In your own words,provide 2 advantages of using meters as a measurement of length rather than old measurements of length such as

hands and steps

Dafna1 [17]3 years ago
7 0

Answer:

1.Accuracy

2.Acceptance

Explanation:

1. The first advantage is Accuracy. Using meters gives us a far more precise unit of measurement because of the exact scale of reading whereas hands and steps are more of approximate methods as they may not be as accurate as the using meter due to lack of exact scale of reading.

2. The second advantage is Acceptance. Usage of meter as a unit of measurement of length is now a widely accepted unit of measurement whereas, hands and steps are not widely accepted due to their approximate nature as compared to the exact nature of metres.

Mole fraction of Oxygen=0.381

Mole fraction of Oxygen= (range of moles of oxygen) ÷(general moles)

also, mole fraction of oxygen = (partial stress of oxygen) ÷ (total strain)

consequently , mole fraction of Oxygen= (2.31 atm)÷(2.31 atm + 3.75 atm)

= 0.381

The mole fraction may be calculated by means of dividing the variety of moles of 1 element of a solution by the entire quantity of moles of all the additives of a solution. It is cited that the sum of the mole fraction of all of the components inside the solution should be identical to 1.

Mole fraction is a unit of awareness. in the solution, the relative amount of solute and solvents are measured by way of the mole fraction and it's far represented through “X.” The mole fraction is the variety of moles of a selected aspect inside the answer divided by way of the entire range of moles in the given answer.

Mole fraction is the ratio between the moles of a constituent and the sum of moles of all ingredients in a mixture. Mass fraction is the ratio between the mass of a constituent and the full mass of a mixture.

Assuming that only the listed gases are present, what would the mole fraction of oxygen gas be for each of the following situations? A gas sample of 2.31 atm of oxygen gas and 3.75 atm of hydrogen gas react to form water vapor. Assume the volume of the container and the temperature inside the container does not change.

Serga [27]

Answer:

( a ) Filtration

( b ) sugar refining .

Explanation:

( a ) Filtration

By the process of filtration pasta from water can be removed , as pasta is not soluble in water , hence , by filtration , the solid pasta will remain in the filtration funnel , and the water will flow down , thereby , removing pasta from the water .

( b ) sugar refining

The raw sugar can be purified from the process of sugar refining .
