Yes h20 can act as an acid or a base depending, if h20 donates a proton it will be a Bronsted lowery acid. If h20 accepts a proton it will be a Bronsted Lowry base. Hope that helps

Firlakuza [10]

Sulfur trioxide (SO3) is a chemical compound that is a significant pollutant in gaseous form as it is involved in the production of acid rain.

Industrially, sulfur trioxide is an important precursor to sulfuric acid and is formed from the reaction between sulfur dioxide (SO2) and oxygen gas (O2) as shown in the chemical equation below.

Consider the following chemical reaction: CO (g) + 2H2(g) ↔ CH3OH(g) At equilibrium in a particular experiment, the concentratio

grigory [225]

Answer : The equilibrium concentration of $CH_3OH$ will be, (C) $2.82\times 10^{-1}$

Explanation : Given,

Equilibrium constant = 14.5

Concentration of $CO$ at equilibrium = 0.15 M

Concentration of $H_2$ at equilibrium = 0.36 M

The balanced equilibrium reaction is,

$CO(g)+2H_2(g)\rightleftharpoons CH_3OH(g)$

The expression of equilibrium constant for the reaction will be:

$K_c=\frac{[CH_3OH]}{[CO][H_2]^2}$

Now put all the values in this expression, we get:

$14.5=\frac{[CH_3OH]}{(0.15)\times (0.36)^2}$

$[CH_3OH]=2.82\times 10^{-1}M$

Therefore, the equilibrium concentration of $CH_3OH$ will be, (C) $2.82\times 10^{-1}$

Why does the sky appear orang or red at sunset and sunrise?

LUCKY_DIMON [66]

Answer:

Because the sun is low on the horizon, sunlight passes through more air at sunset and sunrise than during the day, when the sun is higher in the sky. More atmosphere means more molecules to scatter the violet and blue light away from your eyes.
