Which type of rock is Most likely to form because of high heat and pressure

The term that refers to the passing of a wave through an object is "transmission."

Transmission refers to the process by which a wave passes through an object or medium. In the context of sound, transmission occurs when sound waves travel through different substances, such as air, water, or solids.

When a sound wave encounters an object, it can be transmitted through it, reflected off it, or absorbed by it, depending on the properties of the object and the medium through which the sound is traveling.

For example, when you speak into a microphone, the sound waves produced by your voice travel through the air and are transmitted to the microphone's diaphragm. The diaphragm converts the sound waves into electrical signals, which can then be amplified and reproduced as sound through speakers.

In summary, transmission is the term used to describe the passage of a wave, such as a sound wave, through an object or medium. It is an essential concept in understanding how waves interact with their surroundings and how sound propagates through different materials.

Answer:

C: 40.

Explanation:

To answer this question, we need to use the concept of heat transfer and the law of conservation of energy, which states that energy cannot be created or destroyed, only transferred or transformed from one form to another.

When two substances are in contact, heat can flow from one substance to another until they reach thermal equilibrium (i.e., they have the same temperature). In this case, Substance 1 loses 40 calories of heat, which means it gives off 40 calories of heat to Substance 2. Therefore, Substance 2 will gain 40 calories of heat to reach thermal equilibrium.

Therefore, the correct answer is option C: 40.

Answer:

Ice melts into liquid water- endothermic

A process with a calculated positive q - endothermic

Wood burns in a fireplace - exothermic

A process with a calculated negative q - exothermic

Acid and base are mixed, making test tube feel hot - exothermic

Solid dissolves into solution, making ice pack feel cold - endothermic

Explanation:

An endothermic process is one in which heat is absorbed from the surroundings. The absorption of heat means that heat is removed from the surroundings hence the surroundings feel cool. When heat is absorbed, q is positive.

An exothermic process is one in which heat is released to the surroundings. The evolution of heat means that heat is released into the surroundings hence the surroundings feel hot . When heat is evolved, q is negative.

Explanation:

Answer:

d

Explanation:

higher no of particles are in CaCl2 solution

The depression in freezing point, elevation in boiling point, etc. are known as colligative particles. Here the CaCl2 solution has the higher boiling point and the NaCl solution has the lower freezing point. The correct option is D.

The properties of a dilute solution which depend only on the number of solute particles present in a given amount of solvent, and not in any way upon the nature of the solute particles are called colligative properties.

The elevation in boiling point is:

ΔTb = i × Kb × m

Here 'i' is the Van't Hoff factor, Kb is constant and 'm' is the molality.

The boiling point depends on the number of ions present in the electrolyte and the concentration. The number of ions in CaCl₂ is 3 whereas the number of ions in NaCl is 2.

ΔTb of CaCl₂ = 3 × 0.25 = 0.75

ΔTb of NaCl = 2 × 0.25 = 0.5

Similarly the freezing point depends on the number of particles of the electrolyte.

So CaCl₂ has boiling point and NaCl has low freezing point.

Thus the correct option is D.

Adam's design for an alarm clock being dependent on batteries is more favorable due to the reliable and consistent power supply, convenience, portability, and the ability to replace or recharge the batteries. Option 3.

Among the given options, Adam's design for the alarm clock being dependent on batteries is more favorable compared to being dependent on sunlight or wind gusts. There are several reasons for this preference.Firstly, batteries provide a reliable and consistent source of power for the alarm clock.

Unlike sunlight, which is only available during the day and can vary depending on weather conditions and location, and wind gusts, which are unpredictable and intermittent, batteries can provide a constant power supply, ensuring that the alarm clock functions consistently and accurately.

Secondly, batteries offer convenience and portability. With a battery-dependent alarm clock, users are not limited by the need for direct exposure to sunlight or reliance on specific weather conditions. They can place the alarm clock anywhere in their room, without worrying about access to natural light or wind.

This portability allows for greater flexibility and convenience in using the alarm clock.

Additionally, batteries can be easily replaced or recharged, ensuring the long-term functionality of the alarm clock. If the batteries run out of power, users can simply replace them or recharge them, allowing the alarm clock to continue functioning without significant interruption.

In contrast, relying on sunlight or wind gusts may result in the clock not being operational when these natural energy sources are unavailable. Option 3 is correct.

Answer:

Claim: The chemical equation presented in the data table does NOT follow the law of conservation of matter

Evidence: Since we initially have 14.25 grams of Na and 9.5 grams of HCl

we will find the number of moles in each, to further apply stoichiometry

So,

Moles of Na: Given mass/Molar Mass = 14.25/23 = 0.62 Moles of Na

Moles of HCl: Given mass/Molar Mass = 9.5/36.5 = 0.26 Moles of HCl

Since HCl is the limiting reagent in this reaction,

0.26 Moles of Na will be consumed, which is equal to

5.98 grams of Na

Reasoning:

We are given that the total mass of the product is 22.98 grams

but through stoichiometry, we have found that only (9.5 + 5.98) = 15.48 grams of product can possibly be formed

Hence, the reaction presented in the table does NOT follow the law of conservation of matter

Explanation:

What?

