Answer:
The molarity of the acid HX is 6.0 M.
Explanation:
We determine the amount of moles of KOH used to neutralize the acid:
=0.12 moles KOH
Then, we calculate the amount of moles of acid:
0.12 moles KOH×=0.12 moles HX
The molarity of HX is:
=6.0 M
Use the coefficients in front of each element or compound
in this case 2 1 2
Answer: The answer is MEDUIM
Explanation:
Answer: The atom has three components the electrons, neutrons and protons.
Explanation:
J.J Thomson is responsible for the discovery of electron. He discovered the electrons while determining the properties of cathode rays in 1897. Rutherford is responsible for the discovery of proton during 1909 while performing the gold foil experiment. W. Bothe and H. Becker is credited to the discovery of neutrons.
