D. i'm pretty sure. hope that helps!
Explanation:
Compound: a substance that is made up of more than 1 type of atom bonded together Example: H2O
Mixture: combination of two or more elements or compounds not chemicaly bonded together. example: Sugar and salt in one container
elements pure substance of an atom. Example: hydrogen
While waves that travel within the depths of the ocean are longitudinal waves
Explanation : the waves that travel along the surface of the oceans are referred to as surface waves. A surface wave is a wave in which particles of the medium undergo a circular motion. Surface waves are neither longitudinal nor transverse.
The answer is elements gain electrons. Oxidation reduction is elements lose electrons. And oxygen is added/lost can be a type of oxidation/reduction reaction.
Given the balanced chemical equation for combustion of propane:
Moles of propane =3.6 mol
Propane is the limiting reactant as the other reactant oxygen is said to be present in excess.
Amount of products formed would depend on the moles of limiting reactant.
Mole ratio of water to propane as per the balanced chemical equation
=
Calculating the moles of water produced from 3.6 mol propane:
= 14.4mol
Theoretical yield of water = 14.4 mol
Actual yield = 12 mol
Percent yield =
=
