The correct option is this: ACIDS DISSOLVE IN WATER TO PRODUCE A SOLUTION THAT REACT WITH METALS TO PRODUCE HYDROGEN GAS.

An acid refers to a chemical specie that is capable of donating protons or hydrogen ion and is also capable of accepting electrons. An acid can be described either as strong or weak acid depending on its degree of dissociation in water. A strong acid dissociates completely while a weak acid dissociates partially. When an acid dissociates in water, it yields cation and anions. When an acid react with metal, hydrogen gas and salt are usually formed.

A chemical engineer must report the average volume of a certain pollutant produced by the plants under her supervision. Here are

AfilCa [17]

Answer:

The chemical engineer should report average volume of 15.34 L.

Explanation:

Volume of Macon = 0.519 L

Volume of Allegheny = 44.67 L

Volume of Doheny = 0.826 L

Average of the volume of the pollutants:

$\frac{0.519 L+44.67 L+ 0.826L}{3}=\frac{46.015 L}{3}=15.33833 L$

The rule apply for the addition and subtraction is :

The least precise number present after the decimal point determines the number of significant figures in the answer.

Here the 44.67 has two significant digit after decimal point.So the answer will be reported as in with 2 significant figures after decimal point.

$15.33833 L\approx 15.34 L$

The chemical engineer should report average volume of 15.34 L.
