Explanation:

The vertical rows in a periodic table are called rows. Whereas columns in a periodic table are called group.

So, elements in a periodic table when arranged in a period then they tend to repeat their properties because when the row repeats then elements with similar properties fall under same groups.

Thus, we can conclude that in the periodic table, a set of properties repeats from row to row.

The student recorded the mass of the cup + sample incorrectly and started with 2.20 g of hydrated compound but used 2.00 g in th

gtnhenbr [62]

Answer:

low

Explanation:

We were informed in the question that the student had incorrectly recorded the mass of cup + sample as 2.20 g but inadvertently used 2.00 g in the calculations.

This error will cause a slight decrease in the mass of water and ultimately decrease the number of moles of water in the hydrate.

What i am saying is that the number of moles of water obtained in the calculation will be artificially low.
