The gas flows from higher concentration/pressure to lower concentration/pressure, which is outside the ball.
Answer : It increases
Rusting is where oxygen binds to iron and forms iron oxide.
So once iron rusts, there is oxygen, just not in air; it's in the iron oxide.
All reactions are reversible, albeit at different rates (the "irreversible" ones are still reversible, but much slower given that they take so much collision luck and energy.
0001 M HCl is the same as saying that 1 *10-4 moles of H+ ions have been added to solution. The -log[. 0001] =4, so the pH of the solution =4.
Ethanoic acid ionizes in aqueous solutions to form two ions which are 
and 
<h3>Ionization of ethanoic acid</h3>
Ethanoic acid goes by the chemical formula 
.
In aqueous solutions, it ionizes as a monoprotic acid according to the following equation:
A monoprotic acid is an acid that is able to donate only a proton. Hence, ethanoic acid is said to be monoprotic because it ionizes in aqueous solutions to produce a single

Answer:
protons : 10
electron : 10
neutron : 10
Explanation:
Protons will usually be the same as the electrons when its a <u>Atom</u> (when its a ion or covalent bond or simple bond they will most likely be different)
the atomic number represents protons and electrons
the mass number - the atomic number = neutron
