Answer:
mNaNO3 =765g
Explanation:
First, we write the balanced chemical equation representing the chemical reaction that happened between aluminum nitrate and sodium chloride.
Balanced chemical equation:
AL(NO3)3+3NaCl ⟶ 3 NaNO3+AlCl3
According to the equation, each mole of aluminum nitrate requires three moles of sodium chloride. Thus, the required number of moles of sodium chloride is
4 Mol ⋅ 3 = 12mol
Based on the data provided in the table, there were 9 moles of sodium chloride used in the reaction, which was not enough for the entirety of aluminum nitrate to react. So, sodium chloride must have been the limiting reactant.
Therefore, we use the number of moles (n) of sodium chloride to calculate the number of moles of sodium nitrate, which has a 1:1 ratio with sodium chloride.
Number of moles sodium nitrate:
nNaNO3=nNaCl
nNaNO3 = 9 mol
We can also calculate the mass (m) of sodium nitrate that was produced by multiplying its number of moles by its molar mass (MM), 85.00g/mol.
Mass of sodium nitrate produced:
mNaNO3 = nNaNO3 ⋅ MMNaNO3
mNaNO3 = 9 mol ⋅ 85.00 g/mol
mNaNO3 =765g
Answer:
0.1105 moles per 130 ml
Explanation:
For 1 L (1000) of solution, no of moles are = 0.85
For 1 ml of solution, no of moles are = 0.85/1000 moles
For 130 ml of solution, no of moles are= 0.85/1000 x 130
= 0.1105 moles per 130 ml
Well in polymerization or in dehydration synthesis, the individual monomer molecules contain either H or OH attached to the end of their respective molecules. When they chemically compline together both the H and OH come off or break from their respective molecules and form water as a product. In place, a covalent bond is produced connecting the monomers together. In break down of polymers, with Water, the water molecule essentially disconnects the large molecule at the same place where it would have formed a covalent bond, and causes one of the monomers to bond to either a H and or OH. Separating the 2 compounds.
