Explanation:
c is the right answer becos any substance that retains it's shape in the water is insoluble
Answer:
D
Explanation:
it's not c because energy can't disappear or be destroyed so that makes E wrong
From the balanced equation, we know that one mole of lithium oxide is produced for every two moles of lithium metal. Therefore, we have:
8 moles Lithium * (1 mole Li2O)/(2 moles Lithium) = 4 moles Li2O
Index fossils are from species that only existed for a short period of time. they are found in rocky layers, Trilobites and Graptolites are index fossils. A guide and zone fossil are used often to determine the age of the rock layer in which it is found.
According to Dalton's Law of Partial pressure, the pressure exerted by a mixture of non-reacting gases is equal to the sum of their partial pressure.
Mathematically,
Total Pressure = P₍₁₎ + P₍₂₎ + P₍₃₎ + ....... ------(1)
Data given:
Partial pressure of Nitrogen = P₍₁₎ = 587 mmHg
Partial pressure of Oxygen = P₍₂₎ = 158 mmHg
Partial pressure of Argon = P₍₃₎ = 7.00 mmHg
Putting these values in eq 1.
Total Pressure = 587 mmHg + 158 mmHg + 7 mmHg
Total Pressure = 752 mmHg
