POH value was calculated by the negative logarithm of hydroxide ion concentration.
To know the hydrogen ion concentration, we need to know the pH value, that can be found out if pOH is known 
pH + pOH = 14
pH = 14 - pOH 
pH = 10.65
once the pH is known we have to find the antilog. 
[H⁺] = antilog (-pH)
antilog can be found by 
[H⁺] = 10^(-10.65)
[H⁺] = 2.2 x 10⁻¹¹ M

When explaining chemical reactions to a friend, Brianna models a reaction by taking several colors of modeling clay and making a
Ludmilka [50]

Answer:

True

Explanation:

A synthesis reaction is one that involves the combination of more than one reactants to form a single product. This is directly opposite to a decomposition reaction where a complex compound is broken down into various products.

Examples of synthesis reaction are;

1. The combination of sodium with chlorine to form sodium chloride.

2. The combination of hydrogen and oxygen to form water

so explaining what Brianna did, the models of clay are the reactants coming together to form a single product which is the sculpture.

What is one use for halogens?
Ahat [919]

The correct answer is D. Light bulbs

Explanation:

In chemistry, halogens are a group of elements characterized for being non-metallic elements (they cannot conduct heat or electricity), and for forming salts. In terms of uses, halogens had been used mainly as part of disinfectants, as well as, in the production of light bulbs and lamps. This last application implies small quantities of halogens such as iodine are used in the mechanism of bulbs or lamps and this is a better option than other elements as it increases the life of the bulb and makes bulbs to a whither color. According to this, one use of halogens is light bulbs.

Explain how a redox reacation involves electrons in the same way that a neutralization reaction involves protons
lidiya [134]
For the neutralization process: an acid acts as a donor and donates protons to the base. On the other hand, the base acts as an acceptor and accepts the transferred protons. In a nutshell, neutralization is mainly proton transfer process.

As for the redox process: the oxidized material usually transfers electrons to the reduced material. In a nutshell, redox is mainly electron transfer process.
