What is the oxidation of KCL?

Chemistry
1 answer:
Assoli18 [71]4 years ago
3 0

Rules:

1) The oxidation number of a monatomic ion equals the charge of the ion.

2)The oxidation number of a Group 1 element in a compound is +1.

3) The oxidation number of a Group 17 element in a binary compound is -1.

4) The sum of the oxidation numbers of all the atoms in a neutral compound is 0.

KCl is an ionic compound. Consists of K+ ions and Cl- ions.

Oxidation of K= +1 (rules 1 and 2)

Oxidation of Cl= -1 (rules 1 and 3)

Rule 4 also applies-  +1 + (-1)= 0- a neutral compound

Hope this helps :)

vichka [17]

 

10% solution means=\frac{10g}{100mL}  

= \frac{0.1g}{1mL}  

= 100 mg/mL  

If the dentist inject 0.3 mL, that is equal to 0.3× 100 mg.

If the dentist inject 0.3 mL, that is equal to 30 mg.

So, as  anesthetic procaine hydrochloride is often used to deaden pain during dental surgery. the compound is packaged as a 10.% solution (by mass; d = 1.0 g/ml) in water. When our dentist injects 0.30 ml of the solution, 30 mg of procaine hydrochloride (in milligrams) is injected.

Calculate the volume of an
lions [1.4K]

Answer:

The formula for the volume of a solid rectangle is width x depth x height. Divide the volume by the product of the length and width to calculate the height of a rectangular object. For this example, the rectangular object has a length of 20, a width of 10 and a volume of 6,000.

Temka [501]

Answer:

C mechanical potential to chemical to mechanical kinetic

Explanation:

When the cheetah observes it prey, it does not move at all and remains still in one place. This is potential energy.

To chase after its prey or to pounce on it, the cheetah would require energy. This is obtained by its body by performing certain chemical activities that generate energy that help it to move.

When the cheetah finally undergoes this, it has enough energy to finally come out of hiding and chase its prey. This is kinetic energy as while doing so, the cheetah is in motion.

Hope it helps.

10.0 g of nickel is cooled to 2.0 °C and
Bas_tet [7]

Answer:

73.68 J

Explanation:

To find the energy absorbed by nickel, you need to use the following equation:

Q = mcΔT

In this equation,

-----> Q = energy (J)

-----> m = mass (g)

-----> c = specific heat (J/g°C)

-----> ΔT = change in temperature

The change in temperature is found by subtracting the initial temperature from the final temperature. You can plug the given values into the equation and simplify to find the energy absorbed.

m = 10.0 g

c = 0.120 J/g°C

ΔT = 63.4 °C - 2.0 °C = 61.4 °C

Q = mcΔT

Q = (10.0 g)(0.120 J/g°C)(61.4 °C)

Q = 73.68  J
