The standard reaction free energy =δg0−311.kj for this reaction: p4 (s) + 20hf (g) → 4pf5 (g) + 10h2 (g) use this information to complete the table below. round each of your answers to the nearest kj .

Answers are:
Standard reaction: P₄ + 20HF→ 4PF₅ + 10H₂.
1) chemical reaction: 1/5P₄ + 4HF→ 4/5PF₅ + 2H₂.
ΔG = -311kJ ÷ 5 = -62,2 kJ.
2) chemical reaction: 12PF₅ + 30H₂ → 3P₄ + 60HF.
ΔG = -311kJ · (-3) = 933 kJ.
3) chemical reaction: 4PF₅ + 10H₂ → P₄ + 20HF.
ΔG = -311kJ · (-1) = 311 kJ, reversed standard reaction.

The independent variable is the type of music.the dependent variable is the pulse rate.the intervening variable is the age of the subject.if the mother does not like rock, her pulse is likely to not increase.the same might be true for the sister.the friend may like rap and gets excited.to establish cause/effect relationship, all of the subjects must be consistent.hope i .
