The reaction between ammonium sulfate and calcium hydroxide is given below.
(NH₄)₂SO₄ + Ca(OH)₂ --> 2NH₃ + CaSO₄ + 2H₂O
From the balance equation, we can conclude that every 74 g of calcium sulfate reacted with enough amount of ammonium sulfate will yield 34 grams of ammonia. From the given amount,
(20 g calcium sulfate) x (34 grams ammonia / 74 g calcium sulfate)
= <em>9.19 g ammonia</em>

Does a chemical bond join atoms together in a water molecule?

MrRissso [65]

Yes.

A covalent bond holds it together, which is chemical.

a gas is contained in a thick walled balloon. when the pressure changes from 417 mm hg to 576 mm hg, the volume changes from l t

melomori [17]

We can use the combined gas law equation to solve for the initial volume
$\frac{P1V1}{T1} = \frac{P2V2}{T2}$
parameters for the first instance are on the left side and parameters for the second instance are on the right side of the equation
substituting the values in the equation
$\frac{417 mmHg*V}{497 K} = \frac{576mmHg*4.78L}{386K}$
V = 8.50 L
the initial volume is 8.50 L
