Answer:
Explanation:
The <em>equilibrium constant</em> for an <em>equilibrium reaction </em>is the ratio of the equilibrium constant for the forward reaction, Kf, to the equilibrium constant for the reverse reaction, Kr:
- The forward reaction is: A → B, with rate constant is Kf = K₁ and
- The reverse reaction is: B → A, with rate constant Kr = K₂

When you write the reaction in the other reaction, the forward and the reverse reaction are exchanged:
- The forward reaction is B → A, with rate constant Kf = K₂
- The reverse reaction is A → B, with rate constant Kr = K₁

As you see:

Thus, <em>the equilibrium-constant expression for a reaction written in one direction is the </em><em><u> reciprocal</u></em><em>___</em><em> of the one for the reaction written for the reverse direction.</em>
Answer:
Formaldehyde is highly soluble in water.
Explanation:
Formaldehyde is the simplest of the aldehydes (R−CHO) it is an organic compound which occurs naturally with the formula H−CHO. . The IUPAC name of formaldehyde is methanal.
Formaldehyde at room temperature is a colorless gas and the liquid is invisible or like white-water. Formaldehyde has an irritating and very pungent like odour. Formaldehyde is very soluble in water.
Now according to Henry's constant law (3 × 10-5 kPa·m3/mol) Formaldehyde will be very unlikely to volatilize from water.and hence, Formaldehyde is considered to be highly soluble in water.
Answer:
The wavelength of this light is 780.4 nm.
Explanation:
Given that,
The frequency of laser light, 
We need to find the wavelength of this light.
We know that,

Where
is the wavelength of light
So,

So, the wavelength of this light is 780.4 nm.
