Answer:

729

Explanation:

In a cube, the length, width, and height are equal.

If the length is 3cm, the volume is 27cm^3

Density Equation: p=mV

V=27cm^3

m=27g

Density= (27g)*(27cm^3)

Density = 729g/cm^3

D = m/v. v = (3)^3 = 27.
D = 27/27. D = 1g/cm^3

Draw a Lewis structure for ketene, C2H2O , which has a carbon‑carbon double bond. Include all hydrogen atoms and show all unshar
Vladimir79 [104]

<u>Answer:</u> The lewis dot structure is attached below.

<u>Explanation:</u>

A Lewis dot structure is defined as the representation of atoms having electrons around the atom where electrons are represented as dots.

A ketene is an organic compound having general formula R′R″C=C=O, where R and R' are two different/same monovalent chemical groups.

The given chemical compound having formula C_2H_2O is represented as H_2-C=C=O.

Total number of unshared electrons = 4 (left on oxygen atom only)

The lewis dot structure of C_2H_2O is given in the image below.
