How many atoms are in lead (III) bicarbonate?

1 answer:

6 0

Answer:Lead is a relatively unreactive post-transition metal. Its weak metallic character is illustrated by its amphoteric nature; lead and lead oxides react with acids and bases, and it tends to form covalent bonds. Compounds of lead are usually found in the +2 oxidation state rather than the +4 state common with lighter members of the carbon group. Exceptions are mostly limited to organolead compounds. Like the lighter members of the group, lead tends to bond with itself; it can form chains and polyhedral structures.

Which pair of substances would most likely result in the production of a gas when reacting with an acid?

vovangra [49]

Answer: metal and carbonate

Explanation:

According to Arrhenius concept, a base is defined as a substance which donates hydroxide ions $(OH^-)$ when dissolved in water and an acid is defined as a substance which donates hydrogen ions $(H^+)$ in water.

An acid is represented as :

$HX\rightarrow H^++X^-$

1. When metal is treated with an acid such as $HCl$ , if the metal is more reactive than hydrogen displaces hydrogen from its salt solution and thus produce zinc chloride and hydrogen gas.

$M+xHCl(aq)\rightarrow MCl_x(aq)+xH_2(g)$

2. When carbonates are treated with acid, double displacement takes place ad carbon dioxide is released as a gas.

$MCO_3(aq)+xHCl(aq)\rightarrow MCl_x(aq)+xH_2O(l)+CO_2(g)$
