Which formula represents an electrolyte? (1) CH3OCH3 (3) CH3COOH (2) CH3OH (4) C2H5CHO

2 answers:

3 0

(3) CH3COOH is the correct answer.

CH3COOH is a weak electrolyte. When being put in water, it separates into CH3COO- and H+, then the ions combine to form again CH3COOH. The process takes place back and forth.

Hope this would help~

Answer: The correct answer is Option 3.

Explanation:

Electrolyte is defined as a substance which dissociates into its ions in a solution and has a capacity to conduct electricity.

From the given options:

Option 1: $CH_3OCH_3$

This compound belongs to ether group and it does not form ions when present in a solution. Thus, it is not considered as an electrolyte.

Option 2: $CH_3OH$

This compound is an alcohol and it dissociates into its ion but the ions formed are not stable. Hence, it is not considered as an electrolyte.

Option 3: $CH_3COOH$

This compound is a carboxylic acid and it dissociates into its ion. The ions formed or the conjugate base formed are stable. Hence, it is considered as an electrolyte.

$CH_3COOH\rightarrow CH_3COO^-+H^+$

Option 4: $C_2H_5CHO$

This compound is an aldehyde and it does not form ions when present in a solution. Thus, it is not considered as an electrolyte.

From the above information, the correct answer is Option 3.

Can a combination reaction be a redox reaction ?

saul85 [17]

Answer:

Yes A redox reaction can be a combination reaction.

Two elements are mixed in a combination reaction to produce a single product.

Explanation:

Example: water formula

2H2 + O2 → 2H2O

Oxygen is reduced in this reaction when electrons are transferred from hydrogen to oxygen and hydrogen is also oxidized since oxygen from hydrogen accepts electrons. Oxygen is the oxidizing agent and hydrogen is the reducing agent.

2H2 + O2 → 2H2O

list the four quantum numbers from LAST electron of each of the following elements in their ground state: sodium, nitrogen, oxyg

Rasek [7]

Explanation:

The four quantum numbers gives the position of the orbital, its spatial orientation, the shape of the orbital and the spin of the an electron in the orbital.

The principal quantum number(n) gives the main energy level in which the orbital is located; n = 1,2,3,4....

Azimuthal or secondary quantum number (l) gives the shape of the orbitals an they take values l = 0,1,2,3.... and their names are s for 0, p for 1, d for 2 and f for 3.

Magnetic quantum number gives the spatial orientation or degeneracy of the orbitals in the subshell.

Spin quantum number gives the spinning of the electrons

Electronic configuration:

Na = 1s² 2s² 2p⁶ 3s¹

The last electron enters the 3s¹

n = 3

l = 0

m = 0

spin =+ or - $\frac{1}{2}$

N = 1s² 2s² 2p³

last electron enters 2p³

n = 2

l = 1

m = -1, 0, 1

spin = + or - $\frac{1}{2}$

O = 1s² 2s² 2p²

last electron enters 2p²

n = 2

l = 1

m = -1, 0, 1

spin = + or - $\frac{1}{2}$

Cl =1s² 2s² 2p⁶ 3s² 3p⁵

last electron enters 3p⁵

n = 3

l = 1

m = -1, 0, 1

spin = + or - $\frac{1}{2}$

S = 1s² 2s² 2p⁶ 3s² 3p⁴

last electron enters 3p⁴

n = 3

l = 1

m = -1, 0, 1

spin = + or - $\frac{1}{2}$

How many grams of Al(no2)3 should be added to 1.3L of water to prepare a 2.0M solution

Virty [35]

Answer: 429 grams of $Al(NO_2)_3$ should be added to 1.3 L of water to prepare 2.0 M solution

Explanation:

Molarity of a solution is defined as the number of moles of solute dissolved per Liter of the solution.

$Molarity=\frac{n}{V_s}$

where,

n = moles of solute $Al(NO_2)_3$ = $\frac{\text {given mass}}{\text {Molar mass}}=\frac{xg}{165g/mol}$

$V_s$ = volume of solution in Liters

Now put all the given values in the formula of molarity, we get

$2.0M=\frac{xg}{165g/mol\times 1.3L}$

$x=429g$

Therefore, 429 grams of $Al(NO_2)_3$ should be added to 1.3 L of water to prepare 2.0 M solution
