A 8.0 L sample at 25•C and 1.00 atm of pressure contains 0.5 moles of gas. If an additional 0.75 moles of gas at the same pressu

re and temperature are added,what is the final total volume of the gas?

Answer: The final total volume of the gas is 20 L

Explanation:

According to the Avogadro's law, the volume of gas is directly proportional to the number of moles of gas at same pressure and temperature. That means

V\propto n

or,

\frac{V_1}{V_2}=\frac{n_1}{n_2}

where,

V_1 = initial volume of gas = 8.0 L

V_2 = final volume of gas = ?

n_1 = initial moles of gas = 0.5 moles

n_2 = final moles of gas = 0.5 + 0.75 = 1.25 moles

Putting in the values , we get:

\frac{8.0}{V_2}=\frac{0.5}{1.25}

V_2=20L

The final total volume of the gas is 20 L

Good electrical conductivity and electronegativities less than 1.7 are the properties and characteristic of Group 2 elements at STP.

<h3>What are the properties of group 2 elements?</h3>

Group 2 elements are metals so they are good conductors of heat and electricity. It has electronegativity values less than 1.7 and very reactive. They form 2+ charge in cationic form and also formed ionic bonds with other negatively charged elements.

So we can conclude that good electrical conductivity and electronegativities less than 1.7 are the properties and characteristic of Group 2 elements at STP.

A microwave can have a frequency of 3.8 X 1010Hz. How much energy does this microwave give off in joules?
Marina86 [1]

Answer:

2.52 x 10^{-23} J

Explanation:

The energy given off by the microwave can be determined by the application of Planck's energy formula:

E = hf

where: E is the required energy, h is Planck's constant (6.626 x 10^{-34}m^{2}Kg/s), and f is the frequency (3.8 x 10^{10} Hz).

So that;

E = 6.626 x 10^{-34} x 3.8 x 10^{10}

  = 2.51788 x 10^{-23}

Therefore, the energy released by the wave is 2.52 x 10^{-23} J.

If a light bulb is missing or Broken in a parallel circuit,will the other bulb light
umka2103 [35]
Yes, if it’s a parallel circuit the wires are two different wires so it will light because that bulb isn’t connected to the one that went out
