Uhhh, that looks like a game. I don't know how to tell u the answers for that thing -_-
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.

60
Explanation:
The number of electrons in an atom of Q-95 will be 60 electrons.
The atomic number of an atom is the number of protons in the atom of the isotope
This number is unique to every atom and their isotope
An isotope of an atom is the existence of an atom having the same atomic number but different mass numbers.
Since atomic number the same as number of protons, they are the positively charged particles in an atom.
To have a negative charge, the number of electrons must be more than that of protons.
Charge = number of protons - number electrons
charge = -1
-1 = 59 - number of electrons
Number of electrons = 60 electrons

A chemical reagent that is used in this experiment is silver nitrate (AgNO3). It is used to distinguish calcium chloride and calcium carbonate. when this reagent is used, silver from silver nitrate reacts with Chloride to calcium chloride and forms silver chloride, making a precipitates of white color.
