Answer:
fe+s is a mixture of iron and sulphur and it can be separated by magnetic separation. But FeS is a compound formed by heating iron and sulphur together.it can't be separated by any method.
Here are some of the differences between a mixture of iron and sulfur, and iron sulfide: the mixture can contain more or less iron, but iron sulfide always contains equal amounts of iron and sulfur. the iron and sulfur atoms are not joined together in the mixture, but they are joined together in iron sulfide.
Answer:
The fractional saturation for hemoglobin is 0.86
Explanation:
The fractional saturation for hemoglobin can be calculated using the formula
Where 
is the fractional oxygen saturation
is the partial pressure of oxygen
is the partial pressure when 50% hemoglobin is saturated with oxygen
and h is the Hill coefficient
From the question,
= 40 mm Hg
= 22 mm Hg
h = 3
Putting these values into the equation, we get
Hence, the fractional saturation for hemoglobin is 0.86.
Answer:
Independent variable: Colour of the container
Dependent variables: The water amount and the room temperature
3 Constants: Amount of water, location of the containers and the container size.
Hypothesis: I think that the black container will heat up the water the fastest, as the colour black absorbs heat.
Hope it helps! :)
