Answer:
when the forward and reverse reactions occur at equal rates.
chemical reaction is in equilibrium when the concentrations of reactants and products are constant - their ratio does not vary.
Answer:
The correct statement is that the point of initial resistance is the level of depression that will fill the pipette with the desired volume of solution.
Explanation:
The pipette can be otherwise stored vertically or horizontally, this has nothing to do with the operation, and before the operation, the dial needs to be set. Also, the plastic pipette tip should not be ejected at all, thus, no new disposable plastic tip is required for each sample.
The correct statement is that the point of initial resistance is the level of depression that will fill the pipette with the desired volume of solution.
Entropy is a measure of chaos or disorder in a system. For the first one, the system with the highest entropy is a cup of water at 0 degress centigrade. For the second question, the system with the lowest entropy is sugar crystals in 95 degrees centigrade cup of coffee.
I believe it’s A but I could be wrong
