Answer:To calculate the Molarity of a 70 wt. % Nitric Acid the number of moles of HNO 3 present in 1 liter of acid needs to be calculated. Knowing the density of the acid to be 1.413 g/mL, we can calculate the weight of 1 L of 70% HNO 3 to be 1413
Explanation:
Answer : The value of is,
Explanation :
First we have to calculate the solubility in mole/L.
The balanced equilibrium reaction will be,
The expression for solubility constant for this reaction will be,
Now put the value of solubility in this expression, we get the of barium carbonate.
Therefore, the value of is,
For exothermic reaction, heat is one of the products. According to Le Chatelier's principle, the reaction would shift to production that would create equilibrium. The answer to this question is FALSE. Increasing the temperature of an exothermic reaction favors the reactants.
HCOOH ⇄ H⁺ + HCOO⁻
formic acid
Ka=[H⁺][HCOO⁻]/[HCOOH]
