Law of Action and Reaction mean "To every action there is equal and opposite reaction.

Explanation:

It is Newtons third law which explained few things such as :-

1. The nature of the forces between the two interacting objects.

2. According to this law , the force that is exerted from Object-1 to Object-2 is said to be equal in magnitude and opposite to the direction to the force exerted to object 2 upon object 1.

3. Eaxmple - As we push against the wall - Action , the wall in return opposes equal force to resist the pressure of the hand - Reaction.

Define thermal and electrical conductivity, solubility, magnetism, melting and boiling points

Anon25 [30]

Answer:

thermal conductivity: the rate at which heat is transferred by conduction through a unit cross-section area of a material, when a temperature gradient exits perpendicular to the area

electrical conductivity: the measure of the amount of electrical current a material can carry or it's ability to carry a current

solubility: the ability to be dissolved, especially in water

magnetism: a physical phenomenon produced by the motion of electric charge, resulting in attractive and repulsive forces between objects

melting point: the temperature at which a given solid will melt.

boiling point: the temperature at which a liquid boils and turns to vapor

The equation below represents a double replacement/displacement reaction;

Naddik [55]

AB+XY->AY+XB
We know that the answer would be KCl because of the switching that takes place during a double displacement reaction. Just like Zn and MnO4 switched and combined, the remaining elements, K and Cl, will combine.
We know that the answer is simply KCl because both K and Cl have an ion of only +/-1, meaning when they cross, no suffixes are made, since their ions are only 1.
For example, if you combined Mg with Cl, you would get MgCl2, because Mg has an ion of +2.
I hope this helps!

1. A solution with a pH of 9 has a pOH of

Alecsey [184]

Answer:

strength = 10⁻²/10⁻³ = 10 times more acidic

Explanation:

1. A solution with a pH of 9 has a pOH of

pH + pOH = 14 => pOH = 14 - pH = 14 - 9 = 5

2. Which is more acidic, a solution with a pH of 6 or a pH of 4?

pH of 4 => Higher [H⁺] = 10⁻⁴M vs pH of 6 => [H⁺] = 10⁻⁶M

3. How many times more acidic is a solution with a pH of 2 than a solution with a pH of 3?

soln with pH = 2 => [H⁺] = 10⁻²M

soln with pH = 3 => [H⁺] = 10⁻³M

strength = 10⁻²/10⁻³ = 10 times more acidic

4. What is the hydrogen ion concentration [H + ] in a solution that has a pH of 8?

[H⁺] = 10^-pH = 10⁻⁸M

5. A solution has a pOH of 9.6. What is the pH? (Use the formula.)

pH + pOH = 14 => pH = 14 - 9.6 = 4.4
