Answer:
The difference in the number of protons and neutrons in atoms account for many of the different properties of elements.
If its sodium it would have 11 electrons
C or A I may be incorrect but those are what I think it is
Answer: Option (c) is the correct answer.
Explanation:
Activation energy or free energy of a transition state is defined as the minimum amount of energy required to by reactant molecules to undergo a chemical reaction.
So, when activation energy is decreased then molecules with lesser amount of energy can also participate in the reaction. This leads to an increase in rate of reaction.
Also, increase in temperature will help in increasing the rate of reaction.
Whereas at a given temperature, every molecule will have different energy because every molecule travels at different speed.
Hence, we can conclude that out of the given options false statement is that at a given temperature and time all molecules in a solution or a sample will have the same energy.
Answer: D. transverse
Explanation:
Light is a transverse wave, while sound is a longitudinal wave.
