Answer:

Carbon dioxide CO

Explanation:

As the relative molecular mass of carbon dioxide (44.0) is greater than air (about 28.0), molecules of carbon dioxide gas diffuse into the porous pots lower than air can diffuse out. This results in a decrease in pressure in the porous pot causing the water level at arm X to rise ininitially.

•The water level at A falls to the original level when the concentration of carbon dioxide and air is the same inside and outside the porous pot, i.e. there is no net diffusion of gases in both direction.

What is the conjugate acid in the following equation hbr + H2O yields h30 positive + BR negative

kirill115 [55]

Answer:

HBr + H2O = H3O+ + Br-

So our conjugate acid is the H3O+ to H2O

Explanation:

A conjugate acid of a base results when the base accepts a proton.

Consider ammonia reacting with water to form an equilibrium with ammonium ions and hydroxide ions:

NH3 (aq) + H2O (l) ⇌ NH4+ (aq) + OH- (aq)

Ammonium, NH4+, acts as a conjugate acid to ammonia, NH3.

In a closed container, the vapor pressure of 10 mL of ethanol at 20 degrees C is 5.85 kPa. What is the vapor pressure of 20 mL o

natulia [17]

Answer:

${P_2}=2.925\ kPa$

Explanation:

At same temperature and same number of moles, Using Boyle's law

${P_1}\times {V_1}={P_2}\times {V_2}$

Given ,

V₁ = 10 mL

V₂ = 20 mL

P₁ = 5.85 kPa

P₂ = ?

Using above equation as:

${P_1}\times {V_1}={P_2}\times {V_2}$

${5.85\ kPa}\times {10\ mL}={P_2}\times {20\ mL}$

${P_2}=\frac{{5.85}\times {10}}{20}\ kPa$

${P_2}=2.925\ kPa$
