54.936 grams of NaCl will be produced from 33.0 g of Na and 34.0 g of Cl.
Explanation:
Data given:
mass of Na = 33 grams
mass of
= 24 grams
atomic mass of Na = 23 grams/moles
atomic mass of Cl = 70 grams/mole
mass of NaCl formed =?
atomic mass of NaCl = 58.44 gram/mole
balanced chemical reaction:
2Na +
⇒ 2NaCl
number of moles = 
putting the values in the equation:
number of moles of Na = 
= 0.69 moles
number of moles of chlorine gas = 
= 0.47 moles
limiting reagent is chlorine gas in the reaction
from the balanced chemical reaction:
1 mole of chlorine gas reacts to form 2 moles of NaCl
then 0.47 moles of chlorine gas will form x moles
= 
x = 0.94 moles of NaCl is formed.
mass = atomic mass x number of moles
mass = 58.44 x 0.94
= 54.936 grams of NaCl is produced.
Answer:
P = 795.77 Mpa
Explanation:
Given that,
Force exerted by the hammer, F = 10⁴ N
The nail can be considered as a circle with radius of 
We need to find the pressure exerted on the wall. Pressure is equal to force acting per unit area. So

We know that, 1 MPa = 1000000 Pa
So, P = 795.77 Mpa
So, the pressure exerted on the wall is 795.77 Mpa.
3, 9, 16 are correct! 17 should be b because buffered means that it resists change in pH
Answer:
Electrical energy
