Answer:
M = 0.177
Explanation:
First, we have to find the molar mass of potassium iodine (KI).
K = 39.098
I = 126.904
Now, add these values together to get the molar mass of KI
39.098 + 126.904 = 166.0028
Now, it's time to do a grams to moles conversion.
35.0 g KI * 
= 
= 0.212 mol KI
Now, we can find the molarity of this solution.
Molarity (M) = 
M = 
= 0.177 M
The molarity (M) of this solution is 0.177.
Answer:
helium
Explanation:
coz it take part In fusion reaction
Answer:
The oxidation number of strontium is +2.
Explanation:
Answer :-
None of the forward reaction or backward reaction will be faster at equilibrium as
definition of equilibrium is that phase in which the rate of formation of product from reactant and rate formation of reactant from product is equal
and hence , both will be form at equal rate !!
Answer:
2. 100 times more hydroxide ions,
Explanation:
Acidity and alkalinity are measured with a logarithmic scale called pH. Each one-unit change in the pH scale corresponds to a ten-fold change in hydrogen ion concentration. Therefore, a 1.0 liter aqueous solution with a pH of 5.0 contains 100 times more hydronium ions than a 1.0 liter aqueous solution with a pH of 7.0
