The answer is a. The arteries are red and transfer blood to the heart. Veins are blue and transfer blood away from the heart and to all of the different parts of the body. The capillaries are in-between the veins and arteries and provide blood to cells.
ΔG deg will be negative above 7.27e+3 K.
<u>Explanation:</u>
- The ΔG deg with the temperature can be found using the formula and the formula is given below
- ΔG deg = ΔH deg - T ΔS deg
- Given data, ΔH deg = 181kJ and ΔSdeg=24.9J/K
- -T ΔS deg will be always negative and ΔG deg = ΔH deg will be positive and ΔG deg will be negative at relatively high temperatures and positive at relatively low temperatures
- solving the equation and substitute ΔGdeg=0
- ΔGdeg = ΔHdeg - T ΔSdeg
- T= ΔHdeg/ΔSdeg
- T=181 kJ / 2.49e-2 kJK-1
- By simplification we get
- T=7.27 × 10^3 K.
- Therefore, Go will be negative above 7.27 × 10^3 K
- Since ΔG deg = -RT lnK, when ΔGdeg < 0, K > 1 so the reaction will have K > 1 above 7.27 × 10^3 K.
- ΔG deg will be negative above 7.27e+3 K.

Answer:
=71.439911 u
Explanation:
We know that 1 mass of hydrogen atom = 1.00784 u
If it's measured at 72u: 72/1.00784=71.439911 u
Answer is: quantity of sulfur is 13 tons.
Chemical reaction: S(s) + O₂(g) → SO₂(g).
From chemical reaction: n(S) : n(SO₂) = 1 : 1.
n(S) = n(SO₂); amount of substance.
m(S) ÷ M(S) = m(SO₂) : M(SO₂).
m(S) : 32 g/mol = 26 t : 64 g/mol.
m(S) = (32 g/mol · 26 t) ÷ 64 g/mol.
m(S) = 13 t = 13000 kg; mass of sulfur.
