<u>Answer:</u> The correct answer is it is a base because it increases the concentration of hydroxide ions.

<u>Explanation:</u>

An acid is defined as the chemical specie which donates hydrogen ion when dissolved in water.

HA(aq.)\rightarrow H^+(aq.)+A^-(aq.)

A base is defined as the chemical specie which donates hydroxide ion when dissolved in water.

BOH(aq.)\rightarrow B^+(aq.)+OH^-(aq.)

A salt is formed when an acid reacts with base. This is known as neutralization reaction.

NaOH is considered a base because it produces sodium and hydroxide ions when dissolved in water.

NaOH(aq.)\rightarrow Na^+(aq.)+OH^-(aq.)

Hence, the correct answer is it is a base because it increases the concentration of hydroxide ions.

The answer is; It is salt because it is formed by the reaction of an acid and a base.


Salt is composed of cations and anions (with a net charge of 0) joined together by ionic bonds attributed to their complementary charges. NaOH is an alkali salt because it forms an alkaline solution when dissolved in water – because it dissociates hydroxide ions.

Scientific notation of (4.5+ 17) x 104 -1.5 x 104
Naddik [55]

Answer:

4.5× 104 + 1.7× 105. Firstly, we need to ensure that both exponents have the same value. Thus, we need to change the value of 1.7 x 105 to 17 x 104. If both already had the same exponential value, you can neglect this step. 4.5× 104+ 17 × 104. Now, we will take exponentials common and add the decimal values. (4.5+ 17) × 104 | 21.5 × 104. Similar steps are taken for the subtraction phase we just need to retrace our steps and find differences rather than sums. These lessons and worksheets show you how to perform sums and differences with values that are in scientific notation.
