The answer is D, medical diagnosis
You can start by recycling plastic and paper more often! Pick up trash that you see laying in the street and don’t add to it by littering!
Answer:
6g O2
Explanation:
Mole to mole ratio:
A balanced chemical equation shows a chemical reaction while maintaining the law of conservation of mass. The coefficients of the substances are known to be very helpful in computations as they represent the equivalent amounts of moles of the species that would be participating in the reaction.
We set up the chemical equation and then find the balanced chemical expression.
S+O2→SO3
Balance
2S+3O2→2SO3
We use the following values for the variables:
mS=4.0 gm
We proceed with the solution.
mO2= 4 g S × 1 mol S/ 32 g S × 3 mol O2/ 2 mol S × 32g O/ 1 mol O2
mO2 = 6 g
