<span>1 mole of any substance contains 6.02 x 10^23 particles.
Hence 0.25 mole of any has will contain 0.25 x 6.02 x 10^23 molecules of that gas
They cannot contain the same no. of atoms as 1 molecule of CO2 contains 3 atoms, 1 molecule H2 contains 2 molecules, and 1 molecule of NH3 contain 4 atoms
1 molecule of any gas will occupy 22.4 L at STP
hence 0.25 mol of all of these gases accupy the same volume
all of these molecules have different molar masses. thus their g.f.w cannot be same
Your answer is that they will occupy the same volume, and the same number of molecules</span>
There are two in the first ring leaving only six out of eight to go on the next
The concentration of reactants decreases and the concentration of products increases. :)
There is only 1 negative choice here, so you can solve by common sense.
C. They reproduce slower than unicellular organisms.
This is true because, for example, think of humans. We take 9 months to reproduce uses multiple stages of meiosis. Unicellular organisms on the other hand, such as bacteria, are asexual and use binary fission to reproduce, which happens very quickly, but creates less diversity.
<span>Zn⁰(s) + CuSO4(aq) --> Zn²⁺SO4²⁻(aq) + Cu(s)
</span>Zn⁰ --- in free elements oxidation number is 0.
Zn²⁺SO4²⁻ ---- ionic compound , it has ion Zn²⁺, so oxidation number here is +2.
<span>The oxidation number of Zn changes from 0 to +2.</span>
