The law of conservation of energy states that energy is never created or destroyed only converted.
Answer:
43.2 mol C
115 mol H
158 mol of atoms
Explanation:
Step 1: Given data
Moles of C₃H₈: 14.4 mol
Step 2: Calculate the number of moles of C
The molar ratio of C₃H₈ to C is 1:3. The moles of C are 3/1 × 14.4 mol = 43.2 mol.
Step 3: Calculate the number of moles of H
The molar ratio of C₃H₈ to H is 1:(. The moles of H are 8/1 × 14.4 mol = 115 mol.
Step 4: Calculate the total number of moles of atoms
n = nC + nH = 43.2 mol + 115 mol = 158 mol

Answer:
The substances in a mixture can be separated using physical methods such as filtration, freezing, and distillation.
There is little, see Enthalpy of mixing, or no energy change when a mixture forms.
Mixtures have variable compositions, while compounds have a fixed, definite formula.
Explanation:
<span>rusting takes a long time, and rusting is a chemical change.</span>
