7) What is the hydrogen concentration of a solution with a pH of 2.1? *
lesya [120]

Answer:

Hydrogen concentration = 7.94×10^-3 M

Explanation:

from potenz Hydrogen ( pH ) definition

pH = -log[H+]

2.1 = -log[H+]

2.1/-log = -log[H+]/-log

10^-2.1 = [H+]

[H+] = 7.94×10^-3M

Classify these substances? More than one answer may apply in each case.
dalvyx [7]

Answer:

N2 element, pure substance

O2 element, pure substance

N2O Compound, pure substance

Air  (mostly N2 and O2 ) homogeneous mixture

Explanation:

N2, Nitrogen is known as the chemical element that is characterized by having atomic number 7 and that is symbolized by the letter N, in its molecular version, it is recognized as N2.

O2, Oxygen is the chemical element of atomic number 8, this molecular form is composed of two atoms of this element.

A chemical element is a type of matter, consisting of atoms of the same class.

N2O, Nitrous oxide is formed by the union of two molecules of nitrogen and one of oxygen, which is considered a chemical compound since it is a substance formed by the chemical combination of two different elements of the periodic table.

A pure substance is one that cannot change state or divide into other substances, except for a chemical reaction.

Air (mostly N2 and O2 ),  it is a homogeneous mixture of gases that constitutes the earth's atmosphere. A homogeneous mixture is a type of mixture in which its components are not distinguished and in which the composition is uniform and each part of the solution has the same properties.

The formation of condensation on a glass of ice water causes the ice to melt faster than it would otherwise. If 8.00 g of conden
algol13

Explanation:

It is known that heat (Q) required to change the phase of a given sample of mass m will be as follows.

               Q_{f} = mL_{f}    ........ (1)

where,    L_{f} = latent heat of fusion

Similarly,   Q_{v} = mL_{v}[/tex]  ....... (2)

where,     L_{v} = latent heat of vaporization

As it is known that value of latent heat of fusion of water is 334 J/g and latent heat of vaporization of water is 2260 J/g.

Hence, equating both the equations as follows.

          m_{condensation} \times L_{v} = m_{fusion} \times L_{f}

          m_{fusion} = \frac{m_{condensation} \times L_{v}}{L_{f}}      

                         = \frac{8 g \times 2260 J/g}{334 J/g}

                         = 54.13 g

Hence, we can conclude that 54.13 grams of ice will melt.

Explanation:

Photosynthesis is the process by which green plants manufacture their food using carbon dioxide and water in the presence of sunlight.

It is expressed using the equation below;

      6CO₂   +   6H₂O     →      C₆H₁₂O₆  +  6O₂

         reactants                      products

1. Compounds consumed are carbon dioxide and water.

2. Product is glucose and oxygen.

3. Most organism obtain their nourishment directly and indirectly from photosynthetic activities.

Plants are the producers of food in the ecosystem. If the process of photosynthesis does not occur, there is no way other organisms will obtain their own nourishment.
