Answer:
The answer to your question is 50.76 g of H₂O
Explanation:
Data
mass of water = ?
mass of Li₃N = 32.9 g
Process
1.- Write the balanced chemical reaction
Li₃N + 3H₂O ⇒ 3LiOH + NH₃
2.- Calculate the molar mass of Li₃N and H₂O
Li₃N = (3 x 7) + (1 x 14) = 35 g
H₂O = (2 x 1) + (16 x 1) = 18 g
3.- Use proportions to calculate the mass of water
35 g of Li₃N ---------------- (3 x 18) g of water
32.9 g of Li₃N ------------ x
x = (32.9 x 54)/35
x = 1776.6/35
x = 50.76 g of H₂O
I think it is B for the answer
An increase in the frequency of effective collisions because it is these collisions that cause reactants to change to products
Answer:
the total density of the mixture = 3.415 x 10^3 g/mL
Explanation:
given:
density of a substance is 3.4 x 10^3 g/mL
Mixing it with another substance increases the density by 1.5 x 10^1 times.
find:
What is the density of the mixture?
-------------------------------------------------
let density (a) = 3.4 x 10^3 g/mL
density(b) = 1.5 x 10^1 g/mL
since there is no specific density provided for the mixture, we then add both to increase the density,
total density = density(a) + density(b)
total density = 3.4 x 10^3 g/mL + 1.5 x 10^1 g/mL
total density = 3.415 x 10^3 g/mL
therefore,
the total density of the mixture = 3.415 x 10^3 g/mL
