Answer:
131 mg
Explanation:
Percent yield = 89%
Actual yield = 117 mg
Percent yield is given by

The theoretical yield, for this reaction is 131 mg.
Answer:

Explanation:
Florine has the highest electronegativity and it thus pulls the element of
groups in the COOH group towards itself, making it relatively easy to loose the proton of the carboxyl group.

Cs is the answer hope this helps!!!
The elements in each group have the same number of electrons in the outer orbital<span>. Those </span>outer<span> electrons are also called valence electrons. They are the electrons involved in chemical bonds with other elements. Every element in the first column (group one) has one electron in its </span>outer<span> shell.</span>
Answer:
4Ba(CO3) -> 4BaO2 + 2CO2
Explanation:
I looked at the oxygens to balance this. Ba(CO3) normally has 3 oxygens. BaO2 and CO2 have 4 oxygens total. The common multiple of 3 & 4 is 12. So there should be 12 oxygens on both sides. Then I just found the coefficients that would give 12 oxygens on both sides and can balance the rest of the atoms.
