Answer: The reaction that occurs at anode is \(Zn(s)\rightarrow Zn^{2+}(aq.)+2e^-\)

Explanation:

Given : \(E^o_{Zn^{2+}/Zn}=-0.76V\)

\(E^o_{Cu^{2+}/Cu}=+0.34V\)

The substance having highest positive reduction potential will always get reduced and will undergo reduction reaction. Here, copper will undergo reduction reaction will get reduced.

The substance having highest negative reduction potential will always get oxidised and will undergo oxidation reaction. Here, zinc will undergo oxidation reaction will get oxidised.

Oxidation reaction occurs at anode and reduction reaction occurs at cathode.

Oxidation half reaction (anode) : \(Zn(s)\rightarrow Zn^{2+}(aq.)+2e^-\)

Reduction half reaction (cathode) : \(Cu^{2+}(aq.)+2e^-\rightarrow Cu(s)\)

The alkane with the molecular formula C10H16 has one ring. This ring structure reduces the number of hydrogen atoms by two compared to the corresponding straight-chain alkane.

To determine the number of rings in an alkane with the formula C10H16, we can compare it to the corresponding straight-chain alkane, which would be C10H22. Since the alkane C10H16 has 2 fewer hydrogen atoms than its straight-chain counterpart, it suggests the presence of one ring in the molecule.

The molecular formula of an alkane provides information about the number of carbon and hydrogen atoms in its structure. In the given formula C10H16, the presence of 10 carbon atoms indicates that it forms a chain of carbon atoms. However, since it has 16 hydrogen atoms, which is 2 fewer than the maximum number of hydrogen atoms possible for a straight-chain alkane with 10 carbon atoms, there must be a structural deviation. The deviation in the number of hydrogen atoms suggests the formation of one ring in the molecule. Each carbon atom in the ring contributes two hydrogen atoms, whereas in a straight-chain alkane, each carbon atom is bonded to three hydrogen atoms. By forming a ring, two of the carbon atoms in the chain lose one hydrogen atom each, resulting in a net loss of two hydrogen atoms.

Therefore, the alkane with the molecular formula C10H16 has one ring. This ring structure reduces the number of hydrogen atoms by two compared to the corresponding straight-chain alkane. It is important to note that the specific arrangement of the carbon atoms in the ring and their connectivity would determine the isomeric form of the molecule.

In ammonia, the nitrogen shares 3 of its valence electrons with each hydrogen atom and each of the hydrogen atom shares one valence electron. So option a is right.

Nitrogen has 5 electrons in its outer shell and hydrogen has one electron. All atoms try to complete octet electronic configuration to become stable. So covalent compound forms covalent bonds by sharing the electrons. Here one nitrogen forms covalent bonds with three hydrogen atoms by sharing one electron with each.

As there is 5 electrons in the outer shell, two of them remains as lone pair of electrons. Here since only one pair of electrons are shared between atoms, they form single bond with each other.

So nitrogen shares 3 electrons and each hydrogen contributes one.

The upthrust keeps a ship afloat. The upthrust keeps swimmers on top of the water. Things weigh less in water.

The upward force exerted on a body by the fluid in which the body is submerged is called the upthrust or buoyant force. The property of liquid to exert an upward force on a body immersed in it is called buoyancy. Being a force upthrust is measured in newton or kgf in the system of international units. Examples Pushing an empty can into water experiences the buoyant force. Pushing a cork into water into water experiences the buoyant force. Reason for Upthrust The thrust ating on on the sides of walls of the body get neutralised because they are equal in magnitude and opposite in the directions. There is a pressure difference between the lower and upper faces of block. Since force is the product of pressure and area, The difference in pressure due to liquid is on th two faces of causes a net upward force called upthrust on the body immersed in the fluid.

Answer: upthrust an upward force exerted by a fluid that opposes the weight of an immersed object.It is the force that pushes an object up. ... the upward force that a liquid or gas exerts on a body floating in it.

When a body is placed in water, Up thrust = V x d x g

From the above formula we can say that the following are the factors that affect up thrust:

Acceleration due to gravity - (g)

Density of the liquid - (d)

Volume of the body submerged in the liquid - (V), or volume of the liquid displaced (v)

The least likely element combination would be hydrogen (H) and sodium (Na) since their ionization energies differ significantly.

