True or False. Solutions for which water is the solvent are called aqueous solutions.

What element has a total of 3 p-sublevel electrons?

Crank

Elements with three p-electrons....

That would be N, P, As, Sb, and Bi -- elements in group 15

For example, energy diagram showing "empty" orbitals up through the 3p.

1s ↑↓

According to Hund's rule, the electrons singly occupy the p-orbitals, and all have the same spin.

In a lab in New York, Thomas and Nikola collected data over several trials. Thomas recorded his measurements as 10.0 A, 11 A, an

Anna11 [10]

Nikola's reading has a lower range and it is logical to conclude that his reading is more precise.

Explanation:

Precision is the ability to reproduce the same set of result from a measurement. The more repeatability a measurement is, the more precise it is.

From the given pool of data, it is easy to determine which set of data is more precise over the other.

Thomas measurements: 10.0 A, 11 A, and 8 A

Nikola measurements: 9.0 A, 9.2 A, 8.8 A

Using the range method, it is possible to find the precision in this pool of data.

Method and Solution:

Find the range of the sample:

Range = highest value - lowest value

Thomas measurement; Range = (11-8)A = 3.0A

Nikola measurement; Range = (9.2-8.8)A = 0.4A

Find the mean of the samples:

Mean of Thomas measurement = $\frac{10 + 11+ 8}{3}$ = $\frac{29}{3}$ = 9.7A

Mean of Nikola measurement = $\frac{9+ 9.2+ 8.8}{3}$ = $\frac{27}{3}$ = 9A

Now let us quote the range of value of the mean of each measurement:

Thomas 9.7±3.0A

Nikola 9.0± 0.4A

Nikola's reading has a lower range and it is logical to conclude that his reading is more precise.

If 16g of <img src="https://tex.z-dn.net/?f=CH_%7B4%7D" id="TexFormula1" title="CH_{4}" alt="CH_{4}" align="absmiddle" class="la

43.56 grams of are produced if 16g of CH4 reacts with 64g of O2.

Explanation:

Balance equation for the reaction:

CH4 + 2O2⇒ CO2 +2H2O

Data given : mass of CH4 =16 grams atomic mass = 16.04 grams/mole

mass of water 36 gram atomic mass = 18 grams/moles

mass of CO2=? atomic mass = 44.01 grams/mole

number of moles = $\frac{mass}{atomic mass of one mole}$ equation 1

number of moles in CH4

n = $\frac{16}{16.04}$

= 0.99 moles

Since combustion is done in presence of oxygen hence it is an excess reagent and methane is limiting reagent so production of CO2 depends on it.

From the equation

1 mole of CH4 gave 1 mole of CO2

O.99 moles of CH4 will give x moles of CO2

$\frac{1}{1}$ = $\frac{x}{0.99}$

x = 0.99 moles of carbon dioxide

grams of CO2 = number of moles x atomic mass

= 0.99 x 44.01

= 43.56 grams of CO2 is produced.
