Correct to 3 decimal places: 47,822.643 g/cm^3
The bonds that hold atoms together to form molecules are called covalent bonds. They are pretty tough and not easily made or broken apart. It takes energy to make the bonds and energy is released when the bonds are broken. Trees take light and use it to make bonds between carbon atoms and molecules of cellulose. I hope this helps:)
Answer:
nuclear decay I believe not 100% sure though.
Explanation:
It is advisable to wear long sleeve when when a student is working in a chemistry lab so that to protect arms from lab chemicals. when someone enter the chemistry lab to wort or to study should be well prepared with appropriate gears and security measure to avoid injury.
A. An element in its pure state is always 0.
B. One of the oxidation rules is that H with a nonmetal (which is Cl) is always +1. Cl would be -2 because -2 + (+1) equals -1.
C. Oxygen is always -2, so Cl- would have to be -1 to equal -3.
It has been awhile since I learnt this in AP Chem so answers could be a little rusty. Hopefully it helps.
