Given the unbalanced equation below, how many moles

Svet_ta [14]

Answer: 6 mol Li

Explanation:

The first step is to balance the equation.

2Li+Cl₂⇒2LiCl

We would need our conversions to find the amount of moles of Li needed to produces 6 mol LiCl.

$6molLiCl*\frac{2molLi}{2molLiCl} =6molLi$

8. What was the original concentration in the BHL sample, if the dilution is 1:500 and the concentration 0.07 mg/ml

Yakvenalex [24]

Answer:

The original concentration is "35 mg/ml".

Explanation:

According to the question,

The solution is diluted,

= 1:50

The initial volume,

V1 = 1 ml

Final concentration,

= 0.07 mg

then,

The final volume,

V2 = 500 ml

As we know,

⇒ $V_1N_1=V_2N_2$

or,

⇒ $N_1=\frac{V_2N_2}{V_1}$

On substituting the values, we get

⇒ $=\frac{500\times 0.07}{1}$

⇒ $=\frac{35}{1}$

⇒ $=35 \ mg/ml$

Draw the Lewis structures for CH3OH, CH2O and HCOOH. Indicate the hybrid orbital used in the sigma bonds for each of the carbon

sdas [7]

Answer:

See figure 1

Explanation:

For this question, we have to remember that in the lewis structures all atoms must have 8 electrons. And each atom would have a different value of valence electrons:

Carbon => 4

Oxygen=> 6

Hydrogen=> 1

Additionally, for the hybridizations we have to remember that:

$Sp^3$ => 4 single bonds

$Sp^2$ => 1 double bond

$Sp^1$ => 1 double bond

With this in mind, the formaldehyde and formic acid would have $Sp^2$ carbons and the ethanol an $Sp^3$ carbon.

Finally, for the oxidation state. We have to remember that if we have more bonds with oxygen, we will have more oxidation. Therefore, the carbon that has more oxidation is the one in the formic acid (we have several bonds with oxygen).

See figure 1

I hope it helps!
