Answer:
They are atoms that make up a subatomic particle
Explanation:
Atoms are made up of protons, neutrons and electrons, also known as subatomic particles. Because an atom is neutral, the number of electrons is equal to the number of protons. Electrons circle the nucleus, which is made up of protons and neutrons.
Answer:
4CHO + 3O2 → 4CO2 + 2H2O
Explanation:
4CHO + 3O2 → 4CO2 + 2H2O
Not sure how to explain but I hope this helps :)
The concentration of each of the individual ions in a 0750 M Ba(OH)2 solution is
[Ba2+] = 0.750 M
[OH-]= 1.50 M
<h3>
calculation</h3>
write the equation for dissociation
that is Ba(OH)2 (s)→ Ba2+(aq) + 2OH-(aq)
by use of mole ratio of Ba(OH)2 : Ba2+ which is 1: 1 the concentration of Ba2+ is therefore= 0.750M
by use of mole ratio of Ba(OH)2 : OH- which is 1:2 the concentration of OH- =0.750 M x2/1=1.50 M
