Answer: Light, Thermal, Kinetic
Explanation:
The lamp converts the electric energy to light energy.
The toaster converts the electric energy to thermal energy.
The fan converts the electric energy to kinetic energy.
Good luck with your test!
(a) 33.6 L of oxygen would be produced.
(b) 106 grams of
would be needed
<h3>Stoichiometric calculations</h3>
1 mole of gas = 22.4 L
(a) From the equation, 2 moles of
produce 3 moles of
. 1 mole of
will, therefore, produce 1.5 moles of
.
1.5 moles of oxygen = 22.4 x 1.5 = 33.6 L
(b) 22.4 L of
is produced at STP. This means that 1 mole of the gas is produced.
From the equation, 1 mole of
requires 1 mole of
.
Molar mass of
= (23x2)+ (12)+(16x3) = 106 g/mol
Mass of 1 mole
= 1 x 106 = 106 grams
