Answer:

[OH⁻] = 10⁻¹⁴/[H⁺].

Explanation:

∵ [H⁺][OH⁻] = 10⁻¹⁴.

<em>∴ [OH⁻] = 10⁻¹⁴/[H⁺].</em>

Answer:

Kw = [H+][OH-]

Explanation:

For a given solution H+ refers to the hydrogen ion concentration and is indicative of the acidity of the solution. The more the [H+] concentration, higher is the acidity. Similarly, OH- refers to the hydroxide ion concentration and reflects the basicity of the solution. A solution with a higher OH- concentration is said to be basic.

The two are related by considering the dissociation of water:

H2O(l)\rightleftharpoons H+(aq)+ OH-(aq)

The dissociation constant for water, Kw is:

Kw = [H+][OH-]\\\\where\ Kw = 10^{-14} \\\\10^{-14} = [H+][OH-]\\

[H+] = \frac{10^{-14}}{[OH-]}

instrucions classify the following reactions as synthesis, decomposition,single replacement, double replacement, or combustion.
My name is Ann [436]

Answer:

There are no specific equations but here what i can give you:

1. Synthesis -- A synthesis reaction is a chemical change in which two or more substances react to form a single new substance.

In all synthesis reactions, there is a single product that is a compound!

2. Decomposition -- A decomposition reaction is a chemical change in which a single compound breaks down into two or more simpler products. (This is the opposite of synthesis reactions!)

Most decomposition reactions require energy in the form of heat, light, and electricity.

3. Single Replacement -- A single-replacement reaction is a chemical change in which one element replaces a second element in a compound. You can identify a single-replacement reaction by noting that both the reactants and the products consist of an element and a compound.

4. Double Replacement -- A double-replacement reaction is a chemical change involving an exchange of positive ions between two compounds.

For a double replacement reactions to occur, one of the following is usually true:

- One of the products is only slightly soluble and precipitates from solutions.

- One of the products is a gas.

- One product is a molecular compound such as water.

5. Combustion -- A combustion reactions is a chemical change in which an element or a compound reacts with oxygen, often producing energy in the form of heat or light.

A combustion reactant always involves oxygen as a reactant. (If the supply of oxygen is limited, then the combustion will not be complete.)

The other reactant is a hydrocarbon, which is a compound composed of hydrogen and carbon and the complete combustion of a hydrocarbon produces CO2 and H2O.

Hydrocarbons include methane, propane, and butane.

I really hope this helps you!
