Name at least two benefits of using models in science.

Explanation:

1) it gives you a visual of what you will be doing

2) you can find more variables when looking at it compared to just thinking of it

3) gives you new insights on what is yet to come

4) allows you to answer some questions and begin testing

Models make concepts more tangible. They also make it possible to notice patterns, develop or revise representations, and predict or explain events or relationships.

Sample answer from edg

c. electrical charges of ionic bonds.

a. the law of proportion states the combination of 2 atoms in a specific ratio to produce multiple compounds such as the given statement of question ‘1st compound contains 88.8 % cu ’ indicates 88.8 g of cu is present along with 11.2 g oxygen in 100 g of compound whereas the statement ‘2st compound contains 79.9 % cu ’ indicates 79.9 g of cu is present along with 20.1 g oxygen in 100 g of compound

1st compound contains 88.8 g cu

for cu

m = 63 g /mol

atomic % = 88.8 /63 = 1.42

for o

m = 16 g /mol

atomic % = 11.2 /16 = 0.7

b. the emperical formula of 1st compound is

cu1.4o0.7
