(3.5mol)(24.106 g/1mol c6h6) =84.371 g C6H6
Answer is: B. Hydroxide ions.
An Arrhenius base is a substance that dissociates in water to form hydroxide ions (OH⁻).
For example sodium hydroxide: NaOH(aq) → Na⁺(aq) + OH⁻(aq).
Another example, balanced chemical reaction: Ba(OH)₂(aq) → Ba²⁺(aq) + 2OH⁻(aq).
According to the Arrhenius definition barium hydroxide is base.
Acids and bases when react (neutralisation) produce salt and water.

Answer:
The law of conservation of mass states that mass in an isolated system is neither created nor destroyed by chemical reactions or physical transformations. According to the law of conservation of mass, the mass of the products in a chemical reaction must equal the mass of the reactants.
Explanation:
How does the concept of conservation of mass apply to chemical reactions? the reactants and products have exactly the same atoms. the reactants and products have exactly the same molecules. the change in the amount of matter is equal to the change in energy.
can someone help me with my qustions?
Answer:
The new pressure will increase.
Explanation:
If the temperature in a tank increases, the pressure inside the tank will also increase. This is one of the postulates of the general gas law.
Pressure exerted by a gas is it's force per unit area.
- When we reduce the equation of the combined gas law taking the number of moles to be 1, we see that;
"at constant volume, the pressure of a given mass or mole of gas varies directly with the absolute temperature" .
The higher the pressure, the higher the temperature will be.
Since the complete parameters are not given, use this expression below:
where P and T are pressure and temperature
1 and 2 represents initial and final states.
