If this is an option for u hopefully it helps I’m not sure tho I searched it
<span>When a compound is decomposed into constituent elements, the amount of elements produced will remain in the same proportion every time it is decomposed. When the second sample of calcium fluoride is decomposed, the proportion of calcium and fluorine should remain same as first time.
Hence, calcium produced = 294 * 0.154/0.146 = 309 mg or 0.309 g</span>
Doubling the mass doubles the energy, while doubling the velocity quadruples it. Your question is basically about order of operations; the exponent only applies to the variable it's immediately on. As you note, you'd have to put parentheses to make it cover the
m as well. We say that energy is linear in mass, but quadratic in velocity.
