Answer:1. VSEPR theory

2. SP2

3. Sp3

Explanation: VSEPR means valence shell electron pair Repulsion. The theory states that, it is the nature of the valence electrons in a molecule that determines their shape. Lone pair of electrons create higher level of repulsion. The higher the level of lone pair present, Te higher Te distortion in shape which leads to lowering of bond angle.

Hybridization usually involves the 2s and 2p orbitals.

Hybrid orbital for boron is sp2 and for carbon is sp3

The reaction of 5.40 g of carbon with excess O2 yields 13.6 g of CO2. What is the percent yield of this reaction?

vazorg [7]

C + O2= CO2
$n = \frac{m}{mw}$
$n = \frac{5.4}{12} \\ n = 0.45 \: mol \: of \: carbon$
$n = \frac{13.6}{12 + 16 \times 2} \\ n = \frac{13.6}{44} \\ n = 0.31 \: mol \: of \: carbon \: dioxide$
CO2 is limit
5.4-3.72= 1.68 g of C is excess
5.4 g = 100%
3.72 g = x
x=68.9 %

for the given reaction, what volume of o2 would be required to react with 4.8 l of co , measured at the same temperature and pre

SVEN [57.7K]

We can see that 2 moles of The no react with 1 mole of O2 using this equation. 4.8 L NO x 1 L O2 / 2 L NO = 2.4 L of O2 are needed at constant pressure and temperature.

What is an example of pressure?

One can see a simple illustration of pressure by using a knife against a few fruit. If you press the flat side of the knife against the fruit, the top won't be cut. The force is spread more than a wide area (low pressure).

What are different types of pressure?

The physical pressure exerted to an object is referred to as pressure. Per unit area, a parallel force is applied to the surface of the objects. F/A (Force per Area) is the basic formula for pressure.
