Answer:
D. 13
Explanation:
For most elements other than hydrogen, isotopes are named for their mass number. For example, carbon atoms with the usual 6 neutrons have a mass number of 12 (6 protons + 6 neutrons = 12), so they are called carbon-12. Carbon atoms with 7 neutrons have an atomic mass of 13 (6 protons + 7 neutrons = 13).

Answer:
Bellow
Explanation:
You have the detailed explanation on the other answer
2) 6÷2.2= 2.72 kg
3) 42.5÷2.2= 19.31 kg
19.31 - 9.6= 9.71 kg difference
4) 700÷2.2 = 318.18 kg
5) now is a bit different
2.2 lbs _____1kg
X lbs _____14.6 kg
2.2×14.6 =32.12 lbs
6) 2.2×1.4=3.08 lbs
Answer: Explanation:
A number used to multiply a variable. Example: 6z means 6 times z, and "z" is a variable, so 6 is a coefficient. ... Example: In ax^2 + bx + c, "x" is a variable, and "a" and "b" are coefficients.
