<span>All collisions between atoms or molecules are perfectly elastic and are not the result of any attractive forces is the best answer in my opinion since ideal gas particles have elastic collisions and do not interact with each other.</span>
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:
P2 = 226.6 kPa (Approx)
Explanation:
Given:
Temperature t = 25ºC
Old volume v1 = 145 ml
Old pressure p1 = 125 KPa
New volume v2 = 80 ml
Find:
New pressure p2
Computation:
p1v1 = p2v2
125 x 145 = P2 x 80
P2 = 226.6 kPa (Approx)
Answer:
glcolysis
Explanation:
Glcolysis uses glucose to create ATP within the cytoplasm of the cell.
Answer : For the experiment to study the diffusion across the semi permeable membrane, following are the safety steps that will help to handle chemicals safety;
- Use droppers to transfer small amounts of chemicals into another glassware, it will prevent the unnecessary spillage of the chemical.
- Use tongs to move hot objects as they may cause severe burns.
- Check the test tubes for chips prior to using them otherwise it may leak the chemical inside it
- Washing your hands after you finishing the lab experiment, this will ensure that food is not contaminated while consuming, with the chemicals that were stuck on the hands.
