Sharks are not extinct because they are on the endagered species list
Answer:
Because isotopes of the same element only differ by a few neutrons. An example is carbon-12 and carbon-14 isotopes which differ by 2 neutrons in their atomic nuclei.
Explanation:
Isotopes of the same element share the same chemical properties because they bear the same number of electrons (remember electrons are what are involved in chemical reactions). Therefore one can't use chemical methods to separate isotopes.
Separating isotopes require mechanical separation using ultra-high-speed centrifuges with very high-resolution power such that the little mass difference between the isotopes (due to differences in neutron numbers) can be used to separate them.

Answer:
pH = 2.5
Explanation:
Given data:
Concentration of HBr = 0.003 M
pH of solution = ?
Solution:
Formula:
pH = -log[H⁺]
by putting values,
pH = -log [ 0.003]
pH = 2.5

Answer:
Dispersion forces.
Explanation:
CO2 contains dispersion forces, and covalent bonds. It is a linear molecule, and the bond angle of O-C-O is 180 degree. O is more electronegative than C, the C-O contains polar bond with the having negative end pointing towards the O.
CO contains two C-O bonds. They cancel each other out because of the dipoles point in opposite directions. Although, CO2 contains polar bonds, it is known as a nonpolar molecule. So, the only intramolecular forces which CO2 having are London dispersion forces.
