Answer : The number of silver atoms produced will be
Explanation : Given,
Number of atoms of copper =
The given balanced chemical reaction,
From the balanced chemical reaction we conclude that,
As, number of copper atoms react to give number of silver atoms.
So, number of copper atoms react to give number of silver atoms.
Therefore, the number of silver atoms produced will be
2NaCl + Br2
This is because Na (Sodium) still needs to retain the coefficient or amount of two. Since Chlorine already has 2 on the reactants side, having a two in front would make sense so both elements can have a two.
Bromine would have the subscript of two as in the reactants side of the equation, it is also under the coefficient of two. Thus, it would need to carry it to the products side in order to keep the equation balanced.
Hope this helps!
Answer:
6.05 × 10⁴ cal
Explanation:
Step 1: Given and required data
Mass of water (m): 112 g
Enthalpy of vaporization of water (ΔHvap): 540 cal/g
Step 2: Calculate how much energy is required to vaporize 112 g of water
Vaporization is a physical change in which a substance goes from the liquid state to the gaseous state. We can calculate the energy required (Q) using the following expression.
Q = ΔHvap × m
Q = 540 cal/g × 112 g = 6.05 × 10⁴ cal
