I have answered all 9/10 + this one so 10/10
Explanation:
Answer:
molality of sodium ions is 1.473 m
Explanation:
Molarity is moles of solute per litre of solution
Molality is moles of solute per kg of solvent.
The volume of solution = 1 L
The mass of solution = volume X density = 1000mL X 1.43 = 1430 grams
The mass of solute = moles X molar mass of sodium phosphate = 0.65X164
mass of solute = 106.6 grams
the mass of solvent = 1430 - 106.6 = 1323.4 grams = 1.3234 Kg
the molality = 
Thus molality of sodium phosphate is 0.491 m
Each sodium phosphate of molecule will give three sodium ions.
Thus molality of sodium ions = 3 X 0.491 = 1.473 m
The Earth's crust or is it the continental plates one of the two but they push against each other costing a tsunami.
Answer:
3–heptene or Hept–3–ene.
Explanation:
To name the compound given in the question above, we must determine the following:
1. Identify the functional group of the compound.
2. Locate the longest continuous carbon chain. This gives the parent name of the compound.
3. Identify the substituent group attached to the compound.
4. Locate the position of the double bond (i.e the functional group) by giving it the lowest possible count.
5. Combine the above to obtain the name of the compound.
Now, we shall obtain the name of the compound as follow:
1. The compound contains double bond. Hence the compound is an alkene.
2. The longest continuous carbon chain is 7 i.e heptene.
3. No substituent group is attached to the compound.
4. The double bond is located at carbon 3 since counting from the right gives the lowest count for the double bond.
5. The name of the compound is:
3–heptene or Hept–3–ene
