1 mole of NH42SO4 contains 42 moles of H. We take the 42 moles of H and multiply that times Avogadro's number (6.02x10^23) and get 2.5284x10^25 atoms of hydrogen
<h2>Answer with Explanation </h2>
The energy transformation involved in heating soup in microwaves occurs due to microwave radiation. The radiant energy which also known as heat energy in the microwave causes the water molecules in the soup to gain kinetic energy. Hence, the molecules collide with each other more often causing the soup to heat up in form of waves that are built within the microwave. This is also the reason it is termed as mircowave due to release of waves.
Answer:
I believe the first one is correct but I think the second one would be the blood like substance. not a 100% sure sorry
Answer:
Option (e) should be discarded.
Explanation:
The given set of data is said to be precise if the values are close to each other. In this problem, a chemistry student is experimentally determining the boiling point of bromine.
In this case, all values are close to each other but option (e) i.e. 56.3° should be discarded to make his data precise.
