URGENT!!!
Ksenya-84 [330]

Answer: The balance of the reaction shifts toward the endothermic reaction.

Explanation:

An ENDOTHERMIC REACTION requires input of HEAT ENERGY to drive it FORWARD from reactants, unto completion of products.

So, on increasing the temperature (available heat) the REVERSIBLE REACTION favors the shifts towards the endothermic reaction

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

• Reflect on the importance of stoichiometry and rate of chemical reaction in the design of car airbags
PSYCHO15rus [73]

Answer:

If an insufficient amount of nitrogen were produced, the air bag would under inflate and not provide adequate protection. Clearly, the stoichiometry of the reaction is very important.
