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.
A piece of copper has a volume of 560 L what is mass of sample in grams. For the problem it gives me
1cm^3Cu = 9g CU 9.5 x 10^21 atoms Cu= 1 Cu
1KG =1000g 1cm^3 =1mL
1L=1000cm^3
It basically wants me to write out the conversions correctly i just dont know which ones to use. Thank you so much for the help I really appreciate it.
