Which of the following conclusions might a scientist make when fossils of two different species of very similar organisms are found in different layers of rock?
Question 2 options:
A. Both organisms had similar behaviors.
B. One organism was prey for the other organism.
C. One organism was ancestor of the other organism.
D. Both organisms lived around the same time.
Answer:
if its multiple, C and D, if not, C
Explanation:
brainliesttt?
One organism was ancestor of the other organism and both organisms lived around the same time is the conclusion made by scientist.
Who are fossil scientist?Fossil scientist are the specialists in studying the ancient fossils of animals and plants.
If fossils of two different species of very similar organisms are found in different layers of rock then it might be the possibility that one organism was ancestor of the other or both organisms lived around the same time. Because it is not necessary that if two species had the same organism then they have same behavior.
Hence, option (c) & (d) is correct.

If 9.87g of As2O3 reacts with carbon, then 7.71g of As should be produced. If only 6.33g of As is actually produced, what is the percent yield of As?
a 82.1%
b 0.821%
c 64.1%
d 0.641 %
Answer:
A
Explanation:
Percent yield= Actual yield/Theoretical yield x 100
The problem tells you that 6.33g of As is produced (actual yield), but 7.71g should be produced (theoretical yield). So 6.33/7.71= 0.821 x 100= 82.1%
Answer:

Explanation:
48g of methane was burned in an excess of air. What mass of carbon dioxide would be produced in the reaction assuming complete combustion? Use the information below to answer the question.
Answer:
132g
Explanation:
CH4= 12+4=16
moles= m/Mr moles=48/16=3 mol
CO2= Mr=44
there are the same number of moles as methane:
Mass= Mrxmoles
44x3=132g
The mass of the carbon dioxide produced by the combustion of the 48 g of methane is equal to 132 g.
What is the combustion reaction?Combustion reaction involves the complete oxidation of the hydrocarbon such reactions generally release only carbon dioxide and water as products.
A hydrocarbon undergoes combustion to produce carbon dioxide and water as the product. No other side products are formed in the combustion reaction.
The given combustion reaction of the methane can be written as follows:
CH₄ + 2 O₂ → CO₂ + 2H₂O
Given the amount of methane for combustion = 48 g
The molar mass of methane = 16g/mol
The molar mass of the carbon dioxide, CO₂ = 44g/mol
16 grams of methane produce carbon dioxide = 44g
The 48 grams of methane will produce CO₂ = (44/16) ×48 = 132 g
Therefore, the mass of 132 g of carbon dioxide is produced by the combustion of 48g of methane.
