5 0

Answer:

if you refer to "kinetic energy" of science then an examole of this would be a rock on a cliff suddenly falling.

Explanation:

kinetic energy is basically the action of a object or thing moving, coming into motion therefore in the example when the rock falls it is moving (in motion) making it kinetic energy

The theoretical yield of a reaction is the amount of product obtained if the limiting reactant is completely converted to produc
Elis [28]

Answer: 9.9 grams

Explanation:

To calculate the moles, we use the equation:

\text{Number of moles}=\frac{\text{Given mass}}{\text {Molar mass}}

a) moles of H_2

\text{Number of moles}=\frac{8.150g}{2g/mol}=4.08moles

b) moles of C_2H_4

\text{Number of moles}=\frac{9.330g}{28g/mol}=0.33moles

H_2(g)+C_2H_4(g)\rightarrow C_2H_6(g)

According to stoichiometry :

1 mole of C_2H_4 combine with 1 mole of H_2

Thus 0.33 mole of C_2H_4 will combine with =\frac{1}{1}\times 0.33=0.33 mole of H_2

Thus C_2H_4 is the limiting reagent as it limits the formation of product.

As 1 mole of C_2H_4 give =  1 mole of C_2H_6

Thus 0.33 moles of C_2H_4 give =\frac{1}{1}\times 0.33=0.33moles  of C_2H_6

Mass of C_2H_6=moles\times {\text {Molar mass}}=0.33moles\times 30g/mol=9.9g

Thus theoretical yield (g) of C_2H_6 produced by the reaction is 9.9 grams

For an ideal gas under constant volume, if the pressure is tripled, what happens to the Kelvin temperature?
EleoNora [17]

Answer:

Increase pressure 3X => increase Temperature 3X

Explanation:

Gay-Lussac Law => T ∝ P => T =kP => Empirical Relationship => T₁/P₁ = T₂/P₂  

=> T₂ = T₁P₂/P₁

Given P₂ = 3P₁ => T₂ = T₁(3P₁)/P₁ = 3T₁
