Boiling water or any other liquid is considered a physical change even though it might evaporate into a gas. This is because nothing is being done chemically to change it.

Water can be made using the reversible reaction shown. Which change would
Ghella [55]

Decreasing the temperature in the reaction vessel keep this reaction from shifting to form more of the product.

As we know that rate of reaction is directly proportional to the concentration of the reactant.

If we increase the concentration of H2 then the rate of reaction increases. So, we keep it constant. Therefore this option is wrong.

By removing the H₂O from the reaction vessel as it almost make no change in the reaction. This can be pursuited the reaction in which product again converted into product.

By increasing the temperature we increases the rate of reaction and equilibrium shift in the forward direction.

Thus, we concluded that by decreasing the temperature in the reaction vessel keep this reaction from shifting to form more of the product.

How is a pure substance different from a mixture?
Sauron [17]
The answer is A.
Pure substance is either an element or a compound, which elements in compund is chemically combined together. They cannot be separated by physical methods such as filtration or evaporation. Compounds can only be separated by chemical methods, which include using electricity (electrolysis) or applying heat.

In the reaction H2CO3 (aq) + 2NH3 (aq) = 2NH4^+ (aq) + CO3 2- (aq), how many electrons are transferred?
aalyn [17]

The electrons are transferred when the reaction is redox reaction. It means that there must be reduction and oxidation.

The given equation is

H_{2}CO_{3} (aq)+2NH_{3} (aq)=2NH_{4}^{+}(aq)+CO_{3}^{-2}(aq)

The oxidation number of each element remains the same before and after the reaction.

H = +1

C: +4

O: -2

N: -3

Thus this is simple acid base reaction and not redox

There is transfer of proton from bicarbonate to ammonia

this is not a redox reaction
