Which one of the following statements is FALSE? a In a neutralization reaction, an acid reacts with base to produce a salt and H

2O. b Spectator ions" appear in the total ionic equation for a reaction, but not in the net ionic equation c HF, HCl, and HNO3 are all examples of strong acids. d Titration is a process which can be used to determine the concentration of a solution. e For the reaction of a strong acid with a strong soluble base, the net ionic equation is always H+ + OH- --> H2O

Answer: Option (c) is the correct answer.

Explanation:

HF is a weak acid and not a strong acid. This is because fluorine is a highly electronegative atom and when it combines with a hydrogen atom then it will attract the valence electron of hydrogen atom more towards itself.

As a result, it will not dissociates easily to give hydrogen ion. Hence, it acts as a weak acid.

A neutralization reaction is defined as a reaction in which an acid reacts with a base to give salt and water. For example, HCl + NaOH \rightarrow NaCl + H_{2}O

It is true that, spectator ions "appear in the total ionic equation for a reaction, but not in the net ionic equation".

Titration is defined as a process in which concentration of an unknown solution is determined using a solution of known concentration.

Thus, we can conclude that the statement HF, HCl, and HNO3 are all examples of strong acids, is false.

Answer:

The answers are options A, D and E

Explanation:

Shut circuit implies a total electrical association around which flow streams or courses. When you have a progression of electrical wires interfacing with one another and finishing a circuit so flow goes from one end of the hover to alternate, this is a case of a shut circuit. A broken wire or an "open" (off) switch both leave holes in a circuit keeping electrons from going from one side of the power source to the next. In this way, electrons won't stream. This circumstance is called an open circuit. A shut (on) switch implies that the circuit through the switch is connected.The meaning of an open circuit is a broken way for an electrical flow because of an open switch or frayed wire. A case of an open circuit is a string of electric lights that don't work on the off chance that one globule goes out. YourDictionary definition and utilization precedent. Shut circuit implies an entire electrical association around which flow streams or circles. When you have a progression of electrical wires associating with one another and finishing a circuit so flow goes from one end of the hover to alternate, this is a case of a shut circuit.
