Answer:
<h3>The answer is 82.86 cm³</h3>
Explanation:
The volume of a substance when given the density and mass can be found by using the formula
From the question
mass of wood = 44 g
density = 0.531 g/cm³
It's volume is
We have the final answer as
<h3>82.86 cm³</h3>
Hope this helps you
C = covalent
I = Ionic
(I'm lazy to an extent)
An ionic bond is between a metal and a nonmetal, and a covalent bond is between 2 nonmetals.
H2 = C
Cl2 = C
O2 = C
HCl = C
LiF = I
NaCl = I
NaF = I
MgF = I
NH3 = C
CH4 = C
CO2 = C
NaP = I
N2 = C
NF3 = C
Answer: 7.29 g of 
will be produced from the given masses of both reactants.
Explanation:
To calculate the moles :
According to stoichiometry :
1 mole of 
require = 8 moles of 
Thus 0.0267 moles of will require=
of
Thus is the limiting reagent as it limits the formation of product and is the excess reagent.
As 1 mole of give = 8 moles of
Thus 0.0267 moles of give = of
Mass of 
Thus 7.29 g of will be produced from the given masses of both reactants.
The formula for chromium iii and sulfate ion is 2+3(1+4)= 2+(3x5)
