The answer is 1.14 atm.
Use the Combined Gas Law on the reference tables to answer this question. You can ignore the temperature portion because it remains constant in this particular case.
25x = (15)(1.90)
25x = 28.5
x = 1.14 atm
Sorry If it’s wrong but it should be c d
From the relationship between wavelength and frequency, the frequency of the wave is reduced by half to 60 Hz as the wavelength is increased twice to 10 m at constant speed.
<h3>What is the relationship between wavelength, velocity and frequency of a wave?</h3>
The velocity, frequency and wavelength of a wave are related by the formula given below:
where
- v is velocity
- f is frequency
- λ is wavelength of the wave
From the above relationship:
If the wavelength of a wave is increased to 10m but the speed stays the same at 600 m/s, the frequency can be calculated as follows:
f = v/λ
f = 600/10
f = 60 Hz
Therefore, the frequency of the wave is reduced by half as the wavelength is increased twice at constant speed.

The answer is (4) zinc. Zinc can react with HCl at room temperature spontaneously and create H2. You can know this property from the metal activity order.
