Given the balanced equation representing a reaction: HCl + H₂O → H₃O⁺ + Cl⁻ The water molecule acts as a base because it
Wittaler [7]

Answer:

accepts an H⁺

Explanation:

The following balanced ionic equation is given in this question;

HCl + H₂O → H₃O⁺ + Cl⁻

According to Brønsted–Lowry acid–base theory, a base is any substance that can accept hydrogen ions or protons (H+). Using this definition for the above equation, water (H2O) accepts a proton or H+ that was donated by HCl to form H30+ (hydronium ion), hence, water is acting as a BASE in this reaction because it accepts an H+.

How is a series circuit different from a parallel circuit?
beks73 [17]

Answer:

C. A series circuit has only one loop and a parallel circuit has two or more loops for the current to flow through

Explanation:

A circuit that are made of one loop is called series circuit. On the other hand, the parallel circuit has at least two loops. The circuit type has nothing to do with open or closed circuit.

If any part of the series circuit got cut, the current will stop flowing since there is only one loop. A parallel circuit has more loop so the circuit might still work even if a part of the circuit got cut.
