Answer:
Explanation:
The two carbon atoms would be different. These different carbon isotopes are called isotopes. Isotopy is the existence of two or more atoms of the same element having the same atomic number but different mass number due to the difference in the number of neutrons in their various nuclei.
Carbon for example has 3 known isotopes which are:
¹²₆C ¹³₆C ¹⁴₆C
These isotopes have different places in nature where they can be found. Some can occur together naturally.
Isotopes have the same chemical properties because they share similar electronic configuration.
Answer: ammonium bromide : acidic : The pH will be less than 7.
potassium cyanide : basic :The pH will be more than 7.
calcium nitrate: neutral : The pH will be approximately equal to 7.
calcium hypochlorite : basic :The pH will be more than 7.
Explanation:
pH is defined as the negative logarithm of hydrogen ion concentration. The scale ranges from 0 to 14.
When a solution is acidic, it will show a pH in the range of 0 - 6.9. When a solution is basic, it will show a pH in the range of 7.1 - 14. When a solution is neutral, it will show a pH of 7.
ammonium bromide :
: acidic as it is formed from the combination of strong acid HBr and weak base 
potassium cyanide :
: basic, as it is formed from the combination of weak acid HCN and strong base KOH
calcium nitrate:
: neutral, as it is formed from the combination of strong acid and strong base.
calcium hypochlorite :
: basic, as it is formed from the combination of weak acid
and strong base 
Answer:
Here
Explanation:
This is an acid-base reaction (neutralization): CaCO3 is a base, HCl is an acid.
