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.

Which of the following processes is a physical change? (a) evaporation of water; (b) combination ofhydrogen and oxygen gas to produce water; (c) dissolution of sugar in water; (d) separation of sodium chloride (table salt) into its constituentelements, sodium and chlorine; (e) combustion of sugar to produce carbon dioxide and water.
A student finds that 24.96 g of water at 24.9 C(density=0.9971 g/cm3) is required to completly fill an empty flask. The water is removed and completely dried; granular solid copper weighing 51.24g is then added to the flask. With the copper present in the flask, it was determined that 19.24 g of water was required to fill the remaining space in the flask completly 1.) volume of the empty flask 2.) volume of the copper 3.) density of the copper
(1) A rectangular block of wood has the following dimensions: 10.0 cm x 5.00 cm x 4.00 cm. The block weight 100 g. What is the density of the block of wood? (2) What is the mass of a 400-mL sample of ethyl alcohol if its density is 0.8 g/mL?
Suppose the densities of two metals are so close together that density is difficult to use to be able to distinguish them within the margin of error (a good example would be zinc and tin). What other physical properties could you use to determine which metal was which? Explain your reasoning thoroughly.
