which of the following is an arrhenius acid? a brønsted–lowry acid? a lewis acid? it is possible for an acid to be of more than one type.

Answers

Answer 1

Answer:

Arrhenius acids are substances which produces hydrogen ions in solution, Arrhenius bases are substances which produces hydroxide ions in solution. A Bronsted-Lowry acid is a proton donor (usually hydrogen ion). And a Bronsted-Lowry base is a proton acceptor (usually hydrogen ion). Consider a chemical reaction between HCl and NaOH. We have the reaction HCl + NaOH à NaCl + H2O. The hydroxide ions in the NaOH are bases because they accept hydrogen ions from acids to form water. And an acid produces hydrogen ions in solution by giving a proton to the water molecule. Therefore, the answer is d. a Bronsted-Lowry base.

A buffering solution consists of both strong acids and bases.
a. True
b. False

Answers

False. A buffering solution consists of a WEAK acid such as CH3COOH, C5H5N, or ammonia. A buffering solution resists pH change upon the addition of an acidic or basic components. It can neutralize little amounts of added acid or base, thus maintaining the pH of the solution relatively stable. The correct answer is letter "B. false"

Answers

A piece of sodium metal can be described as a soft silvery white metal that is highly reactive and can sometimes cause explosions. This is the reason why it doesn't occur naturally as an isolated metal. Instead, different sodium containing compounds undergo different processes to isolate the sodium metal.

The atomic number of an atom will always identify the amount of protons in its nucleus. If the atom is neutral, what else is identified by the atomic number? A. the number of neutrons in the atom B. the most common isotope of the atom C. the atomic mass of the atom D. the number of electrons in the atom

Answers

D.The number of electrons in an atom.In an atom,the number of protons and electrons are always the same which is indicated by the atomic number.Since we know that protons have a positive charge, and electrons have a negative charge this suggests that an atom is always neutral as +1-1=0.
