Chemistry
1 answer:
Westkost [7]4 years ago

Answer:

Option D (NaNO_3)

Explanation:

Acids react with metal to form salt and hydrogen gas.

Metals which are more reactive than hydrogen evolve hydrogen gas on reaction with acid.

For example:

Magnesium reacts with hydrogen chloride to form magnesium chloride and hydrogen.

2HCl(aq) + Mg(s) → MgCl2(aq) + H2(g)

Al and Zn are more reactive than hydrogen, therefore, these metals evolve hydrogen gas on reaction with acid.

NaNO_3 reacts with HCl to form NaCl and nitric oxide.

HCl+NaNO_3 \rightarrow NaCl+HNO_3

K_2CO_3 reacts with HCl to form potassium chloride, carbon dioxide and water.

HCl+K_2CO_3 \rightarrow KCl+CO_2+H_2O

As reaction of  NaNO_3 does not evolve any gas, therefore, the correct option is D.

In a given column of the periodic table the elements have _____.
kakasveta [241]

Answer:

a. similar properties

Explanation:

In a given column of the periodic table, the elements have similar properties.

A column on the periodic table is known as a group or family. The group is a vertical arrangement of elements  on the periodic table.

Elements in the same group have the same number of valence electrons after their group number.

For example, all the elements in group 1 have one valence electron. Those in group 2 have 2 valence electrons.

The valence electrons of an atom determines its chemical properties. So, all elements in the same group have the same chemical properties.
