CALCULATING HALF LIFE LAB REPORT. I need helping filling out the two tables, making a graph and answering some questions.

The tables have not been filled out yet at all, and I haven't been able to insert the graph because of it, need some help!!

Question : scientist finds a piece of wood that is thought to be from a ancient fire Circle. They find the word that contains the amount of carbon-14 see that is approximately 1/6 of the current atmospheric 14c levels determine approximately how many years ago the tree was chopped down to be used for firewood if he started with 1 million carbon-14 atoms how many atoms of remain in the wood? 14c has a t1/2 of 5, 750 years. ​

the enthalpy of formation of water is given as -285.8kj/mol, which states that the enthalpy of formation is negative.

negative enthalpy of formation indicates that the heat is released during the reaction process. the heat is released from reaction to the surroundings the enthalpy is expressed with a negative sign with the energy given out in the reaction process.

the formation of water takes place by giving out heat which is -285.8 kj/mol.

water and alcohols have similar properties because water molecules contain hydroxyl groups that can form hydrogen bonds with other water molecules and with alcohol molecules, and likewise alcohol molecules can form hydrogen bonds with other alcohol molecules as well as with water.

atomic mass = 39

number of neutrons = 20

number of protons= 19

electronic configuration = 1s2 2s2 2p6 3s2 3p6 4s1

the number of electron in first shell = 2

number of electrons in n=3 shell = 8