The mass of the box A is 10 g and the mass of box b is 5 g. The mass ratio between them is:

mass of box a = 10 g

mass of box b = 5 g

mass ratio A/B = mass of box A/mass of box B

mass ratio A/B = 10 g/5 g

mass ratio A/B = 2

The total amount of hydrogen gas generated is 9.76 L, under the condition that 15.9 g of hydrochloric acid reacts with excess zine metal.

Furthermore the balanced chemical equation for the reaction between hydrochloric acid and zinc metal is:
2HCl + Zn → ZnCl₂ + H₂
The molar mass of HCl is 36.46 g/mol.
Then, 15.9 g of HCl is equivalent to 15.9 g / 36.46 g/mol = 0.436 mol of HCl.
As per  the balanced chemical equation, 1 mole of HCl reacts with 1 mole of Zn to produce 1 mole of H₂ gas.
Hence, 0.436 mol of HCl will produce 0.436 mol of H₂ gas.
In Stp (Standard Temperature and Pressure), one mole of any gas occupies 22.4 L.
So, 0.436 mol of H₂ gas will occupy:
0.436 mol × 22.4 L/mol = 9.76 L (approx)
Then, approximately 9.76 L of hydrogen gas will be produced when 15.9 g of hydrochloric acid reacts with excess zinc metal at STP.

Hello there!

In this case, since this imaginary gas can be modelled as an ideal gas, we can write:

\(PV=nRT\)

Which can be written in terms of density and molar mass as shown below:

\(\frac{P}{RT} =\frac{n}{V} \\\\\frac{P}{RT} =\frac{m}{MM*V}\\\\\frac{P*MM}{RT} =\frac{m}{V}=\rho\)

The concentration of H₂SO₄ solution is equal to 0.0480 M.

A neutralization reaction is described as a chemical reaction where acid and base react to produce respective salt and water. When a strong acid reacts with a strong base then the salt can be neutral.

When H₂SO₄ (a strong acid) reacts with NaOH, the resulting salt is Na₂SO₃  and water.

H₂SO₄  +  2 NaOH   →   Na₂SO₄  +   2H₂O

Given, the concentration of NaOH = 0.146 M

The volume of the NaOH = 14.85 ml = 0.01485 L

The number of moles of NaOH, n = M × V = 0.146 × 0.01485 = 0.00216 M

The volume of the  H₂SO₄ = 22.55 ml = 0.02255 L

The number of moles of  H₂SO₄, n = 0.00216/2 = 0.00108 mol

There are approximately \(2.76 * 10^{24\) ammonia molecules in the given sample.

To calculate the number of ammonia molecules in the sample, we need to use Avogadro's number and the molar mass of ammonia.

The molar mass of ammonia \((NH_3)\) can be calculated by adding up the atomic masses of nitrogen (N) and hydrogen (H):

Molar mass of \(NH_3\) = (1 x atomic mass of N) + (3 x atomic mass of H)

              = (1 x 14.01 g/mol) + (3 x 1.01 g/mol)

              = 14.01 g/mol + 3.03 g/mol

              = 17.04 g/mol

Now, we can calculate the number of moles of ammonia in the sample using the formula:

Number of moles = Mass of the sample / Molar mass

Number of moles = 78.25 g / 17.04 g/mol

              ≈ 4.5865 mol (rounded to four decimal places)

Finally, we can use Avogadro's number, which represents the number of particles (atoms, molecules, etc.) in one mole of a substance. Avogadro's number is approximately \(6.022 * 10^{23\) particles/mol.

Number of ammonia molecules = Number of moles x Avogadro's number

Number of ammonia molecules ≈ 4.5865 mol x (\(6.022 * 10^{23\) molecules/mol)

                           ≈ \(2.76 * 10^{24\) molecules (rounded to two significant figures)

Therefore, the provided sample contains roughly \(2.76 * 10^{24\) ammonia molecules.

The number of ammonia molecules in the sample is approximately 2.764 x \(10^{24}\) molecules.

To calculate the number of ammonia molecules in a given sample, we need to use Avogadro's number and the molar mass of ammonia.

The molar mass of ammonia (NH3) is calculated as follows:

Molar mass of N = 14.01 g/mol

Molar mass of H = 1.01 g/mol

Total molar mass of NH3 = 14.01 g/mol + (3 * 1.01 g/mol) = 17.03 g/mol

Now, we can calculate the number of moles of ammonia in the sample:

Number of moles = Mass of sample / Molar mass of NH3

Number of moles = 78.25 g / 17.03 g/mol = 4.594 moles

Next, we use Avogadro's number, which states that there are 6.022 x \(10^{23}\) molecules in one mole of a substance.

Number of molecules = Number of moles * Avogadro's number

Number of molecules = 4.594 moles * 6.022 x \(10^{23}\) molecules/mol = 2.764 x \(10^{24}\) molecules

Therefore, there are approximately 2.764 x \(10^{24}\) ammonia molecules in the given sample of 78.25 g.
