Answer:
No
Explanation:
No, Ana's prediction of sorting out : mixture 1 'marble salt' with by her fingers, ie handpicking is not right.
Marble & salt particles mixture can't be sorted by handpicking. They can be seperated by the method of sieving rather, as marble particles being bigger stay in the sieve & salt particles being smaller (finer) pass through it.
The interaction between the substances and stomata is a chemical reaction, light energy strikes at the chlorophyll molecules, whose electrons gets excited to a state of higher energy, and they come back to their state of lower energy by emission of energy, which is accepted by a chain of acceptors, and energy is generated.
The correct answer would be <span>5.43 x 10^-4</span>
False. Due to:
Entropy increases with molecular size (mass of compound)
HBr has greater molecular size (molar mass) than HCl
The value of standard entropy of HCl(g) is 187 joules/ kelvin
The value of standard entropy of HBr(g) is 199 joules / kelvin