To determine the least likely element combination, we need to consider the ionization energies and their relative values. The element combination that is least likely would involve elements with similar or close ionization energies.

Comparing the ionization energies:

1,312 kJ/mol (H) < 1,402 kJ/mol (N) < 1,314 kJ/mol (O) < 496 kJ/mol (Na)

Based on these values, the least likely element combination would be hydrogen (H) and sodium (Na) since their ionization energies differ significantly.

Explanation:

This is a joke, please don't take this seriously.

A- The order is to administer Streptomycin 0.25g.

b. The available is a vial of Streptomycin powder, which can be reconstituted with 9 mL of sterile water to obtain a concentration of 400 mg/2 mL.

c. The patient will be administered a volume of 1.25 mL of the reconstituted Streptomycin solution.

To calculate the volume to be administered, we first convert the ordered dosage from grams to milligrams: 0.25g = 250mg.

Next, we use the concentration of the reconstituted solution, which is 400 mg/2 mL. This means that 2 mL of the solution contains 400 mg of Streptomycin. We set up a proportion to find the volume (X mL) that contains the required 250 mg:

400 mg / 2 mL = 250 mg / X mL

Cross-multiplying and solving for X, we get:

400 mg * X mL = 2 mL * 250 mg

X = (2 * 250) / 400 = 500 / 400 = 1.25 mL

To calculate the percentage of global mismanaged plastic that comes from the US, we can follow these steps:

Step 1: Convert the US contribution from tons per month to tons per year.

US contribution = 0.022 million tons per month * 12 months = 0.264 million tons per year

Step 2: Calculate the percentage.

Percentage = (US contribution / Global mismanaged plastic) * 100

Percentage = (0.264 million tons per year / 31.9 million tons per year) * 100

Calculating this expression gives:

Percentage = 0.828 %

Therefore, the US contributes approximately 0.828% of the global mismanaged plastic.

If the sample of magnesium used in a lab was contaminated with another metal that doesn't react with hydrochloric acid, then the results obtained in the experiment would be affected.

This is because the data collected during the experiment would reflect the reaction between hydrochloric acid and the contaminated sample instead of pure magnesium. As a result, the following changes in results might have been observed:

1. The mass of the contaminated sample would be higher than the mass of pure magnesium.

2. The rate of reaction between the contaminated sample and hydrochloric acid would be slower than the reaction between pure magnesium and hydrochloric acid.

3. The volume of hydrogen gas collected from the reaction would be lower than the volume of hydrogen gas collected in the reaction between pure magnesium and hydrochloric acid.

At the same temperature, the gas has a 2.5 L volume at 7.0 atm. Volume in the context of gases is the quantity of space a gas takes up.

The ideal gas law, which connects a gas's pressure, volume, and temperature, can be used to solve this issue. PV = nRT. Assuming that the temperature stays constant, we may apply the ideal gas law in the following manner: P1V1 = P2V2. With the supplied values plugged in, we obtain (5.0 atm)(3.5 L) = (7.0 atm) (V2). We can calculate V2 as follows: V2 = (5.0 atm)(3.5 L) / (7.0 atm) = 2.5 L. As a result, the gas has a 2.5 L volume at the same temperature at 7.0 atm. In many industrial, scientific, and medical applications, accurate gas volume measurement and management are crucial.

The yield of Cu(OH)2 is equal to the amount of CuCl2 used.

Yield is a quantitative measure of the amount of product obtained from a reaction. It is usually expressed as a percentage of the theoretical yield, which is the maximum amount of product that could be obtained from the given amounts of reaction components. Yield is an important concept in chemistry because it provides a means for evaluating the efficiency of the reaction, the quality of the conditions and the effectiveness of the purification process. Yield can be determined by measuring the amount of product obtained following a reaction, then dividing that amount by the theoretical yield. This calculation provides an estimate of how much of the desired product was obtained from the reaction.

The yield of Cu(OH)2 using CuCl2 is determined by the mole ratio of the two reactants. The balanced equation for the reaction is:
CuCl2 + 2NaOH → Cu(OH)2 + 2NaCl
The mole ratio of CuCl2 to Cu(OH)2 is 1:1, so for every mole of CuCl2 used, one mole of Cu(OH)2 is produced. Therefore, the yield of Cu(OH)2 is equal to the amount of CuCl2 used.
