Two basic properties of the gas phase are
Molodets [167]
The choices can be found elsewhere and as follows:

A.) a definite shape and a definite volume
B.) a definite shape but no definite volume
C.) no definite shape and no definite volume

I believe the correct answer is option C. Two basic properties of the gas phase would be it has no definite shape and no definite volume. It takes the shape and volume of its container. Hope this answers the question.

Calculate the volume in liters of a barium acetate solution that contains of barium acetate . Be sure your answer has the correc
Ilya [14]

Answer:

1.09 L

Explanation:

There is some info missing. I think this is the original question.

<em>Calculate the volume in liters of a 0.360 mol/L barium acetate solution that contains 100 g of barium acetate. Be sure your answer has the correct number of significant digits.</em>

<em />

The molar mass of barium acetate is 255.43 g/mol. The moles corresponding to 100 grams are:

100 g × (1 mol/255.43 g) = 0.391 mol

0.391 moles of barium acetate are contained in an unknown volume of a 0.360 mol/L barium acetate solution. The volume is:

0.391 mol × (1 L/0.360 mol) = 1.09 L

A spectral line has a wavelength of 7.35 *10-7 m. What is the energy of this radiation?
antoniya [11.8K]

Answer:

2.7 x 10^-19 J

Explanation:

The formula needed for this problem is

E = hν

where E = energy, h = Planck's constant = 6.626x10^-34 and ν is the frequency

c = λν

where c = speed of light = 3x10^8, and λ = wavelength

3x10^8 = 7.35x10^-7 . ν

ν = 4.08 x 10^14 Hz

E = 6.626x10^-34 . 4.08x10^14 = 2.7 x 10^-19 J
