Answer:
New Volume = 0.013 Liter
Explanation:
Combined Gas Law Problem
P₁V₁/T₁ = P₂V₂/T₂
P₁ = 1 atm
V₁ = 1.2 Liters
T₁ = 0°C = 273 K
P₂ = 100 atm
V₂ = V₁(P₁/P₂)(T₂/T₁)
T₂ = 15°C = (273 + 15)K = 288K
P₂ = 1.2L(1atm/100atm)(288K/273K) = 0.013 Liter
The answer will be A & B not only because it makes sense but evaporation is taking water away not adding to (gaining)
The answer is D. obsidian. Or at least I think it is. Just guessing based off me playing Minecraft 6 years ago haha
<u>Answer:</u> The solubility of nitrogen gas at 5.00 atm is
<u>Explanation:</u>
To calculate the molar solubility, we use the equation given by Henry's law, which is:
Or,
where,
are the initial concentration and partial pressure of nitrogen gas
are the final concentration and partial pressure of nitrogen gas
We are given:
Putting values in above equation, we get:
Hence, the solubility of nitrogen gas at 5.00 atm is
The % yield if 200g of chlorine react with excess Potassium bromide to produce 410g of bromine is calculated as below
% yield = actual yield/theoretical yield x100
the actual yield = 410 grams
calculate the theoretical yield
by first calculate the moles of chlorine used
mole= mass/molar mass
molar mass of Cl2 = 35.5 x2= 71 g/mol
moles= 200g/71g/mol = 2.82 moles
cl2 +2 KBr = 2KCl +Br2
by use of mole ratio between Cl2 to Br2 which is 1:1 the moles of Br2 is also = 2.82 moles
theoretical mass = moles x molar mass
molar mass of Br2= 79.9 x2= 159.8 g/mol
moles= 2.82g x 159.8 g/mol = 450.64 grams
% yield is therefore = 410g/450.64 x100 = 90.98 %
