Answer: The mass of 
produced is, 149 grams.
Explanation : Given,
Mass of 
= 354.2 g
Molar mass of = 278 g/mol
Molar mass of = 58.5 g/mol
First we have to calculate the moles of
Now we have to calculate the moles of 
The balanced chemical equation is:
From the reaction, we conclude that
As, 3 moles of react to give 6 mole of
So, 1.27 moles of react to give 
mole of
Now we have to calculate the mass of
Therefore, the mass of produced is, 149 grams.
Answer earthquakes that's is easy
Explanation:
Answer:-
0.229 L
Explanation:-
Molar mass of AgBr = 107.87 x 1 + 79.9 x 1
=187.77 grams mol-1
Mass of AgBr = 150 grams
Number of moles of AgBr = 150 grams / 187.77 gram mol-1
= 0.8 mol
The balanced chemical equation is
NaBr (aq) + AgNO3 (aq)--> AgBr(s) + NaNO3(aq)
From the equation we can see that
1 mol of AgBr is produced from 1 mol of AgNO3.
∴ 0.8 mol of AgBr is produced from 1 x 0.8 / 1 = 0.8 mol of AgNO3.
Strength of AgNO3 = 3.5 M
Volume of AgNO3 required = Number of moles / strength
= 0.8 moles / 3.5
=0.229 L
For a solar eclipse t occur;
C. The moon is located from a line between the sun and earth
Answer is: 12 <span>moles of water will be produced.
</span>Balanced chemical reaction: N₂H₄ + O₂ → N₂ + 2H₂O.
n(N₂H₄) = 6 mol.
From balanced chemical reaction: n(N₂H₄) : n(H₂O) = 1 : 2.
n(H₂O) = 2 · n(N₂H₄).
n(H₂O) = 2 · 6 mol.
n(H₂O) = 12 mol.
n - amount of substance.
