Answer:

5.168 L

Explanation:

Applying Charles Law,

V/T = V'/T'..................... Equation 1

Where V = Initial Volume, T = Initial Temperature in Kelvin, V' = Final Volume, T' = Final Temperature in Kelvin,

Make V' the subject of the equation,

V' = VT'/T................. Equation 2

From the question,

Given: V = 5L, T = 25°C = (25+273) = 298K, T' = 35°C = (35+273) = 308K

Substitute these values into equation 2

V' = (5×308)/298

V' = 5.168 L

Explain why the 4s sublevel fills before the 3d begins to fill as electrons are added.
tamaranim1 [39]

Answer: The energy of the 4-s subshell is lower than the energy of 3-d subshell.

Explanation:

During the filling of electrons in subshells, the lower energy levels are filled before the higher energy levels. Also known as Aufbau principle.

Energy of the sublevel = (n + l)

where : n = Principal quantum number

             l = Azimuthal quantum number(s=0,p=1,d=2,f=3)

Energy of 4-s subshell= (4+0) = 4

Energy of 3-d subshell=(3+2) = 5

Energy of 4-s subshell is lower than the energy of 3-d subshell, that is why 4s orbital is filled before the 3-d subshell.

Dolomite, [CaMg(CO3)2] is found in a soil sample. A geochemist titrates 24.65 g of soil with 57.85 mL of 0.3315M HCl. What is th
pshichka [43]

In order to find out the %mass dolomite in the soil, calculate for the mass of dolomite using the information given from the titration procedure. You would need to multiply 57.85 ml with 0.3315 M HCl and you would get the amount of HCl in millimoles. Then multiply the amount of HCl with 1/2 (given that for every 1 mol of dolomite, 2 mol of HCl would be needed). Convert the amount of dolomite to mass by multiplying the millimoles with the molecular weight which is 184.399. Then convert the mass to grams which is 1.768 grams. Divide the mass of dolomite (1.768 grams) with the weight of soil sample. The % mass is 7.17.
