Answer:
0.0123 moles
Explanation:
Concentration = Moles / Volume of solution
or you can rearrange the formula to get
Moles = concentration (moles/liter) x volume of solution (liter)
First convert your volume to L instead of mL. 35mL = 0.035L
moles = 0.350 moles/liter x 0.035 liter (liters cancel out)
moles = 0.0123
No because the second atom has 1 more neutron and 2 more electrons.
Answer:
The number of atoms present does not affects the half-life
Explanation:
The half-life, of an unstable atomic nuclei is the duration in time for the quantity of the atoms having such unstable nuclear to decrease by a factor of 2 in nature. Here nature refers to the position of the unstable nuclear in the environment. It is indicative of the rate of decay of unstable atoms and the period of survival of stable atoms
The half life is given by
Therefore,
Whereby as time time increases N₀ becomes larger such that remain constant.
Yes they do if they have the same parent/s
C . is a compound. So I would say that CH4 is not binary compound because that’s methane’s formula
