The statements that are true regarding a catalyst are as follows:
It undergoes no permanent change during a reaction
It does not participate in a chemical reaction
What is a catalyst?
A catalyst is a substance that increases the rate of a chemical reaction without being consumed in the process.
A catalyst increases the rate at which a chemical reaction occurs by decreasing the activation energy of the reaction.
Since a catalyst is not used up in the reaction, the following statement applies:
It undergoes no permanent change during a reaction
It does not participate in a chemical reaction

Hey there!:
Molar mass NaOH = 39.997 g/mol
Number of moles ( solute )
n = mass / molar mass
n = 1.00 / 39.997
n = 0.0250 moles of NaOH
Volume in liters:
500.0 mL / 1000 => 0.5 L
Therefore:
Molarity = number of moles / Volume ( L )
Molarity = 0.0250 / 0.5
Molarity = 0.05 M
Hope that helps!
Answer:
Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that, through cellular respiration, can later be released to fuel the organism's activities.

Answer:
The mass of 4.5 moles of Cu(NO3)2 is 843.55g
Explanation:
Mass = moles x Molar mass
Mass = 4.50(187.55)
= 843.97g
