True or false: Wave frequency and wavelength are related. Justify your answer.
kondaur [170]

Answer:True.

As you increase the wavelength the frequency decreases.

Explanation:

The wavelength of a wave is the distance(in meters) between the two consecutive crest and trough of a wave. The S.I unit of the wavelength is meter.

The frequency of a wave is the number of complete wave cycle passing a particular point per second. The S.I unit of the frequency is Hertz.

Wave's frequency and wavelength are related to each other as

Frequency = 1 / Wavelength

As the Frequency is inversely proportional to the wavelength of a wave so as the frequency will increase the wavelength of the wave will decrease and vise-versa.

So, its true that As we increase the wavelength the frequency decreases.

We dissolve 93 grams of sodium sulfate (Na2SO4) in 20 grams of water. What is the percent by mass of sodium sulfate in this solu
dlinn [17]
It should be for the total solution of 93 plus 20 grams which is 113 grams so 93 divided by 113 grams comes to 82.3% sodium sulfate and this can be checked by multiplying 113 grams by 0.823 which results in 93 grams of sodium sulphate.

What mass of zinc will completely react with 125.0 mL of a solution of nitric acid (HNO3) which has concentration of 0.850M?
kati45 [8]

The mass of zinc required to react with HNO3 is 3.45 g

<h3>What is moles of HNO3 reacting?</h3>

The moles of HNO3 reacting is calculated using the formula below:

  • moles = concentration × volume

volume = 0.850

volume = 125.0 mL = 0.125 L

Moles of HNO3 = 0.850 × 0.125 = 0.10625 moles

Equation of reaction:

Zn + 2 HNO3 --> Zn(NO3)2 + H2

2 moles of HNO3 reacts with 1 mole of Zn.

moles of zinc reacting = 0.10625/2 = 0.053125

Mass of zinc = moles × molar mass

molar mass of Zn = 65

Mass of zinc = 0.053125 × 65

mass of Zn = 3.45 g

Therefore, the mass of zinc will completely react with 125.0 mL of a solution of nitric acid (HNO3) which has concentration of 0.850M is 3.45 g
