False. carbon-carbon bonds that share 2 pairs of electrons are double bonds. An unsaturated hydrocarbon isnt necessary to only have double bonds. they can also have single bonds or triple bonds.
CaO ( calcium oxide) is a basic oxide.
Answer:
27.9 mL
Explanation:
To find the new volume, you need to use the Charles' Law equation:
V₁ / T₁ = V₂ / T₂
In this equation, "V₁" and "T₁" represent the initial volume and temperature. "V₂" and "T₂" represent the final volume and temperature.
V₁ = 105 mL V₂ = ? mL
T₁ = 392 °F T₂ = 104 °F
V₁ / T₁ = V₂ / T₂ <----- Charles' Law
105 mL / 392 °F = V₂ / 104 °F <----- Insert values
0.26785 = V₂ / 104 °F <----- Simplify left side
27.9 = V₂ <----- Multiply both sides by 104
Answer:
The geological time from the longest to the shortest are:
- Eon,
- Era,
- Period and,
- Epoch.
Then the new pressure of the sample of nitrogen is 1.28 atm
So, option D is correct one.
Calculation,
Formula used :
(i)
Where , P is pressure and V is the volume
Given data,
= 3. 65 atm
= 21. 2 L
=
= 62. 6 L
= 22°C = 22+273 = 295 K
= 34°C = 34 +273 = 307 K
Putting the value of all data given in equation (i) we get,
3. 65 atm × 21. 2 L/295 K =
× 62. 6 L / 307 K
= 3. 65 atm × 21. 2 L × 307 K/295 K × 62. 6 L = 1.28 atm
Then the new pressure the sample of nitrogen is 1.28 atm
