Marian puts a graduated cylinder marked off in
milliliters on a scale and
resets the scale to zero
so that it will not count
the mass of the cylinder.

Then Marian pours
some water into the
cylinder and records
the volume and mass
of the water.(10ML)

Next, Marian adds
some more water and
records the volume
and mass again.(17 mL)

Finally, Marian calculates
the density of water based
on her measurements.
10.13g/10mL = 1.013 g/mL
17.91g/17mL = 1.054 g/mL
Take the average of the two
measurements:
(1.013 + 1.054) ÷ 2 = 1.034.
So the density of water is
about 1.034 g/mL

Meanwhile, Jamal goes online and finds the
following information on three reliable web sites:The density of
water is 1 g/mL
(one gram per
milliliter).

Which student do you think got the most accurate answer, Marian or
Jamal?

Why are the trends and exceptions to the trends in ionization energy observed?

At 40 âc the solution has at 40 â c the solution has blank g of k n o 3 per 100 g of water and it can contain up to blank g of k n o 3 per 100 g of water. at 0 â c the solubility is ~ blank g k n o 3 per 100 g of water, so ~ blank g k n o 3 per 100 g of water will precipitate out of solution.g of kno3 per 100 g of water and it can contain up to at 40 â c the solution has blank g of k n o 3 per 100 g of water and it can contain up to blank g of k n o 3 per 100 g of water. at 0 â c the solubility is ~ blank g k n o 3 per 100 g of water, so ~ blank g k n o 3 per 100 g of water will precipitate out of solution.g of kno3 per 100 g of water. at 0 âc the solubility is ~ at 40 â c the solution has blank g of k n o 3 per 100 g of water and it can contain up to blank g of k n o 3 per 100 g of water. at 0 â c the solubility is ~ blank g k n o 3 per 100 g of water, so ~ blank g k n o 3 per 100 g of water will precipitate out of solution.kno3 per 100 g of water, so ~ at 40 â c the solution has blank g of k n o 3 per 100 g of water and it can contain up to blank g of k n o 3 per 100 g of water. at 0 â c the solubility is ~ blank g k n o 3 per 100 g of water, so ~ blank g k n o 3 per 100 g of water will precipitate out of solution.gkno3 per 100 g of water will precipitate out of solution. a kno3 solution containing 55 g of kno3 per 100.0 g of water is cooled from 40 ∘c to 0 ∘c. what will happen during cooling?

The diagrams to the right show the distribution and arrangement of gas particles in two different containers. according to kinetic-molecular theory, which of the following statements is true? check all that apply. if the temperatures of both containers are equal, container a has greater pressure than container b. if the volume of container a decreased, its pressure would decrease. if the pressure in both containers is equal, container a has a lower temperature than container b.
