Answer:
45.03 mL.
Explanation:
- We can use the general law of ideal gas: <em>PV = nRT.</em>
where, P is the pressure of the gas in atm.
V is the volume of the gas in L.
n is the no. of moles of the gas in mol.
R is the general gas constant,
T is the temperature of the gas in K.
- If n and P are constant, and have different values of T and V:
<em>(V₁T₂) = (V₂T₁).</em>
V₁ = 50.0 mL, T₁ = 119ºC + 273 = 392 K,
V₂ = ??? mL, T₂ = 80ºC + 273 = 353 K.
∴ V₂ = (V₁T₂)/(T₁) = (50.0 mL)(353 K)/(392 K) = 45.03 mL.
Hi there!
The oxygen we breathe is classified as Chalcogen and Nonmetal.
It is a gas.
And, the atomic weight is 15.9994
Hope this helps you!

Answer:
Density of Ar gas under the given condition is 1.52 g/L
Explanation:
Density in grams/liter = (mass of Ar gas present in flask)/(volume of flask)
We know, number of moles = (mass)/(molar mass)
Molar mass of Ar = 39.948 g/mol
So, mass of 0.228 mol of Ar =
Volume of flask = 6.00 L
So, density of gas inside flask =
Hence, density of Ar gas under the given condition is 1.52 g/L
A is the anwser. Fuel in the ocean would cause pollution
True.
A hydrogen bond occurs when a hydrogen atom is covalently bonded to either oxygen, nitrogen, or fluorine.
