Which of the following violates the Aufbau principle?

Chemistry
1 answer:

3 0

E and B

Explanation:

The last option violates Aufbau's principle.

Aufbau's principle states that "the sublevels with lower energies are filled up before those with higher energies."

This implies that orbitals are not filled based on numerical order but on their energy levels.

The order is as follows;

   1s 2s 2p 3s 3p 4s 3d  e.t.c

In B, the 3s was not filled before jumping to 3p

In E, 3p was not filled before jumping to 3d and 3d was not even the next orbital.

the density of pure gold (au) is 19.3 g/cm3. what is the mass of a block of gold that measures 1.2 cm x 5.00 cm x 3.20 cm? pleas
Julli [10]

The density of pure gold (au) is 19.3 g/cm3. what is the mass of a block of gold that measures 1.2 cm x 5.00 cm x 3.20 cm? please show work.


Given: Density of pure gold = 19.3 g /cm^3

Measurement of block of gold =1.2 cm x 5.00 cm x 3.20 cm

To calculate : mass of gold

Formula used: Density = Mass / Volume

Volume = 1.2 cm x 5.00 cm x 3.20 cm = 19.2 cm^3

Mass of gold = Density X volume = 19.3 g /cm^3 X 19.2 cm^3  = 370.56 g

You have 4.5 x 10^24 particles of C3H8. How many grams are present?
Citrus2011 [14]

Answer:

33 g.

Explanation:

Hello there!

In this case, for these particle-mole-mass relationships problems, it is necessary for us to recall the following equivalence statement, based off the molar mass of the involved compound, C3H8, one mole of particles and the Avogadro's number:

1mol=44.11g=6.022x10^{23}molecules

In such a way, we can set up the following expression for the calculation of the mass in the given particles of propane:

4.5x10^{23}molecules*\frac{1mol}{6.022x10^{23}molecules} *\frac{44.11g}{1mol}\\\\33g

Best regards!

Calculate the energy in joules and calories required to heat 25.0 g of water from 12.5C to 25.7C
Alex Ar [27]
The heat (Q) required to raise the temp of a substance is:<span>Q=m∗Cp∗ΔT</span><span> where m is the mass of the object (25.0g in this case), Cp is the specific heat capacity of the substance (for water Cp = 1.00cal/gC, or 4.18J/gC,
and Dt is the change in temp.
You'll have to solve this twice, once with the Cp in calories, and once with the Cp in joules.
