Answer:
Explanation:
Since all sodium salts and all nitrates are soluble, the insoluble product must be lead(II) bromide.
The equation for the equilibrium is
PbBr₂ ⇌ Pb²⁺ + Br⁻
I/mol·L⁻¹: 0.0140 0.0024
= [Pb²⁺][Br⁻]²
[Pb²⁺] = 0.0140 mol·L⁻¹
[Br⁻] = 0.0024 mol·L⁻¹

In a nuclear explosion the human body can be irradiated by at least three processes. The first, and most major, cause of burns is due to thermal radiation and not caused by ionizing radiation. Thermal burns from infrared heat radiation, these would be the most common burn type experienced by personnel.
1. From the balanced equation given above, the ratio of the number of moles of the hydrocarbon and oxygen is equal to 2/7. Given that there are 2 moles of oxygen,
moles hydrocarbon = (2 moles O2)(2 moles HC / 7 moles oxygen)
Simplifying,
moles HC = 4/7 or 0.57 moles HC
Answer: 0.57 moles HC
2. The calculation for the mass of water is shown below with the dimensional analysis and conversion factors,
(30 g C2H6)1 mole C2H6/30 g C2H6)(6 molesH2O/2 moles C2H6)(18 g H2O/1 mole C2H6)
Simplifying,
mass = 54 grams of water
A the ratio decreases as pressure increases
