Answer:
A. m C5H12 = 108.23 g
B. m F2 = 547.142 g
C. m Ca(CN)2 = 71.85 g
Explanation:
- mass (m) = mol (n) × molecular weigth (Mw)
∴ Mw C5H12 = ((12.011)(5)) + ((1.008)(12)) = 72.151 g/mol C5H12
∴ Mw F2 = (18.998)(2) = 37.996 g/mol F2
∴ Mw = Ca(CN)2 = 40.078+((12.011+14.007)(2)) = 92.114 g/mol Ca(CN)2
A. m C5H12 = ( 1.50 mol)×(72.151 g/mol) = 108.23 g C5H12
B. m F2 = (14.4 mol)×(37.996 g/mol) = 547.142 g F2
C. m Ca(CN)2 = (0.780 mol)×(92.114 g/mol) = 71.85 g Ca(CN)2
Answer:
The chemical compounds of living things are known as organic compound because of their association with organisms and because they are carbon-containing compounds, which are the compounds associated with life processes, are the subject matter of organic chemistry

Explanation :
Definition of potential energy : energy stored that depends upon the relative position of various parts of a system
Rdaioactive decay results in the formation of a different element. Plutonium decays by emitting alpha emission to form uranium. Thermal energy is emitted as the alpha particles are absorbed and the kinetic energy is converted to heat. The amount of energy is computed by the formula;
E = mc²
E = 0.000046 × (3 ×10^8)
Energy = 4.14 ×10^13 Joules
