pav-90 [236]

Answer:

The answer to your question is: 17.26% of carbon

Explanation:

Data

CxHy = 0.2121 g

BaCO₃ = 0.6006 g

Molecular mass BaCO₃ = 137 + 12 + 48 = 197 g

Reaction

                    CO₂  +  Ba(OH)₂  ⇒   BaCO₃  +  H₂O

Process

1.- Find the amount of carbon in BaCO₃

                              197 g of BaCO₃   ---------------  12 g of Carbon

                               0.6006 g           ----------------    x

                               x = (0.6006 x 12) / 197

                               x = 0.0366 g of carbon

2.- Calculate the percentage of carbon in the organic compound

           0.2121 g of organic compound  ---------------  100%

           0.0366g                                       --------------    x

                              x = (0.0366 x 100) / 0.2121

                              x = 17.26%

Which of the following compounds will make an electrolytic solution?
Novosadov [1.4K]

Answer: KBr will make an electrolytic solution

Explanation:

Electrolyte is a substance which dissociates into ions when dissolved in water and thus is able to conduct electric current through them.

Compounds in solid form does not conduct electricity due to the absence of free ions.

a) SO_2 is a covalent compound and thus not an electrolyte.

b) C_2H_5OH  is a covalent compound and thus do not dissolve in water and thus is not an electrolyte.

c) KBr  is an ionic compound and thus dissolve in water and give ions which help to conduct electricity.

KBr\rightarrrow K^++Br^-

d) CCl_4  is a covalent compound and thus do not dissolve in water and thus is not an electrolyte.
