The balanced equation is:
Then proceed with the following equations.
The answer is
.
Answer:
D. 76%
Explanation:
Percent yield=actual/theoretical * 100
38/50 * 100 = 76%
Answer:
The molarity of the solution is 245, 2M.
Explanation:
We calculate the molarity, which is a concentration measure that indicates the moles of solute (in this case KCl03) in 1000ml of solution (1 liter):
0,25 L solution----- 61,3 moles of KCl03
1 L solution----x= (1 L solution x 61,3 moles of KCl03)/0,25 L solution
x=245, 2 moles of KCl03 --> <em>The molarity of the solution is 245, 2M</em>

Dalton is 1st, he made the atomic theory.
JJ Thomson is 2nd, he made the plum pudding model of the atom.
Earnest Rutherford is 3rd, he disproved the plum pudding model with alpha particles being shot at gold.
Bohr is 4th, he also made another model after Rutherford
