If so, what is the molecular formula of the precipitate and which are spectator ions? c. If 10.0 g of sodium carbonate and 10.0 g of calcium nitrate are combined, What is the limiting reactant?
States of Matter
The substance that constitutes everything in the universe is known as matter. Matter comprises atoms which in turn are composed of electrons, protons, and neutrons. Different atoms combine together to give rise to molecules that act as a foundation for all kinds of substances. There are five states of matter based on their energies of attraction, namely solid, liquid, gases, plasma, and BEC (Bose-Einstein condensates).
Chemical Reactions and Equations
When a chemical species is transformed into another chemical species it is said to have undergone a chemical reaction. It consists of breaking existing bonds and forming new bonds by changing the position of electrons. These reactions are best explained using a chemical equation.
1. Sodium carbonate is combined with calcium nitrate.
a. Write the molecular, ionic equation, and net ionic equation for the reaction that occurs.
b. Is there a precipitate? If so, what is the molecular formula of the precipitate and which are spectator ions?
c. If 10.0 g of sodium carbonate and 10.0 g of calcium nitrate are combined, What is the limiting reactant?
d. What is the maximum amount, in grams, of calcium carbonate that can be produced?
e. How much excess reactant is left if all the limiting reactant is converted to products?
f. If 1.0 g of calcium carbonate was collected from the reaction in part (b), what is the percent yield of the reaction?
