wow, that sounds very painful I wonder why she did it...?
Explanation:
Answer:
158.5g Zn are produced
Explanation:
To solve this question we have to find the moles of Aluminium. With the moles of Aluminium and the balanced reaction we can find the moles of Zn and its mass as follows:
<em>Moles Al -Molar mass: 26.98g/mol</em>
43.6g Al* (1mol/26.98g) = 1.616 moles Al
<em>Moles Zn:</em>
1.616 moles Al * (3mol Zn / 2mol Al) =
2.424 moles Zn are produced
<em>Mass Zn -Molar mass: 65.38g/mol-</em>
2.424 moles Zn * (65.38g / mol) =
<h3>158.5g Zn are produced</h3>
The pressure of the gas is 3.52 atm
<u><em>calculation</em></u>
This is calculated using the Boyle's law formula
that is P1V1= P2V2 where;
P1 = 1.65 atm
V1 =22.8 L
P2 =? atm
V2 = 10.7 L
make P2 the subject of the formula by dividing both side by V2
P2 = P1V1 / V2
P2 = (1.65 atm x 22.8 l) / 10.7 L = 3.52 atm
According to Dalton's Law of Partial pressure, the pressure exerted by a mixture of non-reacting gases is equal to the sum of their partial pressure.
Mathematically,
Total Pressure = P₍₁₎ + P₍₂₎ + P₍₃₎ + ....... ------(1)
Data given:
Partial pressure of Nitrogen = P₍₁₎ = 587 mmHg
Partial pressure of Oxygen = P₍₂₎ = 158 mmHg
Partial pressure of Argon = P₍₃₎ = 7.00 mmHg
Putting these values in eq 1.
Total Pressure = 587 mmHg + 158 mmHg + 7 mmHg
Total Pressure = 752 mmHg
