Answer: The precipitate formed is 
Explanation:
A double displacement reaction is one in which exchange of ions take place. The salts which are soluble in water are designated by symbol (aq) and those which are insoluble in water and remain in solid or precipitated form are represented by (s) after their chemical formulas.
A double displacement reaction in which one of the product is formed as a solid is called as precipitation reaction.
The balanced chemical equation is:
Answer:
answering this for points! Sorry! but its probably A OR C
Explanation:
Answer:Increasing the concentration of reactants generally increases the rate of reaction because more of the reacting molecules or ions are present to form the reaction products. This is especially true when concentrations are low and few molecules or ions are reacting.
Explanation:
True it is based on a set of observations
The 3 common gases that give off reactions are Hydrogen sulfide, Carbon monoxide, Nitrogen oxides.
<h3>What are off reactions</h3>
Off reactions are defined as chemical reactions that occurs when something burns or during combustion of materials which gives off energy.
Some gases that give off reaction are:
- Hydrogen sulfide
- Carbon monoxide
- Nitrogen oxides
Note that these gases are mostly poisonous.
Therefore, the 3 common gases that give off reactions are Hydrogen sulfide, Carbon monoxide, Nitrogen oxides.
