[D]. Ag2S and Ag3N



Q7

Gaurav appeared in class test where he wrote some statements but he confused to know the correct statement. Would you help him to know that?

[A]. Non-metals form negatively charged ions by gaining electrons when reacting with metals.
[B]. Non-metals form oxides which are either acidic or neutral.
[C]. Non-metals do not displace hydrogen from dilute acids. They react with hydrogen to form hydrides.
[D]. All the above
Q8

Generally, metals react with acids to give salt and hydrogen gas. Which of the following acids does not give hydrogen gas on reacting with metals (except Mn and Mg)?

[A]. H2SO4
[B]. HCl
[C]. HNO3
[D]. All of these




Q9

Consider the following statements, choose the incorrect one:

[A]. Gold being least reactive metal has been placed at the bottom in the series.
[B]. If a metal is below hydrogen in the activity series, then it will easily react with water and acids to produce hydrogen gas.
[C]. Potassium is the most reactive metal here, so it has been placed at the top in the reactivity series.
[D]. All the metals placed below hydrogen in the reactivity series lose electrons less readily than hydrogen.
Q10

The ability of metals to be drawn into thin wire is known as:

[A]. Ductility
[B]. Malleability
[C]. Sonorousity
[D]. Conductivity



Hydrogen gas is not evolved when a metal reacts with nitric acid. Why?

It is because HNO3 is a strong oxidising agent. It oxidises the H2 produced to water and itself gets reduced to any of the nitrogen oxides (N2O, NO, NO2). But magnesium (Mg) and manganese (Mn) react with very dilute HNO3 to evolve H2 gas.

Why does Magnesium float on the surface of hot water?

Magnesium reacts with hot water to form magnesium hydroxide and hydrogen. It starts floating due to the bubbles of hydrogen gas sticking to its surface.

Why do ionic compounds have high melting and boiling points?

This is because a considerable amount of energy is required to break the strong inter-ionic attraction.

Why are the sulphides and carbonates converted into their oxides during the extraction of metal?

It is easier to obtain a metal from its oxide, as compared to its sulphides and carbonates. Therefore, prior to reduction, the metal sulphides and carbonates must be converted into metal oxides.

All the Multiple Choice questions are prepared by the subject expert. Only important questions for board examinations are included here with answer and explanation. There are four choices with one correct choice. About 25 sets of MCQ online tests are given to use free.
