The time to plate out 10.0 g of zinc using a current of 5.0 A is 98.35 minutes.

The reduction reaction in the electrolysis reaction of zinc

Zn²⁺ + 2e → Zn.

Based on stoichiometry, the number of moles is proportional to the number of reacting atoms or ions.

Number of moles for Zn
n = m ÷ Mr

n = 10.0 ÷ 65.4 = 0.153 mol

Number of moles for electrons
n Zn : n e = 1 : 2
n e = 2 × n Zn
n e = 2 × 0.153 = 0.306 mol

The equation for the number of moles of an electron from Faraday's law
n e = It ÷ 96,485

It = n e × 96,485

5.0 × t = 0.306 × 96,485

t = 29,506.12 ÷ 5

t = 5,901.22 s

t = 5,901.22 ÷ 60 minutes

The number of moles of sulfuric acid in the solution would be 0.005 mol.

First, the balanced equation of the reaction is as below:

[tex]H_2SO_4 + 2NaOH -- > Na_2SO_4 + 2H_2O[/tex]

From the equation, the mole ratio of sodium hydroxide to sulfuric acid is 2:1. This means that for every 1 mole of sodium hydroxide used in the reaction, 0.5 moles of sulfuric acid is required.

Now, in this case, the indicator changed color after 0.01 mol of sodium hydroxide has been added to the sulfuric acid solution. This means that the reaction has been completed.

With 0.01 mol of sodium hydroxide used, the equivalent mole of sulfuric acid would be:

0.01/2 = 0.005 mol.

In other words, the number of moles of sulfuric acid in the solution would be 0.005 mol.

Answer:

Apple trees bloom in the spring because they require a certain amount of cold weather, known as chill hours, in order to break dormancy and produce flowers. In most regions where apple trees grow, the temperatures during the springtime provide the ideal conditions for the trees to bloom. During the summer, apple trees are focused on growing and ripening their fruit, rather than producing flowers. In some cases, apple trees may produce a small number of flowers during the summer, but this is not the norm. The exact amount of chill hours that apple trees need can vary depending on the specific variety of apple tree, as well as the region where it is grown.

Explanation:

Answer:

Drought may trigger out-of-season blooming

Many trees and shrubs that flower in early spring, like apples and lilacs, form their buds during the preceding summer. When spring breaks the plant's dormancy, the buds burst open and bloom.

The concentration terms are molality, normality and mole fraction. Molarity can be used to find out the ionic strength of any solution. Therefore, 0.020M is the [OH⁻] in a solution that contains 0.285 g of NaOH in 0.350 L of solution.

Molarity can be calculated by dividing number of moles of solute by volume of solution in litre. Molarity is affected by temperature. Its unit is mole/liter. It measure the concentration of any solute in a solution.

Mathematically,

Molarity= number of moles of solute/volume of solution in litre

Where,

moles= given weight /by molecular weight

         = 0.285 g/ 40

         =0.0071moles

Substituting values in equation 1

Molarity=0.0071/0.350

Molarity=0.020M

Therefore, 0.020M is the [OH⁻] in a solution that contains 0.285 g of NaOH in 0.350 L of solution.

Explanation:

I hope this helps and have a wonderful day!

According to the reaction, the one mole or 28 g of CO produces one mole or 32 g of methanol. Thus, 16.7 g will produce 19 g of methanol.

Methanol is an organic compound formed by the covalent bonding between carbon and oxygen. Methanol is the basic alcohol.

As per the balanced reaction CO be the limiting reactant. One mole of CO produces one mole of methanol.

molar mass of CO = 28 g/mol

molar mass of methanol = 32 g/mol

28 g of CO produces 32 g of methanol. Hence, mass of methanol produced by 16.7 g of CO is:

= (16.7g × 32 g) / 28 g.

= 19 g.

Therefore, the mass of methanol produced from 16.7 g will be 19 g.

Yes, this is correct. When an electron moves closer to the nucleus, the electrical attraction between the electron and the nucleus increases and the electron must expend more energy to stay in that position. This increase in energy is due to the increased force of attraction between the electron and the nucleus.

The interaction between electrons and the nuclei of atoms is the basis of chemistry. This interaction is due to the attractive force of electric charge, which is known as electrostatic attraction. This force can be felt when an electrically charged object approaches another electrically charged object.

The electrostatic attraction between an electron and the nucleus of an atom depends on the electric charge and the distance between them. The more charged the electron is, the stronger the attraction. The closer the electron is to the nucleus, the stronger the attraction.

This means that when an electron moves toward the nucleus, the electrostatic attraction between them increases, requiring the electron to expend more energy to stay there. This means that when an electron moves closer to the nucleus, the energy of the electron increases to overcome the positive and negative attraction.
