proton is the name for a nuclear particle that has about the same mass as a neutron, but with a positive charge.
(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

<span>S + O2 = SO2
1 mole S ------------- 1 mole SO2
( moles S ) --------- 15.0 moles SO2
moles S = 15.0 x 1 / 1
moles S = 15.0 / 1
= 15.0 moles S</span>
Physical change is the color, shape stuff like that and chemical change is once it’s changed it can’t go back
The first on is a and the second c I belive
