Question

Multiple Choice Questions: 1. Non-Metals react with oxygen to produce metal oxides which are (a) Acidic in nature (b) Basic in nature (c) Neither acidic nor basic in nature (d) Both acidic and basic in nature 2. A non metal which is liquid at room temperature? (a) Gold (b) Silver (c) Copper (d) Bromine​

Answer 1

Answer:

1. Non metal oxides are basic in nature.

2. bromine is liquid at room temperature.

Answer 2

Answer:

$\boxed{\large{\bf{1. \;(a)\; Acidic \; in \; nature}}}$

$\boxed{\large{\bf{2. \;(d)\; Bromine}}}$

Explanation:

Non-Metals react with oxygen to produce non-metal oxides which are basic in nature.

• Non-metals react with oxygen to form acidic oxides.
• The acidic oxides when dissolved in water they form acids, which turns blue litmus paper red.
• (Metal oxides are formed when metals react with oxygen. They are basic in nature.)

$\rm NM + H_2O \longrightarrow Non-metallic \; Oxides$

• NM = Non Metal

2. A non metal which is liquid at room temperature?

$\longmapsto$ Bromine

• Here, in the options Gold, Sliver and Copper are metals.
• Also, all metals exist in solid state at the room temperature except mercury.
• Bromine is the last option which is a non-metal and it exist in liquid state at room temperature.
