What is the bronsted acid of NO2- + H2O HNO2 + OH-​

Chemistry
1 answer:
sammy [17]2 years ago
8 0
<h3><u>Answer</u>;</h3>

H2O -Bronsted Acid

<h3><u>Explanation;</u></h3>
  • Bronsted-Lowry acids are  H+ donors , while Bronsted-Lowry bases are H+ acceptors .
  • A reaction of a Bronsted-Lowry acid and a Bronsted base is a neutralization reaction that is characterized by H+ transfer.
  • The above reaction is an example of base ionization or dissociation where;

                 B (aq) + H2O (l) → BH+ (aq) + OH– (aq)

          That is; Base + Acid will give a conjugate acid + hydroxide ion

  • In our case; NO2- + H2O → HNO2 + OH-​ ; H2O is the H+ donor and thus, it is a Bronsted Acid.

The graph shows the changes in the phase of ice when it is heated.
kow [346]

Answer:

A) 0 °C, because it is the melting point of ice.

Explanation:

  • Point B is the temperature at which the water is converted from ice (solid phase) to liquid water (liquid phase), which is the melting transition of water.

Melting point of the water is at 0.0°C.

<em>So, the right choice is: A) 0 °C, because it is the melting point of ice. </em>

What is the relationship between atmospheric pressure and the density of gas particles in an area of increasing pressure? As air
Marina86 [1]

We need to know the relationship between atmospheric pressure and the density of gas particles in an area of increasing pressure.

The relationship is: As air pressure in an area increases, the density of the gas particles in that area increases.

For any gaseous substance, density of gas is directly proportional to pressure of gas.

This can be explained from idial gas edquation:

PV=nRT

PV=\frac{w}{M}RT [where, w= mass of substance, M=molar mass of substance]

PM=\frac{w}{V}RT

PM=dRT [where, d=density of thesubstance]

So, for a particular gaseous substance (whose molar mass is known), at particular temperature, pressure is directly related to density of gaseous substance.

Therefore, as air pressure in an area increases, the density of the gas particles in that area increases.

What is the solution to the problem expressed to the correct number of significant figures
quester [9]

I don't know what the problem is, but here are some rues to help you out:

  1. All non-zero figures are significant
  2. When a zero falls between non-zero digits, that zero is significant.
  3. When a zero falls after a decimal point, that zero is significant.
  4. When multiplying and dividing significant figures, the answer is limited to the number of sig figs equal to the least number of sig figs in the problem.
  5. When adding and subtracting, the answer is limited to the number of decimal places in the number with the least number of decimal places.

What will be the boiling point of a solution of 8 moles of sodium dichromate (Na2Cr2O7) dissolved in 8 kg of water? Use the foll
nexus9112 [7]

Answer:

1. 374.69 K

Explanation:

Hello,

In this case, pure water's boiling point is 373.15 K, thus by considering the boiling point increase equation:

\Delta T=imKf

Whereas i=2 since two ionic species are formed,actually, the experimental value is 2.42 so better work with it, thus:

\Delta T=2.42*(\frac{8}{8}m)*0.512 Km^{-1}=1.239K

Thus, the required boiling point is:

T_b=373.15K+1.239K\\T_b=374.69K

Regards.
