Answer:
option c
Explanation:
Solution is formed when a solute is dissolved a solvent.
Formation of solution is decided by the interaction between solute and solvent.
When a solute is dissolved, the intermolecular interactions in between solute molecules are broken. And New interactions are formed between solute and solvent.
In order to form solution, the solute-solvent interactions must be stronger than solute-solute and solvent-solvent in interactions.
Therefore, among given the option c is correct.
The balanced reaction shows for every 2 Aluminum we need 3 Chloride gas.
20 Al * (3 Cl / 2 Al) = 30 Cl
We have 45 Cl ... Which is more than enough for 20 Al
We have excess Cl
Then the limiting reagent = Al
The formula for the monoprotic acid is taken as HA, reaction with base is as follows;
HA + NaOH ---> NaA + H₂O
Stoichiometry of acid to base is 1:1
At the neutralisation point, number of HA moles = number of base moles
Number of NaOH moles reacted = 0.100M / 1000 mL /L x 30.0 mL = 0.003 mol
Therefore number of HA moles reacted = 0.003 mol
the mass of acid 0.384 g
Therefore molar mass - 0.384 g/ 0.003 mol = 128 g/mol
Answer:
This question is incomplete
Explanation:
This question is incomplete because of the absence of options. However, the compound C₆H₁₄ is hexane. Hexane is a member of saturated hydrocarbons (homologous series) called alkanes (with the general formula CₙH₂ₙ₊₂). The structure for an hexane is shown below
H H H H H H
I I I I I I
H - C - C - C - C - C - C - H
I I I I I I
H H H H H H
which can also be written as
CH₃CH₂CH₂CH₂CH₂CH₃
Answer:
1 Oxygen atom has a mass of 16 grams, thus diatomic oxygen weights twice as much- 32 grams. Hence 32 grams is needed.
