The answer is a, because the question is referring to partial pressures. Partial pressures are a mere sum, no halving or doubling of anything is necessary.
So, A
Hope this helped :)
Area is length times width, so you would want to undo that. Since this is a square and the sides are equal, you would find the square root of 81 which is 9. Each side of the square is 9 meters
Answer:
C) low activation energy of forward reaction
Explanation:
Activation energy for the forward reaction is the quantity of free energy which is needed for a reaction to move from the reactant phase of energy level to the transition state of energy level. The higher the rate of energy level, the slower the chemical reaction.
Activation energy is a barrier that must be overcome for a reaction to take place.
Answer:
Explanation:
1. Find the molar concentration
Assume that we have 100 mL solution.
Mass of NaCl = 0.90 g
2. Find the osmotic pressure
The formula for osmotic pressure (Π) is
Π = icRT
T = (37 + 273.15) K = 310.15 K
D. The redox reaction is reversed lol..............
