Answer:
A warm shallow sea.
Explanation:
A warm, shallow sea invaded the Big Bend during the Cretaceous Period, some 135 million years ago, providing the setting for deposition of lime mud and the remains of sea-dwelling organisms such as clams and snails. Limestone layers formed from those shallow muds are now visible throughout much of the Big Bend.
I believe the bond between between F and Cl would be polar covalent.
Answer:
78.9% yield
Explanation:
% Yield = Actual Lab Yield/Theoretical Yield x 100%
= (204.6g)/(256.5g)·100% = 79.8% Yield
What are the elements so i can help?????
Answer:
the efficiency of the Carnot engine is e=0 .5060 (50.96%)
Explanation:
The carnot cycle effifiency e is calculated through
e = W/Q₂
where
W= work
Q₂= heat absorbed
Q₁= heat exhausted
from an energy balance
W= Q₂ - Q₁ ( the proportion of the heat absorbed that was not released was converted to work)
therefore
e=(Q₂-Q₁)/Q₂ = 1 - Q₁/Q₂ = 1 - 51 J/104 J = 0.5060 (50.96%)
