Answer:
The cost is $0.063.
Explanation:
First, we need to express the volume of the hangar in liters. We know that 1 ft³ = 28.31 L, so using proportions:
The amount of vanillin required would be:
Finally, the price for such amount of vanillin is:
Answer:
d- it is an acid because it increases the concentration of hydronium ions
Explanation:
HCl; hydrochloric acid is an acid because it increases the concentration of hydronium ions when in solutions.
An acid is a substance that interacts with water to produce excess hydroxonium ions H₃O⁺ in an aqueous solution.
For example:
HCl + H₂O → H₃O⁺ + Cl⁻
HCl is classified as a strong acid due to its complete ionization when in solutions.
First we must write a balanced chemical equation for this reaction
The mole ratio for the reaction between 
and 
is 1:2. This means 1 moles of will neutralize 2 moles . Now we find the moles of each reactant based on the mass and molar mass.
The was enough to neutralize the acid because 18.87:39.67 is the same as 1:2 mol ratio.
The answer is C.
The vast difference in electronegativity of the oxygen and hydrogen in water, the O-H bond is polar.
