Elements that belong to the same period which is seen horizontally in the periodic table have different properties. Elements with similar properties are seen in columns or groups. Elements in the same period have similar principal quantum number and belong to the same principal shell. Hence the answer is that t<span>hey have different properties that repeat across the next period</span>.
1 atm = 101,325 Pa = 101.325 kPa
Pa is Pascals, and kPa is kilopascals.
0.750 atm * 101.325 kPa/1 atm = 75.99 kPa = 76.0 kPa
The answer needs to be in 3 significant figures, and therefore 0.750 atm = 76.0 kPa.
When I think of science, I think of factual evidence from the use of experimentation.
Science is hypothesizing research in order to confirm if the experimentations are true or not.
