Answer:
Explanation:
The pressure is constant, so we can use Charles' Law.
Data:
V₁ = 1.92 × 10³ L; T₁ = 20 °C
V₂ = ?; T₂ = 68 °C
Calculations:
(a) Convert temperatures to kelvins
T₁ = (20 + 273.15) K = 293.15 K
T₂ = (68 + 273.15) K = 341.15 K
(b) Calculate the volume
The new volume of the gas is .
Alcohol is the answer. On plato its the right answer i hope it helps.
When comparing the reactivity of aluminum or magnesium to the reactivity of silver, we will find that both aluminum and magnesium are more reactive than silver.
Therefore, magnesium or aluminum can both replace the silver in the silver sulphide.
That's why <span>a piece of aluminum or magnesium can be used to remove tarnish, which is mostly silver sulfide, on silverware.</span>
Answer:
C. 10^-7.
Explanation:
Hello,
By taking into account that the eventual added ion to the water is removed, it means that after the time goes by, to water will remain pure, so one knows that it implies a pH of 7. Such pH is related with a Ka of 10^-7 based on the mathematical description of pH:
As long as matches with Ka, it turns out into:
Best regards.
Answer:
One other factor is the number of electrons removed. The potassium atom has one electron removed to for the corresponding ion, while calcium loses two electrons. The addition of electrons always results in an anion that is larger than the parent atom.
