We need more information to help please provide me with more information then @me when you do . ill be glad to help!
Answer:
Mass = 38.3 g
Explanation:
Given data:
Mass of Cl₂ required = ?
Mass of phosphorus = 10.6 g
Solution:
Chemical equation:
P₄ + 6Cl₂ → 4PCl₃
Number of moles of P₄:
Number of moles = mass/ molar mass
Number of moles = 10.6 g/123.9 g/mol
Number of moles = 0.09 mol
Now we will compare the moles of P₄ with Cl₂ from balance chemical equation.
P₄ : Cl₂
1 : 6
0.09 : 6×0.09 = 0.54 mol
Mass of chlorine gas:
Mass = number of moles × molar mass
Mass = 0.54 mol × 70.9 g/mol
Mass = 38.3 g
Answer:
see explanation and punch in the numbers yourself ( will be better for your test)
Explanation:
If you are given atoms you need to divide by Avogadro's number 6.022x10^23
then you will have moles of sulfur-- once you have moles multiply by the molar mass of sulfur to go from moles to grams
mm of sulfur is 32 g/mol
The activity of pure substance is taken as 1 because it has no effect on the reaction. Hence the equilibrium constant of the reaction is given by: <span>Ka=[H3O+][HCO1−3]/[H2CO3]. Hope this helps :)</span>
