Answer : The pressure of the gas is, 0.964 atm
Solution : Given,
Volume of gas = 9040 ml = 9.040 L (1 L = 1000 ml)
Moles of gas = 0.447 moles
Temperature of gas = 
Using ideal gas equation,
where,
P = pressure of the gas
V = volume of the gas
T = temperature of the gas
n = number of moles of gas
R = gas constant = 
Now put all the given values in this formula, we get the pressure of the gas.
By rearranging the terms, we get
Therefore, the pressure of the gas is, 0.964 atm
The answer is 4.0 moles of magnesium
because...
..
...4.0mol Makmol O2 =3.0mol O2
Answer:
When an electric charge moves, heat is dissipated due to the drift velocity hence current is induced
Answer:
The Chemical formula of sodium is Na.
The Chemical formula of oxide is O.
Explanation:
Therefore we know that the term 'valency' is called as the combining capacity of an atom of an element.
So by taking the valency of Sodium and Oxide, we get
Sodium with valency '1' and Oxide with valency '2'.
Na O
1 2
When you cross over you get 'Na2O' as the formula for sodium oxide.
