Answer:
V₂ = 167 cm₃
Explanation:
Because you are only dealing with volume and temperature, you can use Charles' Law to find the missing value. This formula looks like this:
V₁ / T₁ = V₂ / T₂
In this formula, "V₁" and "T₁" represent the initial volume and temperature. "V₂" and "T₂" represent the final volume and temperature. You have been given values for all of the variables except for final volume. Therefore, by plugging these values into the formula, you can simplify to find your answer.
V₁ = 100 cm³ T₁ = 150 °C
V₂ = ? T₂ = 250 °C
V₁ / T₁ = V₂ / T₂ <---- Charles' Law formula
(100 cm³) / (150 °C) = V₂ / (250 °C) <---- Insert values
(0.667) = V₂ / (250 °C) <---- Simplify left side
(0.667) x (250 °C) = V₂ <---- Rearrange
167 = V₂ <---- Simplify left side
Answer:
A
Explanation:
In genetic terms, a dominant trait is one that is phenotypically expressed in heterozygotes
1/2 - 3/7 = 7/14 - 6/14 = 1/14
Wat is considered a compound of hydrogen and oxygen and not a mixture because hydrogen and oxygen have gone through a chemical process to form the compound h2O. A mixture can generally be easily separated whereas a compound must undergo another chemical process to separate its elements. Therefore to separate oxygen and hydrogen from water a chemical process is necessary.
