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%
Answer:
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)
is a covalent compound and thus not an electrolyte.
b)
is a covalent compound and thus do not dissolve in water and thus is not an electrolyte.
c)
is an ionic compound and thus dissolve in water and give ions which help to conduct electricity.

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