Answer:
<h2>The answer is option B</h2>
Explanation:
The mass of a substance when given the density and volume can be found by using the formula
mass = Density × volume
From the question we have
mass = 0.917 × 2.5 = 2.2925
We have the final answer as
<h3>2.3 g</h3>
Hope this helps you
No, because 40 miles is the same as nearly 25 km/h.
Answer: 34.4 g
Explanation:
As is in excess, is the limiting reagent and thus it will limit the formation of products.
According to stoichiometry:
2 moles of hydrogen produce = 1 mole of
2.5 moles of hydrogen produce = of
Mass of
But as % yield is 86%, mass of produded is
Thus 34.4 g of is produced.
Answer: The answer is C- comets!
Explanation: Callisto is composed mainly of rock and water ice, although other ices like ammonia ice and carbon dioxide ice may be present. Water ice occurs at the surface of Callisto so it would be comets.
