What is the molar mass of (NH), CO?<br> 138g<br> 788<br> 968<br> 1448
aleksandr82 [10.1K]

Answer:

The molar mass of (NH_{4})_{2}CO_{3} is 96.8 g/mol

Explanation:

The given molecular formula - (NH_{4})_{2}CO_{3}

Individual molar masses of each element in the compound is as follows.

Molar mass of nitrogen - 14.01 g/mol

Molar mass of of hydrogen = 1.008g/mol

Molar mass of carbon = 12.01 g/mol

Molar mass of oxygen =16.00 g/mol

Molar mass of (NH_{4})_{2}CO_{3} is

2\times[1(14.01)+4(1.008)]+1(12.01)+3(16.00)= 96.8g/mol

Therefore,The molar mass of (NH_{4})_{2}CO_{3} is 96.8 g/mol

-BARSIC- [3]

Answer:

NaCl + Ag(NO₃) --> Na(NO₃) + AgCl

Explanation:

Chemical equation:

NaCl + Ag(NO₃) --> Na(NO₃) + AgCl

The given reaction represent the double displacement reaction. Anion and cation of both reactant exchange with each others.

The anion of sodium chloride(Cl⁻) combine with cation of silver nitrate Ag⁺ and  NO₃⁻ combine with Na⁺.

The third equation is correct while others are in correct.

Double replacement:

It is the reaction in which two compound exchange their ions and form new compounds.

AB + CD → AC +BD

Semmy [17]

Answer:

A. True

Explanation:

The octane number is determined by comparing the characteristics of gasoline to isooctane (2,2,4-trimethylpentane) and heptane. The correct option is option A.

Basically, the higher the octane  number, the  greater the resistance of the gasoline to knocking.
