Chemistry
1 answer:
SVEN [57.7K]3 years ago
3 0

Answer:

λ = 0.38 ×10⁻⁹ m

Explanation:

Given data:

Wavelength of xray = ?

Frequency of xray = 7.8 ×10¹⁷ Hz

Solution:

Formula:

Speed of light = wavelength × frequency

speed of light = 3×10⁸ m/s

Now we will put the values in formula.

3×10⁸ m/s = λ × 7.8 ×10¹⁷ Hz

λ = 3×10⁸ m/s / 7.8 ×10¹⁷ Hz

         Hz = s⁻¹

λ = 3×10⁸ m/s / 7.8 ×10¹⁷s⁻¹

λ = 0.38 ×10⁻⁹ m

If a gas at 25.0 °C occupies 3.60 liters at a pressure of 1.00 atm, what will be its volume at a pressure of 2.50 atm?
Llana [10]
Since the temperature is constant, therefore, this problem can be solved based on Boyle's law.
Boyle's law states that: " At constant temperature, the pressure of a certain mass of gas is inversely proportional to its pressure".

This can be written as:
P1V1 = P2V2
where:
P1 is the initial pressure = 1 atm
V1 is the initial volume = 3.6 liters
P2 is the final pressure = 2.5 atm
V2 is the final volume that we need to calculate

Substitute with the givens in the above mentioned equation to get the final volume as follows:
P2V1 = P2V2
1(3.6) = 2.5V2
3.6 = 2.5V2
V2 = 3.6 / 2.5 = 1.44 liters

Ferrous sulfate (FeSO4) was used in the
BARSIC [14]

Ferrous sulfate (FeSO4) is obtained by the reaction of aqueous ferric sulfate with gaseous sulfur dioxide and water according to the equation below:

Aqueous ferric sulfate = Fe_2(SO_4)_3_{(aq)}

Gaseous sulfur dioxide = SO_2_{(g)}

Water = H_2O_{(l)}

Aqueous sulfuric acid =  H_2SO_4_{ (aq)}

Aqueous ferrous sulfate =  FeSO_4_{ (aq)}

Thus, the balance equation becomes:

Fe_2(SO_4)_3_{(aq)} +  SO_2_{(g)} + 2H_2O_{(l)} ---> 2 H_2SO_4_{ (aq)} + 2 FeSO_4_{ (aq)}
