Which type of orbitals overlap to form the sigma bond between c and cl in ch3cl?

1 answer:

3 0

<span>The hybridization between c and cl in ch3cl is sp3-sp3 because it will maximize the electron distribution in cl.in ch3cl carbon is considered to be sp3 hybridized.the ch3cl molecule is assumed to be tetrahydral in shape with bond angles in the neighborhoodof 109.5 degrees.The cl has sp3 hybridization due to the four pairs of electrons.</span>

Consider this reaction. What volume of oxygen gas, in milliliters, is required to react with 0.640 g of SO2 gas at S TP? 11.2 mL

DedPeter [7]

Answer:

112mL

Explanation:

We'll begin by calculating the number of mole in 0.640g of SO2.

This is illustrated below:

Molar mass of SO2 = 32 + (16x2) = 64g/mol

Mass of SO2 = 0.640g

Number of mole of SO2 =.?

Mole = mass /molar mass

Number of mole of SO2 = 0.640/64

Number of mole of SO2 = 0.01 mole

Next, we shall determine the number of mole of O2 required for the reaction. This is illustrated below:

2SO2(g) + O2(g) —> 2SO3(g)

From the balanced equation above,

2 moles of SO2 reacted with 1 mole of O2.

Therefore, 0.01 mole of SO2 will react with = (0.01 x 1)/2 = 0.005 mole of O2.

Therefore, 0.005 mole of O2 is required for the reaction.

Finally, we shall determine the volume of O2 required for the reaction as follow:

Note: 1 mole of a gas occupy 22.4L (22400mL) at stp.

1 mole of O2 occupy 22400mL at stp.

Therefore, 0.005 mole of O2 will occupy = 0.005 x 22400 = 112mL

Therefore, 112mL of O2 is required for the reaction.

How many grams of al2o3 (mm = 101. 96 g/mol) are produced when 91. 7 grams o2 reacts with excess aluminum?

Ronch [10]

Answer:

Explanation:

1. Write down the balanced equation

2. Use molar mass of O2 (32g/mol) divided by the given mass to derive the amount of mols

3. multiply the answer by 2/3 (divide by 3 then multiply by 2), to ensure the mols are in correct proportion

4. Use given molar mass and multiply it by the amount

5. Make sure to use proper significant digits (3 in this case) and units :)
