The action force is you sitting on the chair and the reaction force is the gravity on the chair that is caused by you sitting on the chair
You’ve not put anything below so I’m not sure what the options are but the relative charge of a proton is +1
Strongest reducing agents are in Group 1 . For example lithium. The strongest oxidising agents are in Group 7 , For example Fluorine.
Answer:
50. 5mol
Explanation:
The mass of Zinc required = 3.30 kg = 3300 grams
The relation between moles and mass is:

Atomic mass of Zinc = 65.38g/mol


The answer to three significant figures will be 50.5 mol
Answer:
0.24
Explanation:
We are given that
Rate constant for A=
Rate constant for B,k'=0.0750/s
We have to find the value of equilibrium constant for the reaction

Equilibrium constant, for k=
Using the formula

Hence, the value of the equilibrium constant for the reaction
at this temperature=0.24
