Answer:
24.66%
Explanation:
To find the percent of water (H2O) in the following compound: Zn3(PO4)2. 7H2O
The atomic mass of the elements are as follows:
Zn = 65g/mol
P = 31g/mol
O = 16g/mol
H = 1g/mol
Hence, molar mass of the compound is as follows:
65(3) + {31 + 16(4)} 2 + 7{1(2) + 16}
195 + 95(2) + 7(18)
195 + 190 + 126
511g/mol
Molar mass of 7H2O
= 7(18)
= 126g/mol
Hence, the percent of H2O in the compound is:
Molar Mass of 7H2O/molar mass of compound × 100
= 126/511 × 100
= 0.2466 × 100
= 24.66%
Hey there!
This atom has 26 protons, which means it is an iron atom, or Fe.
26 + 32 = 58
Charge is difference between protons and electrons.
26 - 24 = 2 (+)
We have 58, Fe, and 2+.
That means our answer is D. ⁵⁸Fe²⁺.
Hope this helps!
Answer:
Product: propan-1-ol
Explanation:
IIn this case, we have to remember that is a reduction agent. So, this is a <u>reduction reaction</u>. The has the ability to produce <u>hydride ions </u>. This ion can attack the <u>carbonyl group</u> generating a negative charge in the oxygen. In the next step, the negative charge in the oxygen can attack a water molecule to<u> protonate</u> the molecule and produce <u>propan-1-ol</u>.
See figure 1
I hope it helps!
the answer is hydrocarbons contain 10 hydrogen atoms :D
