Explanation:
(a) Chlorine the first row Is 1s the second is 2s followed by 2p...etc as Chlorine has 17 electrons
D)they were formed veritcally
The answer would be water , carbon dioxide and methane because they all contain more than one element.
Water-H2O
Carbon Dioxide-CO2
Methane-CH4
Low potential energy means there are fewer chemical bonds so H2O has Less than C6H12O6 because their are less valence electrons making bonds with others. in an endothermic reaction heat goes into the product so the reactants would have less potential energy.
Answer:
Repetition
Explanation:
The best term to describe this example is repetition and not replication.
Most times, to obtain an accurate and precise reading which is reliable, scientist makes several repeated measurements. The average gives the most reliable representation of the phenomenon being tested.
This process is called repetition.
On the other hand, duplicating an experiment is replication. Experiments are replicated to proof their validity.
- Since this is a brand new experiment where 16 height measurements are reported, we are dealing with a repetition situation.
