I believe the statement given above is true. When solid mercury (ii) nitrate is being heated, a decomposition reaction happens. The solid would decompose into 3 different substances - solid mercury (ii) oxide, gaseous nitrogen dioxide, and oxygen. The balanced chemical reaction would be written as:
2Hg(NO3)2 = 2HgO + 4NO2 +O2
<span>Decomposition reaction is a type of reaction
where it involves a single compound breaking down into two or more products.
These reactions often requires an energy source thus it is an endothermic
reaction. This is evident for this reaction since we supplied heat to the reactant for the reaction to proceed.</span>
Answer:
6 mol H, 9 mol O2
Explanation:
We can see that in water, there are 6 moles of hydrogen, and for oxygen, there is 9 moles
Explanation:
The highest number is the strongest base. Therefore the pH of 12 is the strongest base here (C).
The theoretical yield of a reaction is 28% if 25.0 grams of product were actually produced from a reaction that has a 88% yield .
The theoretical yield of a reaction is calculated in following steps .
Identify the limiting reagent, which is the reagent with the fewest moles.
Divide the fewest number of reagent moles by the stoichiometry of the product.
Multiply the result of Step 3 by the molecular weight of the desired product.
theoretical yield : the maximum amount of product that can be produced from a given amount of reactant. this quantity of product is rarely produced during a chemical reaction. limiting reactant.
