Answer:

Sm (Samarium) = [Xe] 4f6 6s2

Explanation:

Noble gas electron configuration of Sm (Samarium) = [Xe] 4f⁶ 6s²

Noble gas electron configuration of Os (Osmium) = [Xe] 4f¹⁴5d⁶6s²

Noble gas electron configuration of Ba (Barium) = [Xe] 6s²

Noble gas electron configuration of Bi (Bismuth) = [Xe] 4f¹⁴5d¹⁰6s²6p³

A completely filled s, p, d, and f orbitals have 2, 6, 10 and 14 electrons respectively. Half filled s, p, d, and f orbitals have 1, 3, 5 and 7 electrons respectively.  Bi and Os have completely filled f orbitals. Sm has partially filled f orbital.

Which of the following would help you identify a titration curve that involved a strong acid titrated by a weak base?
Mariulka [41]

Answer:

The pH at the equivalence point is lower than 7

Explanation:

Given the titration involves a strong acid and a weak base

An example  is the reaction between ammonia  and hydrochloric acid  in the aqueous phase

The pH of the base will ordinarily start high and drop rapidly with the additions of acid. As the equivalence point is approached, the pH will change more gradually, until finally one drop will cause a rapid pH transition through the equivalence point.

If a chemical indicator is used—methyl orange would be a good choice in this case—it changes from its basic to its acidic colour.

In strong acid-weak base titrations, the pH at the equivalence point is not 7 but below it. This is due to the production of a conjugate acid during the titration; it will react with water to produce hydronium ions.

If 5 L of butane is reacted what volume of carbon dioxide is produced ILL GIVE BRAINLIEST
Len [333]

Answer: First, here is the balanced reaction:  2C4H10  +  13O2  ===>  8CO2  +  10H2O.

This says for every mole of butane burned 4 moles of CO2 are produced, in other words a 2:1 ratio.

Next, let's determine how many moles of butane are burned.  This is obtained by

5.50 g / 58.1 g/mole  =  0.0947 moles butane.  As CO2 is produced in a 2:1 ratio, the # moles of CO2 produced is 2 x 0.0947  =  0.1894 moles CO2.

Now we need to figure out the volume.  This depends on the temperature and pressure of the CO2 which is not given, so we will assume standard conditions:  273 K and 1 atmosphere.

We now use the ideal gas law PV = nRT, or V =nRT/P, where n is the # of moles of CO2, T the absolute temperature, R the gas constant (0.082 L-atm/mole degree), and P the pressure in atmospheres ( 1 atm).

V = 0.1894 x 0.082 x 273.0 / 1  =  4.24 Liters.
