Answer:
The statement 'If the reactions of A⟶D are rearranged, they become non spontaneous.' is false
Explanation:
Step 1: Data given
Reaction 1 (A⟶B) has a ΔG=+3 kJ/mol
Reaction 2 (B⟶C) has a ΔG=−6kJ/mol
Reaction 3 (C⟶D) has a ΔG=+1 kJ/ mol.
Step 2:
To be spontaneous ΔG should be negative (ΔG<0)
For reaction A⟶D; ΔG = 3kJ/mol -6kJ/mol + 1 kJ/mol = -2 kJ/mol
This means for the reaction A⟶D; the reaction is spontaneous
This means for the reaction D⟶A; ΔG = 2kJ/mol, so the reaction is non-spontaneous
For reaction 1 and 3 the reaction is ,non-spontaneous (but the reverse reaction is). Reaction 2 is driving reactions 1 and 3 forward. A⟶D is thermodynamically spontaneous.
The statement 'If the reactions of A⟶D are rearranged, they become non spontaneous.' is false

Answer:
Weather is describes as the term of the temperature, humidity, wind velocity, precipitation, and barometric pressure. It usually happens in the troposphere, or lower atmosphere. (Hope this helped!)

Answer:
The concentration of an acid in a solution can be determined by making an acid-base titration. To do this, a known volume of the acid solution is gradually added alkali solution whose concentration is known, until a neutral pH is reached.

d.
Explanation:
Mass of calcium = 4.00 g
Molar mass of calcium = 40.078 g/mol
<u>Moles of calcium = 4.00 / 40.078 moles = 0.9981 moles</u>
Given that the compound only contains calcium and bromine. So,
Mass of bromine in the sample = Total mass - Mass of calcium
Mass of the sample = 20.0 g
<u>Mass of bromine in sample = 20.0 - 4.00 g = 16.0 g</u>
Molar mass of bromine = 79.904 g/mol
<u>Moles of Bromine = 16.0 / 79.904 = 0.2002 moles
</u>
Taking the simplest ratio for Ca and Br as:
0.9981 : 0.2002 = 5 : 1
The empirical formula is =
