Which statment explains the relationship between Earth's mantle and the outer core A. the outer core is more dense and farther from the surface than the mantle

B. the outer core is more dense and closer to the surface the mantle

C. the outer core is less dense and closer to the surface than the mantle

D. the outer core is less dense and farther from the surface the. the mantle​

A. the outer core is more dense and farther from the surface than the mantle

Explanation: There are two mantle‘s. But both of them are closer to the surface than the outer core. the outer core is the liquid layer outside of the inner core. The mantle is the next layer after the outer core. It goes: inner core, outer core, stiffer mantle, asthenosphere, ridged mantle, then the earth’s crust.

b. accuracy of the data matters alot more than its number of digits, organization or amount of detail. quantitative observation is more accepted than the qualitative observation.

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
