Answer:

0.659 mol

Explanation:

n(NH3)/n(N2) = 4/5

n(NH3) = 4/5×0.824

= 0.659 mol

An explosion that releases great amounts of heat is an example of
Damm [24]
<span>An explosion that releases great amounts of heat is an example of an exothermic process. Any reaction that gives off or releases energy as light, electricity, heat, or sound is considered to be exothermic, with "exo" meaning "outside". An explosion is one of the most extreme cases of exothermic reactions.</span>

Starting with lead (ii) carbonate describe how a solid sample of lead (ii) sulphate can be prepared
tatuchka [14]

The preparation of lead (ii) sulphate from lead (ii) carbonate occurs in two steps:

  1. insoluble lead carbonate is converted to soluble lead (ii) nitrate
  2. soluble lead (ii) nitrate is reacted with sulphuric acid to produce lead (ii) sulphate.

<h3>How can a  solid sample of lead (ii) sulphate be prepared from lead (ii) carbonate?</h3>

Lead (ii) carbonate and  lead (ii) sulphate are both insoluble salts of lead.

In order to prepare lead (ii) sulphate, a two step process is performed.

In the first step, Lead (ii) carbonate is reacted with dilute trioxonitrate (v) acid to produce lead (ii) nitrate.

  • PbCO₃ + 2HNO₃ → Pb(NO₃)₂ + CO₂ + H₂O

In the second step, dilute sulfuric acid is reacted with the lead (ii) nitrate to produce insoluble lead (ii) sulphate which is filtered and dried.

  • Pb(NO₃)₂ + H₂SO₄  →  PbSO₄ + 2HNO₃

In conclusion, lead (ii) sulphate is prepared in two steps.

What is the de Broglie wavelength (in nm) of a proton of traveling at 3.18% of the speed of light?
gulaghasi [49]
Answer is: <span>de Broglie wavelength of a proton is </span>3,4·10⁻⁵ nm.
v(proton) = 0,038 · 3·10⁸ m/s.
v(proton) = 1,14·10⁷ m/s; speed of proton.
m(proton) = 1,67·10⁻²⁷ kg.
h = 6,62607004·10⁻³⁴ m²·kg/s; Planck constant.
λ(proton) = h / m(proton) · v(proton).
λ(proton) = 6,62607004·10⁻³⁴ m²·kg/s ÷ (1,67·10⁻²⁷ kg · 1,14·10⁷ m/s).
λ(proton) = 3,48·10⁻¹⁴ m · 10⁹ nm/m = 3,4·10⁻⁵ nm.

How many molecules are in 3.50 moles of H2O<br>​
Debora [2.8K]

Answer:

2.11 x 10²⁴ molecules.

Explanation:

  • <em>It is known that every 1.0 mole of a molecule contains Avogadro's number of molecules (NA = 6.022 x 10²³).</em>

<em><u>Using cross multiplication:</u></em>

1.0 mole of H₂O contains → 6.022 x 10²³ molecules.

3.5 mole of H₂O contains → ??? molecules.

∴ 3.5 mole of H₂O contain = (3.5 mol)(6.022 x 10²³) = 2.11 x 10²⁴ molecules.
