Iii. A sound wave can be modelled by using a slinky spring. A wavelength in this model is...
OLga [1]

Answer: d. the distance between two rarefactions,

Explanation:

Wavelength is the distance between two identical adjacent points in a wave. This means that it is the distance between two adjacent compressions or two adjacent rarefactions.

Wavelengths are inversely related to frequency because the longer the wavelength, the less the number of wave cycles per second.

At constant temperature and pressure, 5.0 L of SO2 is
Ne4ueva [31]
I've done this a few times and keep coming up with 5.0 L . I used the mole ratio, and SO 2 as the LR. That would make 2 moles of SO3 5.0 L but its not one of your choices. the temp and pressure are constant, so according to n/v = p/rt the volume is the same as the moles. hope this helps

Compare the change in pH with the addition of acid and base to deionized water and to a buffer.
iogann1982 [59]

Answer:

case1.

The addition of acid and base leads to a change in pH of the water when adding to deionized water due to fact that acid and bases dissociated in dissolving in water. If the H+ ion increases in the water as acid addition hikes it, it will result in decreasing the pH value. The intensity of the acid also affects the dissociation of the ions.

case2

Buffers are normally formed by weak acid and its conjugate base, and adding acid to the buffer it absorbs the H+ ions so the pH will be lower and adding base or increase of OH- conjugate base resists the pH value to increase.
