Answer:
30.26 grams of N₂O₃
Explanation:
Divide by Avogadro's number. This leaves you with the number of moles. Then, multiply by the molar mass of N₂O₃
3 cubic centimeters, Volume= density/ mass
First we have to establish the chemical reaction. As a result of adding N<span>a2CO3 and AgNO3 products formed are NaNO3 and Ag2CO3. NaNO3 is a soluble substance when dissolved in water.
As a general rule, most Ag, Pb and Hg(I) compounds are considered insoluble. Ag2CO3 is insoluble in water hence the reaction given forms a precipitate. </span>
The most important thing to determine whether a change is physical or chemical is whether the substance was changed. When the substance being changed, it is chemical change. Otherwise, it is physical.
Answer:
It determines the maximum amount of the product that can be formed
Explanation:
Usually when performing a chemical reaction, it is hard to measure the exact amounts of the two reactants to react completely. This is why generally we take one reactant as our limiting reagent and another reagent in excess.
The reactant that is limiting reacts completely, while the reactant in excess still remains in a solution after reaction is over.
The importance of the limiting reactant is huge: it determines the maximum amount of the product that can be formed. It's limiting and, therefore, the extent of the reaction depends on how much of the limiting reagent we have. According to stoichiometry, we find the moles of a product formed directly from the limiting reagent, while the reagent in excess doesn't provide any relevant information.
