According to VSEPR theory, what is the shape of a molecule of CS2? A bent B trigonal-planar C tetrahedral D linear
goblinko [34]

Answer:

D linear

Explanation:

Valence electrons of carbon = 4

Valence electrons of sulfur = 6

The total number of the valence electrons  = 4 + 2(6) = 16

The Lewis structure is drawn in such a way that the octet of each atom in the molecule is complete. So,

The Lewis structure is:

: \ddot S :: C:: \ddot S :

There is no lone pair involved, so, It is of type AB₂.

<em><u>According to the theory, the atoms will form a geometry in such a way that there is minimum repulsion and maximum stability. </u></em>

<em><u>So, it is of linear shape.</u></em>

What is the maximum number of hydrogen atoms that can be covalently bonded in a molecule containing two carbon atoms?
inessss [21]
Each carbon atom has 4 elections available for bonding. One of 2 of these are used for the C - C bond so there are 6 available to bond with hydrogen. So maximum number of hydrogen atoms = 6.

A sample of carbon dioxide at RTP is 0.50 dm3. How many grams of carbon dioxide do we have?
prohojiy [21]

Answer:

0.924 g

Explanation:

The following data were obtained from the question:

Volume of CO2 at RTP = 0.50 dm³

Mass of CO2 =?

Next, we shall determine the number of mole of CO2 that occupied 0.50 dm³ at RTP (room temperature and pressure). This can be obtained as follow:

1 mole of gas = 24 dm³ at RTP

Thus,

1 mole of CO2 occupies 24 dm³ at RTP.

Therefore, Xmol of CO2 will occupy 0.50 dm³ at RTP i.e

Xmol of CO2 = 0.5 /24

Xmol of CO2 = 0.021 mole

Thus, 0.021 mole of CO2 occupied 0.5 dm³ at RTP.

Finally, we shall determine the mass of CO2 as follow:

Mole of CO2 = 0.021 mole

Molar mass of CO2 = 12 + (2×16) = 13 + 32 = 44 g/mol

Mass of CO2 =?

Mole = mass /Molar mass

0.021 = mass of CO2 /44

Cross multiply

Mass of CO2 = 0.021 × 44

Mass of CO2 = 0.924 g.
