D. 18 as the elements in this group are the noble gases which exist as monoatomic elements with a full outer shell
Answer:
1. No; only a small percentage of mutations cause genetic disorders—most have no impact on health or development.
2. No. For example, some mutations alter a gene's DNA sequence but do not change the function of the protein made by the gene.
Explanation:
Here is a link to a website that explains these observed trends.

C14H30 because of the formula for alkanes:
CnC2n+2
Acid has a pH below 7 while water has a pH of 7. A strong acid with a pH of roughly 3, HCl is. Water gets more acidic and loses pH in the range of 4-5 when HCl is added to it.
<h3>What is pH?</h3>
A substance's pH is a gauge of how basic or acidic it is. It is a measurement of the amount of H+ present in the solution. It is equivalent to the negative logarithm of the concentration of H+ ions mathematically.
A solution is acidic if its pH value is less than 7, and basic if it is greater than 7. Acids have a lower pH because they contain more H+ ions. Strong acid hydrochloric acid has a pH between 2 and 3.
Water has no charge. Water becomes acidic in pH if any acid is introduced. Therefore, if HCl is given to water, the pH of the water will change to 3-5 depending on the acid content.
