Answer:
Hg(NO₃)₂(aq) + Na₂SO₄(aq) → 2NaNO₃(aq) + HgSO₄(s)
Moles of Hg(NO₃)₂ = 55.42 / 324.7 ==> 0.1707 moles
Moles of Na₂SO₄ = 16.642 / 142.04 ==> 0.1172 moles
Limiting reagent is Na₂SO₄ as it controls product formation
Moles of HgSO₄ formed = 0.1172 moles
= 0.1172 x 296.65
= 34.757g
Explanation:
Data:
p (pressure) = 81.8 kPa = 81.8*10³ Pa ≈ 8.07 atm
v (volume) = ? (in L)
n (number of mols) = 0.352 mol
R (Gas constant) = 0.082 (atm*L/mol*K)
T (temperature) = 25ºC converting to Kelvin, we have:
TK = TC + 273 → TK = 25 + 273 → TK = 298
Formula:

Solving:




Answer:
- Option C) the chance of water-borne diseases.
Explanation:
When a <em>flood </em>happens, water will lpotentially get contaminated by several causes which include the overflow of untreated wastewater, the decomposition of the carcasses of animals and people, and the chemical contamination from industries.
In general, biochemical and chemical hazards are present in the water, after a flood, which means that the authorities and population should take extreme care for the use and intake of water: chemical treatment (use of chlorine), boil water. As usual, children and the elderly are the most at risk in those conditions.
Answer:
Partial pressure of Ne is 0.61 atm.
Explanation:
Mole fraction of a gas
in mixture = (no. of moles of the gas in mixture)/(total no. of moles of gases in mixture)
Here, total no. of moles of gases = (0.32 + 0.56) moles = 0.88 moles
So, mole fraction of Ne in mixture, 
Let's assume both He and Ne along with their mixture behaves ideally,
Hence, in accordance with Dalton's law of partial pressure-

Where,
and
are partial pressure of Ne and total pressure respectively.
So, 
So, partial pressure of Ne is 0.61 atm.
Answer:
Why would it be false? That would be a great magic act.
