The concentration of hydrogen can be shown as:
[H+ ] = 3 * 10-5 M
pH can be determined as:
pH = - log [H+ ]
= - log (3 * 10-5)
= 4.53
Thus the pH of solution is 4.53
Answer: different charges but same mass
protons and neutrons determine the mass (electrons are too light)
since atom q and atom r are of the same proton and neutron , they are of the same mass
protons and electrons determine the charge
a proton has a 1+ and electron has a 1- charge
atom q has no charge, the protons and electrons cancel each other out
atom r has a 1- charge as there is one more electron than proton.
Answer:
Covalent bonding occurs when electrons are shared between atoms. Double and triple covalent bonds occur when four or six electrons are shared between two atoms, and they are indicated in Lewis structures by drawing two or three lines connecting one atom to another.
