Explanation:

The problem is in balancing the reaction equation;

Li + AlCl₃ → LiCl + Al

In balancing chemical equations, we must keep the law of conservation of matter in mind.

The law shows that the number of atoms on both sides of the reaction must be the same.

To balance the given equation, we set up simple, solvable algebraic mathematical expressions:

aLi + bAlCl₃ → cLiCl + dAl

Coefficients a, b,c and d

Conserving:

Li: a = c

Al: b = d

Cl: 3b = c

let b = 1;

d = 1

c = 3

a = 3

3Li + AlCl₃ → 3LiCl + Al

Which reagent is used to convert benzoyl to benzaldehyde?

solong [7]

Answer:

Hello dear,

● Benzene to benzaldehyde -

There are several ways to convert benzene into benzaldehyde.

1) Riemer-Tiemann reaction -

- In this reaction, benzene is converted to benzaldehyde with the help of CHCl3 & NaOH.

C6H6 ---> C6H5-CHO

Catalyst - CHCl3 & NaOH

2) Gatterman-Koch reaction -

- In this reaction, benzene is converted to benzaldehyde with the help of CO/HCl & AlCl3/CuCl.

C6H6 ---> C6H5-CHO

Catalyst - CO/HCl & AlCl3/CuCl

"The elementary reaction 2 NO2(g) → 2 NO(g) + O2(g) is second order in NO2 and the rate constant at 600 K is 6.77 × 10-1 M-1s-1.

blsea [12.9K]

Answer : The half-life at this temperature is, 3.28 s

Explanation :

To calculate the half-life for second order the expression will be:

$t_{1/2}=\frac{1}{k\times [A_o]}$

When,

$t_{1/2}$ = half-life = ?

$[A_o]$ = initial concentration = 0.45 M

k = rate constant = $6.77\times 10^{-1}M^{-1}s^{-1}$

Now put all the given values in the above formula, we get:

$t_{1/2}=\frac{1}{6.77\times 10^{-1}M^{-1}s^{-1}\times 0.45M}$

$t_{1/2}=3.28s$

Therefore, the half-life at this temperature is, 3.28 s

The compound CO2 is made of

Juliette [100K]

Explanation:

The compound $CO_{2}$ is also known as carbon dioxide. It is a gas. It forms when one carbon atom combines with two oxygen atoms.

This can be illustrated as follows.

$C(s) + \frac{1}{2}O_{2}(g) \rightarrow CO(g)$

$CO(g) + \frac{1}{2}O_{2}(g) \rightarrow CO_{2}$

Consumption of carbon dioxide gas in very low concentrations is not harmful but consumption of its large concentration is very harmful as it can affect the respiratory system.

Mama L [17]

Thermal energy, or heat, is the internal energy in substances; it is the vibration and movement of the atoms and molecules within a substance. The more thermal energy in a substance, the faster the atoms and molecules vibrate and move. Geothermal energy is an example of thermal energy.
