After reading all the options represented above, I nodiced that four of them are connected to chemistry, and the only activity that was performed by a chemist is primarily based on an understanding of physics is the third option from the box. C)predicting the boiling point of a liquid, given its pressure
while sdudying physics you often come across with such tasks where you need to find the boiling point by using the capability of reservoir with water and its size etc.
Answer:
Volume is directly related to moles
Explanation:
Answer:
21g
Explanation:
no.ofmol fe2o3=39.5/(56×2+16×3)=0.25mol
from equation 1mole fe2o3 react with 3mole co
so,0.25mol fe2o3 react with 0.75mol co
mass of co=0.75×(12+16)=21g
Answer:
Balanced forces are equal in size and opposite in direction. When forces are balanced, there is no change in motion. In one of your situations in the last section, you pushed or pulled on an object from opposite directions but with the same force. You observed that the object did not move.

hope this helps if not im sorry
Hello friends..
find the MW of HP
calculate the # of mols per 100g of HP
take the # of mols times 6.023 x 10^23 times 2 (2 H per molecule)
Hope it helps you..
