(c) 23.3 mol carbon dioxide =
(d) 0.310 mol nitrogen (N2) = 
Explanation:
In one mole there are
atoms/molecules
(a) 0.294 mol silver =
(b) 8.98 * 10-3 mol sodium chloride -
(c) 23.3 mol carbon dioxide =
(d) 0.310 mol nitrogen (N2) =
True, the hardness of all materials in relative <span />
The relative atomic mass of x is 101 u.
Molar mass is calculated by adding the atomic mass of all the elements in a compound.
Molar mass of x(HCO₃) =162 g/mol
Atomic mass of H = 1 g/mol
Atomic mass of C =12 g/mol
Atomic mass of O = 16 g/mol
Therefore, molar mass of x(HCO₃) will be
= x + 1 + 12 + 3 x 16
We know that:
x + 1 + 12 + 3 x 16=162
x + 61 = 162
x = 101 g/mol
The relative atomic mass of x will be 101 u.

Answer:
Explanation:
1. Increasing the concentrations of reactants in a chemical reaction would affect a reaction positively by increasing the number of collisions within a particular period which in turn increases the rate of reaction.
2. The molecules gains energy,which enable them to move faster and collide with the right energy for a reaction to take place.
3. The average kinetic motion of molecules in a solution can be measured by measuring the temperature. Temperature is a measure of the average kinetic energy of molecules in a solution.
A molecule consists of two or more atoms united by a bond
