Answer:
C₄F₈
Explanation:
Using their mole ratio to compute their mass
molar mass of carbon = 12.0107 g/mol
molar mass of fluorine gas = 37.99681
let x = mass of carbon
given mass of fluorine = 1.70 g
x / 12.01067 = 1.70 / 37.99687
cross multiply
x = ( 1.70 × 12) / 37.99687 = 20.4 / 37.99687 = 0.53688 g
mass of one mole of CF₂ = 0.53688 + 1.70 = 2.23688 g
number of mole of CF₂ = 8.93 g / 2.23688 = 3.992 approx 4
molecular formula of CF₂ = 4 (CF₂) = C₄F₈
A.
This is because BaSO₄ has the lowest solubility product out of all the substances.

Answer:red green and blue hope it helps!,!!!!!!!
Explanation:
Answer:
a) 2.91%
b) 90.5 grams
Explanation:
Mass percentage is
mass%=
a) the mass of NaCl = 1.50g
The mass of water = 50.0 g
Total mass =1.5+50=51.50 g
mass% = 
%
b) the mass percent of NaOCl = 3.62 %
It means the mass of NaOCl in 100g of bleaching solution 3.62 g
so mass of NaOCl in 2.50kg = 0.0905 kg = 90.5g
