I feel u r working with the chapter Mechanism of liquid
but I could understand ur question....
They are more likely to appear in the early morning or later afternoon.
Answer:
At the higher altitude, the new volume is 750.2L
Explanation:
If we decompose the Ideal Gases Law for the two situations (initial and final), we can determine this relaion:
P₁ . V₁ / T₁ = P₂ . V₂ / T₂
Number of moles does not change, and R stays the same.
Let's make some conversions, before:
752 mmHg . 1 atm / 760mmHg = 0.989 atm
24.3°C + 273 = 297.3K
0.0708 bar . 0.986 atm / 1bar = 0.070 atm
-5.41°C + 273 = 267.59 K
We replace: (0.989 atm . 59L) / 297.3K = (0.070 atm . V₂) / 267.59K
[(0.989 atm . 59L) / 297.3K] . 267.59K = 0.070 atm . V₂
52.5 atm.L = 0.070 atm . V₂
V₂ = 52.5 atm.L / 0.070atm = 750.2L
Answer:
A: Calcium is a group 2 element with two valence electrons. Therefore, it is very reactive and gives up electrons in chemical reactions. It is likely to react with an element with six valence electrons that “wants” to gain two electrons. This would be an element in group 6, such as oxygen.
