What error, if any, would the calculated density of the solid have if the material had a hollow center?

Chemistry
1 answer:
maria [59]3 years ago
3 0

Answer:

3) The calculated density would be high, because the volume would be incorrectly measured low.

Explanation:

Density is defined as mass per unit volume. It means the density is inversely proportional to the volume.

A solid with a hollow center will have high volume due to air inside the hollow area that will lead to low density.

But the error in the calculation of density is that the "density would be high, because the volume would be incorrectly measured low."

Hence, the correct answer is "3)"

The total pressure of gases a, b, and c in a closed container is 4.1 atm. if the mixture is 36% a, 42% b, and 22% c by volume, w
Natali [406]

 The  partial  pressure of  gas C  is 0.902  atm


  calculation

partial pressure of gas c  =[( percent by volume of  gas   C /  total  percent)   x total pressure]


percent  by  volume of gas C= 22%

Total   percent  = 36% +42%  + 22%  = 100 %

Total  pressure  =  4.1 atm


partial  pressure  of gas C  is therefore =  22/100 x 4.1 atm = 0.902  atm

An element with the valence electron configuration 4s24p4 would form a monatomic ion with a charge of fill in the blank 5 . In o
nordsb [41]

Answer:

Charge= -2.

Gains two electron into the 4p^4 to become 4p^6.

Explanation:

The element in the periodic table/chart that matches with the valence electron configuration is Selenium with full electron configuration of [Ar] 3d^10 4s^2 4P^4 which is a non-metal that is found in group 4 of the periodic table/chart.

Selenium can receive 2 more electrons on the 4p^4 to give a -2(minus 2) ion that is Se^2-.

Selenium can also loose 2 electron from 4s^2 to give a +2 ion that is Se^2+.

Selenium can also loose 2 electrons from 4s^2 and 2 electrons from 4p^4 to form Se^4+.

Selenium can also loose 2 electrons from 4s^2 and 4 electrons from 4p^4 to form Se^6+.

Thus, in order to form a monatomic ion with a charge(we will be making use of the most stable one). Thus, it will gain two more electron since this is easier to become 4s^2 4p^6.
