Answer: The percent ionization is higher for 0.010 M solution of
Explanation:
cM 0M 0M
So dissociation constant will be:
a) Given c= 0.10 M and = ?
Putting in the values we get:
b) Given c= 0.010 M and = ?
Putting in the values we get:
The percent ionization is higher for 0.010 M solution of
Well, in order to obtain the mass of the gas in grams, we have to find out the number of moles. Since the eqn is Moles = Mass(g)/ar or mr and if we reconfigure the eqn to Mass= moles × ar or mr. To find out moles, we have to derive it from the concentration of it since concentration= Mol/dm3 amd if we reconfigure the eqn to moles= concentration × dm3, we can obtain the numner of moles. After that, imput the number of moles into the eqn: mass= moles × ar or mr. Tada.
Oh yeah, you must know what is the gas in the tank. If not, it is impossible.
Ar means relative atomic mass
Mr means relative molecular mass.

Answer:</h3>
Pb₃O₄ + 4HNO₃ → 2Pb(NO₃)₂ + PbO₂ + 2H₂O

Explanation:</h3>
- Balancing a chemical equation involves putting appropriate coefficients on the reactants and products to make the number of atoms of each element involved equal on both sides of the equation.
- When a chemical equation is balanced then it obeys the law of conservation of mass.
- The law of conservation of mass requires the mass of reactants to be equal to the mass of the products.
- In this case, to balance the equation, we put the coefficients 1, 4, 2, 1 and 2 receptively on the equation.
Thus, the balanced equation will be;
Pb₃O₄ + 4HNO₃ → 2Pb(NO₃)₂ + PbO₂ + 2H₂O\
- Therefore, on the reactants side there are 3 Pb atoms, 16 O atoms, 4 H atoms and 4 nitrogen atoms.
- Product side : 3 Pb atoms, 16 O atoms, 4 H atoms and 4 nitrogen atoms.
Thus, the equation obeys the law of conservation of mass.
