum has a higher density than silver, resulting in a larger volume displacement.

To determine which cylinder would show the greatest volume change when equal masses of silver and platinum are transferred to equal volumes of water, we can compare their densities.

Density is defined as mass per unit volume. Therefore, the ratio of mass to volume can be used to compare the relative volume changes for the two substances.

Transfer the same mass (m) of silver and platinum to equal volumes of water.

For silver:

Density of silver = 10.5 g/mL

Mass of silver = m

Volume of silver = (Mass of silver) / (Density of silver) = m / 10.5

For platinum:

Density of platinum = 21.45 g/mL

Mass of platinum = m

Volume of platinum = (Mass of platinum) / (Density of platinum) = m / 21.45

Comparing the volume changes:

Volume change for silver = Volume of silver - Volume of water = (m / 10.5) - (Volume of water)

Volume change for platinum = Volume of platinum - Volume of water = (m / 21.45) - (Volume of water)

The volumes of water are equal in both cases, we can ignore them for the comparison.

Therefore, the ratio of the volume change for silver to the volume change for platinum is:

(Volume change for silver) / (Volume change for platinum) = [(m / 10.5) - (Volume of water)] / [(m / 21.45) - (Volume of water)]

Since the volume of water is the same in both cases, it cancels out from the equation.

Thus, the ratio simplifies to:

(Volume change for silver) / (Volume change for platinum) = (m / 10.5) / (m / 21.45) = (21.45 / 10.5)

Therefore, the volume change for platinum is greater than the volume change for silver, as the ratio of their densities is greater than 1.

In conclusion, when equal masses of silver and platinum are transferred to equal volumes of water, the cylinder with platinum would show the greatest volume change.

Carbon (C)

Explanation:

Because the element is the element of the main subgroup of group IV , it has oxidation number +4 in the oxide, and oxide formula is EO2.

reaction:

                                     EO2 + H2O ---> H2EO3

from reaction               1 mol    1 mol       1 mol

31 g acid - 22 g oxide = 9 g water

M(H2O) = 18 g/mol

9g * 1 mol/18 g = 0.5 mol H2O

As we see from reaction molar ratios EO2 : H2O : H2EO3 = 1 : 1 : 1,

so if  we have 0.5 mol H2O , we also have 0.5 mol EO2.

0.5 mol EO2 has mass 22 g.

Molar mass(EO2) = mass/ number of moles = 22 g/ 0.5 mol = 44 g/mol

Molar mass (EO2) = M(E) + 2M(O) = 44 g/mol

M(E) + 2 *16 g/mol = 44 g/mo

M(E) = 44-32 = 12 g/mol

Molar mass 12 g/ mol is molar mass of carbon.

So, element is carbon (C).
