Answer:
the left side are the reactants and the right side is the products
Explanation:
The reactants are the elemental compounds that are being turned into the product
Answer: The molar solubility of in a solution that is buffered at ph 8.00 is 0.19 M
Explanation:
Solubility product is defined as the equilibrium constant in which a solid ionic compound is dissolved to produce its ions in solution. It is represented as
We are given:
Solubility product of =
The equation for the ionization of the is given as:
1 mole of gives 1 mole of and 2 moles of
Given : pH = 8.00
Thus the molar solubility of in a solution that is buffered at ph 8.00 is 0.19 M
Answer:
Sample C has the highest density
Explanation:
Step 1: data given
Sample A has a mass of 224.96 grams
Sample B has a mass of 0.55632 lbs = 252.3425 grams
Sample C has a mass of 0.30648 kg = 306.48 grams
The volume is for all the sample equal
Step 2: Calculate density
We suppose the volume is 1000 mL
Density = mass / volume
Density sample A = 224.96 grams / 1000 mL = 0.22496 g/mL
Density sample B = 252.3425 grams / 1000 mL = 0.2523425 g/mL
Density sample C = 306.48 grams / 1000 mL = 0.30648 g/mL
Sample C has the highest density
Answer:
Explanation:
in a combustion of ethane 2 moles of ethane react with 7 moles of O2
now no of moles in 54 gram of O2=mass/ molar mass
moles =54/32=1.7 moles
if 7 moles of O2 required 2 moles of ethane then 1.7 mole required=?
7 moles of O2=2 moles of C2H6
1.7 moles of O2=1.7*2/7=0.5 moles of C2H6
0.5 moles of C2H6 contain how much grams=?
mass= moles*molar mass=0.5*30=15
