Answer:
There are number of molecules.
Explanation:
Given that,
Volume, V = 22.4 L
Temperature, T = 0°C = 273.15 K
Pressure, P = 1 atm = 1.013 bar
We need to find the number of molecules. Let there are n number of molecules. We know that, ideal gas law is as follows :
n = 0.999 moles
No. of molecules,
So, there are number of molecules.
Answer:
i think its CaCO3 + 2HCl → CaCl2 + H2O + CO2
Explanation:
Answer:
A. Actual Yield
Since all of the others are calculated not measured outright.
The mass of Calcium carbonate needed : 246 g
<h3>Further explanation</h3>
Reaction
CaCO₃(s)→CaO(s)+CO₂(g)
Conditions at T 0 ° C and P 1 atm are stated by STP (Standard Temperature and Pressure). At STP, Vm is 22.4 liters / mol.
Then for 55 L of CO₂, mol :
From the equation, mol ratio for mol CaCO₃ : mol CO₂ = 1 : 1, so :
mol CaCO₃ = mol CO₂ = 2.46
mass CaCO₃(MW=100g/mol) :
HF - The liquid state of this compound will exhibit hydrogen bonding due to the large electronegativity of H and F.
CF4 - The liquid state of this compound will exhibit van der Waals forces.
H2S - The liquid state of this compound will exhibit dipole-dipole or electrostatic attraction forces.
