Answer:

Option A. 66 g

Explanation:

We'll begin by writing the balanced equation for the reaction. This is given below:

CH₄ + 2O₂ —> CO₂ + 2H₂O

Next, we shall determine the mass of CH₄ that reacted and the mass of CO₂ produced from the balanced equation. This is illustrated below:

Molar mass of CH₄ = 12 + (4×1)

= 12 + 4 = 16 g/mol

Mass of CH₄ from the balanced equation = 1 × 16 = 16 g

Molar mass of CO₂ = 12 + (16×2)

= 12 + 32 = 44 g/mol

Mass of CO₂ from the balanced equation = 1 × 44 = 44 g

SUMMARY:

From the balanced equation above,

16 g of CH₄ reacted to produce 44 g of CO₂.

Finally, we shall determine the theoretical yield of CO₂. this can be obtained as follow:

From the balanced equation above,

16 g of CH₄ reacted to produce 44 g of CO₂.

Therefore, 24 g of CH₄ will react to produce = (24 × 44) /16 = 66 g of CO₂.

Thus, the theoretical yield of CO₂ 66 g

The ksp of lead(ii) hydroxide, pb(oh)2, is 1.43 × 10-20. calculate the solubility of this compound in g/l.
antiseptic1488 [7]
When Pb(OH)₂ dissolves it dissociates as follows;
Pb(OH)₂ ---> Pb²⁺ + 2OH⁻
molar solubility is the number of moles of compound that can be dissolved in 1 L of solution.
if molar solubility of Pb(OH)₂ is x then molar solubility of Pb²⁺ is x and OH⁻ is 2x
the formula for solubility product constant is as follows;
ksp = [Pb²⁺][OH⁻]²
ksp = (x)(2x)²
ksp = 4x³
ksp = 1.43 x 10⁻²⁰
4x³ = 1.43 x 10⁻²⁰
x = 1.53 x 10⁻⁷ M
molar solubility of Pb(OH)₂ is 1.53 x 10⁻⁷ M
molar mass is 241.2 g/mol 
solubility of Pb(OH)₂ is 1.53 x 10⁻⁷ M x 241.2 g/mol = 3.69 x 10⁻⁵ g/L

Draw the curved arrow mechanism for the addition of HCN in water with NaOH to 3,4-dimethylcyclopentan-1-one to give the correspo
Crank

Answer:

See picture and explanation below

Explanation:

In the attached picture you have the answer for this.

In the first step, we have an acid base reaction between HCN and NaOH. When this happens, its formed the following:

HCN + NaOH --------> CN⁻ + H₂O + Na⁺

As a second step, The CN⁻ attacks the carbonile group in the cyclopentane. This causes to open the double bond, and then, the Cyano enters the molecule.

The final step is another acid base reaction, where the oxygen substracts a hydrogen atom of the water in the medium, and then, the alcohol group is formed. With this step, the cyanohydrin is finally formed. See the mechanism below in the picture.

Hope this helps

Why is it not possible to directly count the number of particles in a mole?
SVETLANKA909090 [29]

Answer: because a mole is based on Avogrado's number,  which is 6.02 x 10²³ particles. It isn't possible to directly count that many particles at a time.
