The balanced chemical reaction:
<span>5C + 2SO2 → CS2 + 4CO
</span>
We are given the amount of coke to be used for the reaction. This will be the starting point for the calculations.
8 mol C ( 1 mol CS2 / 5 mol C ) = 1.6 mol CS2
Reaction equation:
Zn + 2HCl → ZnCl₂ + H₂
One mole of gas occupies 22.4 L at STP
Moles of H₂ = 112/22.4
= 5 moles
The theoretical amount of Zn needed is 5 mol
The actual amount = 5/0.85
= 5.88 moles
mass = moles x Mr
mass = 5.88 x 65
mass = 382.2 g
The answer is D.
Answer:2H₂+ O₂→ 2H₂O the reactants are 2H₂ and O₂ ... if the theoretical yield is 95 g of water after the chemical reaction you may have only 45g of water
i think
Explanation:
The temperature in K is 767.4 K
<u><em> calculation</em></u>
This is calculated using the ideal gas equation
that is PV =nRT
where;
P(pressure)= 28 atm
V(volume) = 0.045 L
n(number of moles)= 0.020 moles
R( gas constant) =0.0821 L.atm/mol.K
T(temperature)= ? K\
make T the subject of the formula by diving both side of equation by nR
T =PV/nR
T ={ (28 atm x 0.045 L) /( 0.020 mol x 0.0821 L.atm/mol.K)} =767.4 K
I think the answer is water/ Liquid.
If it’s incorrect, I’m sorry
