Answer:
x=2.8moles
Explanation:
first step balance the chemical equation
C2H6+O2-->CO2+2H2O
use more ratio to find the moles of water
1mole of C2H6= 2 moles of H2O
1.4mole of C2H6=?x
cross multiply
x=2.8 moles of H2O
It can be oxygen in only 1 atom. All elements on the periodic table can stand alone in one atom.
(I took a lucky guess, using some of my knowledge about elements )
When a change in PH = 10^-ΔPH
so the change = 10^-3.2
change depends on two factor 0.00063 (10^-3.2)and factor 1585 (10^3.2)depending on the way which the change goes.if PH change from PH=0 to PH= 3.2 so the change is decreasing from concentration from 1 mol to 0.00063 and if PH change from PH = 3.2 to PH=0 so the change is increasing by a factor of 1585.
B. False
Stability is determined by the ratio of neutrons and protons. Electrons are not in nucleus.
