A container of carbon dioxide has a volume of 260 cm at a temperature of 22.0°C. If the
Oxana [17]

Answer:

V₂ =279.4 cm³

Explanation:

Given data:

Initial volume = 260 cm³

Initial temperature = 22.0°C

Final temperature = 44.0°C

Final volume = ?

Solution;

22.0°C (22+ 273 = 295k)

44.0°C(44+273 = 317k)

Formula:

According to Charles's law

V₁/T₁ = V₂/T₂

Now we will put the values in formula:

V₂ = V₁×T₂ / T₁

V₂ = 260 cm³ × 317k / 295k

V₂ = 82420 cm³. k  / 295k

V₂ =279.4 cm³

In the allene (H2C=C=CH2) molecule:
Marina86 [1]

Answer:

Option c

Explanation:

In the allene, CH_2=C=CH_2

Central atom forms two sigma bond and two pi bond.

Hybridization of central atom = sp

Hybridization of two terminal C = sp^2

Allene is a nonplanar molecules. This is because of the planes of two CH_2 groups which are twisted 90 ° to each other.

Therefore, the two H atoms on one C lie above and below the plane defined by the other CH_2 group.
