The presence of H3O+ is the hydronium ion, and one definition of an acid is something that donates a proton (H+). HCl in this case does just that. Basic solution forming with NaOH and water: ... NaOH + H2O ==>Na+ + OH- so it donates or produces OH- ions, thus making a basic solution
Fine particles, ground level ozone, sulfur dioxide, nitrogen dioxide, lead
Question:
What is the total combined mass of carbon dioxide and water that is produced?
Answer:
<u><em>109 kg</em></u>
Explanation:
When 23 kg of gasoline burns by consuming 86 kg oxygen, they produce carbon dioxide and water. To find the total combined mass of carbon dioxide and water, we will use mass conversation law.
According to mass conversation law, the mass of the product is equal to the mass of reagent.
Mass of reagent = Mass of product
In this reaction,
Gasoline + O2 → CO2 + H2O
23 kg + 86 kg → ?
23 kg + 86 kg = 109 kg
Combined mass of carbon dioxide and water will be 109 kg.

Because you always have to build off of other things to help make yours better and learn from the mistakes
Answer:10.0 mL of 0.00500 M phosphoric acid
Explanation:
If we look at the Ka values of the acids, we will realize that phosphoric acid has a Ka of 7.1 * 10-3. It is the only acid in the list having acid dissociation constant less than 1. This means that it does not ionize easily in solution and a very large volume of base must be added to ensure that it reacts completely. Acids with Ka >1 are generally regarded as strong acids. All the acids listed have Ka>1 except phosphoric acid.
