Nitric acid (HNO3) and potassium hydroxide (KOH) combine in a neutralization reaction to form water and a salt. Which of the following correctly identifies the salt that is produced? OHK NOK2 KNO3 HOH

The answer to your question is KNO₃

Explanation:

Data

HNO₃

KOH

neutralization reaction

Process

1.- In a neutralization reaction an acid reacts with an alkali and the products are water and a binary or ternary salt.

Reactants             acid = HNO₃      alkali = KOH

A neutralization reaction is a double displacement reaction so the salt formed is.

                   HNO₃  +  KOH  ⇒   H₂O  + KNO₃

Potassium nitrate

a sonic boom is a loud boom that breaks the sound barrier

explanation:

it is given that trillions of microbes make up to 1% to 3% of the body mass.

let's take average of this percentage: 2%

consider the average mass of the human body as 70 kg.

then, trillions of microbes would have mass  

therefore, 100 trillion micro-organisms would weigh:

this is an approximate value and could change depending on the mass of the human body and percentage of the microbes present in it.

average mass per microorganism =
