Answer:
O
Explanation:
O is in the red which says nonmetal
Answer:
The concentration of Hydrogen Cation is:
Pure water is<u> NEUTRAL</u>
Explanation:
pH = It is negative logarithm of activity of Hydrogen ions.
Activity = concentration for dilute solutions
There are three types of solution based on pH:
1. Acidic solution : Those solution which have pH between 0 to 7 or less than 7 are acidic in nature . They turns blue litmus red.They contain more H+ ions than OH- ions
2. Basic : Those solution which have pH value greater that 7 of between 7 to 14 are basic in nature . They turn red litmus blue.They contain more OH- ions then H+ ions
3 . Neutral : Those solution which have pH = 7 are neutral . They are neither acidic nor basic in nature .They have equa;l concentration of H+ and OH- ions in the solution.
The given water has pH = 7 .This means it is neutral and has low H+ ion concentration in solution. The H+ ion are :
M in water.
OH- =
M in water
So overall neutral
Because the atom is neutral, it has no charge. For this to happen, the number of positive and negative charges must be the same. Therefore, because there are 11 -1 charged electrons, there must also be 11 +1 charged protons
So the answer is (2)
It is false that if a question is asking about an opinion, it can be answered with science.
<h3>What is opinion?</h3>
A personal belief or assumed that is not tested or backed up by evidence is described as an opinion.
A hypothesis is typically a claim based on some form of observation or evidence. Hypotheses must be testable and, once tested, evidence-supported.
Any question that is based on opinion cannot be answered by scientific reasonings as it is not evidence based.
Thus, the given statement is false.
