Answer:
The total pressure will be 1, 021 atm
Explanation:
We apply Dalton's law, where for a gas mixture the total pressure is the sum of the partial pressures of each gas that makes up that mixture. The unit of pressure is converted into atm:
760mmHg----1 atm
542mmHg----x=(542mmHgx 1 atm)/760mmHg=0,713 atm
234mmHg----x=(234mmHgx 1 atm)/760mmHg=0,308 atm
Pt=P Ne + P At= 0,713 atm + 0,308 atm= <em>1, 021 atm</em>

We classify each of the reaction as follows:
<span>A. Pb(s) + Hg2SO4 (s) ---> PbSO4(s) +2 Hg(I)
Single replacement reaction
B. NaCI(aq) + AgNO3(aq) --->AgCI(s) +NaNO3(aq)
Double replacement reaction
C. 2H20(I)--->2H2(g) + 02(g)
Decomposition reaction

The atomic weight plays a dual role in chemistry. It is used to represent the mass of a single atom, molecule, or formula unit of a substance, in which case it has units amu/atom. It is also used to represent the mass of a mole of substance, in which case it has units g/mole.
