Whats the ph of water

7

Explanation:

The pH of water is 7.

 pH is the convenient scale for expressing the level of acidity or alkalinity of aqueous solutions.

An acidic solution has a pH value less than 7.

As pH decreases, the acidity of solutions increases.

Neutral solutions have a pH of 7.

An alkaline solutions has a pH greater than 7 and the level of alkalinity increases as the pH increases.

  Water has a pH of 7 because the concentration of hydrogen and hydroxyl ion is equal.

explanation:

you can eliminate a, c, and d because they are questions based on opinions.

answer is: nuclear fusion produces elements that are heavier than helium.

nuclei combine to form a heavier nucleus, releasing energy.  

for example, fusion of hydrogen atoms at the sun.  

this fusion nuclear reaction is in the inner core of the sun and hydrogen (atomic number 1) is conveted into helium (atomic number 2).  

the inner core is the central region of the sun and all solar energy is produced in the core by nuclear fusion.
