Answer:
That is the correct form for a hypothesis.
Explanation:
Answer:
In 1000 ml there is 0.10 moles of Fe 2+
Therefore, in 10 ml there is (0.1/1000)*10= 0.001 mol of Fe2+
mole ratio for rxn Fe2+ : MnO4- is
1 : 2
therefore if 0.001 moles of Fe2+ react then 0.001*2 =0.002 moles of MnO4- react with Fe2+
hence, molarity of MnO4- = (mol*vol)/1000
= 0.002*10.75/1000= 2.15*10-5M

Answer:
The number of each element in the molecule.
Explanation:
C₁₂H₂₂O₁₁ is one molecule, and it is made 3 elements carbon, hydrogen, and oxygen. There are 12 carbons, 22 hydrogens, and 11 oxygens. If these numbers were different, it would be a different molecule.
Ionic substances produce ions in solution while molecular substances produce molecules in solution.
<h3>What is a solution?</h3>
A solution is a combination of solute and solvent. The species that occur in solution depends on the type of substance that was dissolved. Since the table is not shown, we do not know exactly what compounds were dissolved in solution.
Generally, if an ionic substance is dissolved in solutions that ions are present in the solution. If a molecular substance is dissolved in solution, molecules are present in solution.
