Answer:
5mL of 6 M HCl is needed to make 100 mL of 0.3 M of HCl.
Explanation:
Using the dilution formula:
M1V1 = M2V2
M1 = 0.30 M
V1 = 100 mL
M2 = 6.0 M
V2 = unknown
Re-arranging the formula by making V2 the subject of the equation:
V2 = M1V1 / M2
V2 = 0.30 * 100 / 6
V2 = 5 mL
The volume of 6 M of HCl needed to make 0.3 M at 100 mL is 5 mL.

Answer:
Reactants: Ethanol (C₅H₅OH), Oxygen (O₂)
Products: Carbon dioxide (CO₂) and Water (H₂O)
Explanation:
Let’s rewrite each part of the described situation in chemical equation terms.
Ethanol - C₂H₅OH
is burned in the prescence of - +
oxygen - O₂
producing - →
carbon dioxide - CO₂
and - +
water - H₂O
Chemical equation:
C₂H₅OH + O₂ → CO₂ + H₂O
The terms on the left side of a chemical equation are reactants, and the terms on the right side of a chemical equation are products.
Therefore, since we know this, ethanol (C₂H₅OH) & oxygen (O₂) are the reactants, and carbon dioxide (CO₂) & water (H₂O) are the products.
