You carefully weigh out 16.00 g of CaCO3 powder and add it to 64.80 g of HCl solution. You notice bubbles as a reaction takes pl
bulgar [2K]

Answer: Mass of CO_2  produced in this reaction was 6.56 grams

Explanation:

According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.

CaCO_3(s)+2HCl(aq)\rightarrow H_2O(l)+CO_2(g)+CaCl_2(aq)

Mass or reactants =  Mass of CaCO_3+ mass of HCl = 16.00 + 64.80 = 80.80 g

Mass of products  = mass of aqueous solution + mass of CO_2 + = 74.24 + x g

Mass or reactants = Mass of products

80.80 g = 74.24 + x g

x = 6.56 g

Thus mass of CO_2  produced in this reaction was 6.56 grams

Electrolytic cells use electricity to cause a nonspontaneous redox reaction to occur. An electrolytic cell is constructed using
Fittoniya [83]

Answer:

At anode - {Br_2}_{(l)}

At cathode - {H_2}_{(g)}

Explanation:

Electrolysis of NaBr:

Water will exist as:

H_2O\rightleftharpoons H^++OH^-

The salt, NaBr will dissociate as:

NaBr\rightarrow Na^++Br^-

At the anode, oxidation takes place, as shown below.

{Br^-}_{(aq)}\rightarrow {Br_2}_{(l)}+2e^-

At the cathode, reduction takes place, as shown below.

2{H^+}_{(aq)}+2e^-\rightarrow {H_2}_{(g)}
