Answer:

Due its storing and holding ability.

Explanation:

It matter that the material from which the vat is made is metal because this vat is used for storing and holding liquids. Vat is a large container or tank that is used for storing or holding liquids in industrial sector. This vat is made of metal which increases its strength and durability. If the vat is made of wood or plastic so it can't hold huge amount of liquid or chemical due to its weak material so that's why it matters that the substance from which the vat is made is metal or not.

The question is incomplete, the complete question is;

1. Given: 2A(g) <-> 2B(g) + C(g). At a particular temperature, K = 1.6x104.

At a higher temperature, K = 1.8x10-5. Placing the equilibrium mixture in an ice bath (thus lowering the temperature) will...

cause [A] to increase

cause [B] to increase

gave no effect

cannot be determined

Answer:

cause [B] to increase

Explanation:

We have to have it behind our minds that;  for an exothermic reaction, when the temperature is increased, the value of the equilibrium constant decreases. On the other hand, for an endothermic reaction, increasing the temperature increases the value of the equilibrium constant.

In this particular case, increasing the temperature decreased the equilibrium constant from K = 1.6x104 to K = 1.8x10-5 meaning that the equilibrium constant decreased with increase in temperature. This means that the reaction is exothermic and a decrease in temperature will favour the forward reaction hence more B is produced.

Answer:

If a material gains electrons, its going to be Negatively charged

If a material loses electrons, its gonna be positively charged.

Explanation:

Why?

This is because electrons are negative subatomic particles

Answer:

Because carbohydrates are energy

Explanation:

Carbohydrates is best best nutrient for energy, turning into energy as soon as they are eaten. A rickshaw puller most likely needs quite a bit of energy to pedal all day without getting tired, so that's why they eat a carbohydrate rich diet.

Answer:

Mg⁺² = 0.525 mol/L

Cl⁻ = 1.05 mol/L

Explanation:

The formula for magnesium chloride is MgCl₂, and in a solution the following process takes place:

By analyzing the stoichiometric coefficients, we can tell that the concentration of Mg⁺² ions is the same as the concentration of MgCl₂, while the Cl⁻ concentration is twice that value.

A possible solution for maximizing the percentage of hydrogen in discarded wood is to design a machine that can collect more effectively all the gases and separate hydrogen from other gases.

Discarded wood and other products can still produce important elements nitrogen, methane, and hydrogen. This is possible through combustion that releases these elements in a gas.

This is a new method and it is still not completely developed. Due to this, the equipment is not as efficient as one would like, for example, all gases are initially collected together but this is a problem if only one gas is needed.

Based on this, a potential solution would be to create a machine that is more efficient in collecting and separating the gases.

Answer: A

Explanation:

5.0 g / 56 g/mol is the numerical expression that gives the number of moles in 5.0 g of CaO.

HOW TO FIND NUMBER OF MOLES:

CaO = 40g/mol + 16g/mol = 56g/mol

Number of moles = 5.0g ÷ 56g/mol

Therefore, 5.0 g / 56 g/mol is the numerical expression that gives the number of moles in 5.0 g of CaO.

Answer: A heat energy of 50160 joules are required to heat 15 grams of ice from [tex]-200^{o}C[/tex] to [tex]1400^{o}C[/tex].

Explanation:

Given : mass of ice = 15 g

Convert grams into kg as follows,

[tex]1 g = 0.001 kg\\15 g = 15 g \times \frac{0.001 kg}{1 g}\\= 0.015 kg[/tex]

Initial temperature = [tex]-200^{o}C[/tex]

Final temperature = [tex]1400^{o}C[/tex]

Formula used to calculate the amount of heat energy is as follows.

[tex]q = m \times C \times (T_{2} - T_{1})[/tex]

where,

q = heat energy

m = mass of substance

C = specific heat of substance (ice here has C = [tex]2090 J/kg ^{o}C[/tex])

[tex]T_{1}[/tex] = initial temperature

[tex]T_{2}[/tex] = final temperature

Substitute the values into above formula as follows.

[tex]q = m \times C \times (T_{2} - T_{1})\\= 0.015 kg \times 2090 J/kg^{o}C \times [1400 - (-200)]^{o}C\\= 50160 J[/tex]

Thus, we can conclude that 50160 joules are required to heat 15 grams of ice from [tex]-200^{o}C[/tex] to [tex]1400^{o}C[/tex].
