Imagine that you perform a combination reaction between 30.0 g of sodium metal (Na) with 20.0 g of nitrogen gas (N2). Answer each of the following questions and show all your work. Clearly indicate parts (a), (b), etc. in your answers. (a) Write the balanced chemical equation for this reaction with the correct product. Use the "subscript button" in the toolbar above the answer box to put the chemical formulas in the proper format (it looks like this: ). Phase designations (s, l , g) are optional. (b) How many moles of sodium is 30.0 g? (c) How many moles of nitrogen gas is 20.0 g? (d) What is the limiting reactant? (e) How many grams of the product can be made?
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.
