Answer:
A. Hydrogen cans oxygen are reactants
Explanation:
Oxygen has a charge of -2. Hydrogen has a charge of +1. So it takes two hydrogens to balange the one oxygen hence the H20. So the reaction is balanced, and H20 is indeed made up of 1 oxygen and 2 hydrogen atoms. The equation 2 hydrogen + 1 oxygen (<---reactants) = Water (<--product) So hence Hydrogen cans oxygen is not a true statement. If cans is a misspelling then C would be your answer.

The earths gravity is possible
Answer:
[Ba^2+]= 0.400M
[OH-]= 0.800M
Explanation:
Step 1: Data given
Molarity ofBa(OH)2 = 0.400 M
Ba(OH)2 is a strong electrolyte, so 100 % dissociation
Step 2: The equation
Ba(OH)2 → Ba^2+ + 2OH-
In 1 mol Ba(OH)2 we have 1 mol Ba^2+ and 2 moles OH-
Step 3: Calculate the concentration
[Ba^2+]= 1* 0.400 M = 0.400M
[OH-]= 2*0.400 M = 0.800M

I think you forgot to give the options along with the question. I am answering the question based on my knowledge and research. "Test a third group that does not receive the supplement" would be the procedure that would have made the <span>outcome of this study more valid. I hope the answer helps you.</span>
