Answer:
144g of H₂O
Explanation:
3NH₄ClO₄(s) + 3Al → Al₂O₃(s) + AlCl₃(s) + 3NO(g) + 6H₂O(g)
From the equation:
3 moles of NH₄ClO₄ produced 6 moles of H₂O
4 moles of NH₄ClO₄ produced ? moles of H₂O
(4 ₓ 6)/3 = = 8 moles of H₂O
1 mole of H₂O = (1 × 2) + 16 = 18g (The Relative Molecular mass of H₂O)
8 moles of H₂O = ?
Therefore 8 × 18 = 144g
=144g of H₂O
Yes, an electron cause an electromagnetic wave to vibrate.
<h3>What is an electromagnetic wave?</h3>
One of the waves is propagated by simultaneous periodic variations of electric and magnetic field intensity and that includes radio waves, infrared, visible light, ultraviolet, X-rays, and gamma rays.
Electromagnetic waves are produced when something vibrates—an electric charge that moves back and forth.
When an electric charge vibrates, the electric field around it changes. Because the electric charge is in motion, it also has a magnetic field around it.
This magnetic field also changes as the charge vibrates.
Therefore, an electron causes an electromagnetic wave to vibrate.

<h3><u>Answer and Explanation;</u></h3>
The reaction between Nitrogen and Hydrogen to form ammonia gas is given by the equation;
N₂ + 3H₂ → 2NH₃
From the equation 1 mole of nitrogen gas (28 g) requires 3 moles of hydrogen gas (6 g) to form 2 moles of Ammonia gas (34 g).
Therefore;
Moles of Nitrogen = 14/28 = 0.5 mole
Moles of Ammonia = 16.1 /17 = 0.947 ≈ 1 moles
Therefore;
0.5 mole of nitrogen gas (14 g) requires 1.5 moles of hydrogen gas (3 g) to form 1 mole of Ammonia gas (17 g).
The balanced equation would be;
N₂ + 3H₂ → 2NH₃
Answer:
If NaOH of a known concentration neutralizes HCl of an unknown concentration, then you can use the volumes to determine the concentration of the HCl, because, at the equilibrium point, the number of moles of HCl equals the number of moles of NaOH.
