Why do some cells make food molecules?
kvasek [131]

Answer:

All living cells release energy from food  molecules through cellular breathing and/or fermentation. Some cells make food molecules using light energy through the process of (making food from light).

Making food from light- Photosynthesis

Breathing- Respiration

All living units give out power for a given time from food small complex units through formed of small units breathing and or fermentation. Some units make food small complex units using light power for a given time through the process of (making food from light).

The monomer of poly(vinyl chloride) has the formula C2H3Cl. If there are 1,565 repeat units in a single chain of the polymer, wh
monitta

Answer:

\large \boxed{9.780 \times 10^{4}\text{ u}}

Explanation:

The molecular mass of a monomer unit is:

C₂H₃Cl = 2×12.01 + 3×1.008 + 35.45 = 24.02 + 3.024 + 35.45 = 62.494 u

For 1565 units,

\text{Molecular mass} = \text{1565 units} \times \dfrac{\text{62.494 u}}{\text{1 unit }} = \mathbf{9.780 \times 10^{4}}\textbf{ u}\\\\\text{The molecular mass of the chain is $\large \boxed{\mathbf{9.780 \times 10^{4}}\textbf{ u}}$}
