Answer: the pH moves to 0 on the pH scale
Explanation:
A base is defined as a substance which donates hydroxide ions when dissolved in water and an acid is defined as a substance which donates hydrogen ions in water.
Neutralisation reaction is defined as the chemical reaction in which an acid reacts with a base to produce a salt and water molecule. The ions from acid are neutralised by
ions from base.
Acids have pH ranging from 1 to 6.9, bases have pH ranging from 7.1 to 14 and neutral solutions have pH of 7.
Answer:
B.
Explanation:
The unit for rate is M/s while the unit for each molecule should be M. You can find the unit for k by putting the units for rate and the molecules into the equation
rate= k{X][Y]
M/s= k * *
k= (M/s) / ()
k=
You can also use this predetermined formula to solve this problem faster: k=
Where n is the number of molecule. There are 3 molecule(2X and 1Y) so n=3, so
k=
k= =
=
