The atoms on the outermost level are called electrons.
Answer:
if I knew the was a reaction taking place I would say it's lost in the atmosphere as gas
Answer:
The false statement from the given statements is option a.
Explanation:
Hypothesis:
A hypothesis is a intelligent guess or prediction to interpret or explain any phenomena.
It is tested through the series of experiments and by number of studies to actually decide whether hypothesis is in agreement with observation and results predicted by it. These prediction are made on basis of limited evidences. It can be false or true.
Theory:
A theory is an in depth explanation behind any physical phenomena which has been tested multiple times through the correct scientific methods and experimentation. It will give same results and observations.
Battery or electrochemical cell
Explanation:
A battery is a power source that directs electrons from oxidation - reduction reactions to flow through a device to give electrical power.
- A battery is an electrochemical cell.
- Electrochemical cells are devices in which chemical reactions produce an electric current that is, chemical energy is turned into electrical energy.
- The reactions here are spontaneous redox reactions, hence electrons flows on its own in an external circuit.

To calculate percent composition, you first need to find the molar mass of C (carbon), H (hydrogen) and O (oxygen).
C is 12.01
H is 1.00
O is 16
Then multiply each by the number of atoms of each element in the formula (the number that comes after each element in the equation for example C6 means 6 carbon atoms.
C: 12.01 x 6= 72.06
H: 1x12= 12
O: 16x6= 96
Then add them up.
72.06+ 12+ 96= 180.06
Now find the percent composition of carbon.
72.06/ 180.06 x 100= 40.01%
So the answer is C 40%.
