Answer the following problems by showing your complete solutions and interpretations. Please be guided by the given criteria below. PROBLEMS 3. If a sample known to be about 28, 703 years old has 440g of C-14 atoms, how many grams of C-14 were in the sample when the organism died? 4. Scientists found a fossilized bone from an organism in a deep layer of rock. When they took the bone back to the lab, they realized that the bone had only 12.5% of the total Carbon-14 left. Based on the amount of C-14 left in the bone how old is the bone?

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.
