Hi can u help me pls? I'm totally stuck . The natural source of acidity in rain water is _____.
kykrilka [37]

Answer-The correct option is option d with says all of the above.

Explanation- All three acids that are given combined together to form acid rain in which nitric and sulphuric acid are stronger acids present while carbonic acid is a weaker one.

The carbon dioxide admitted in air combines with water to form carbonic acid and gives a weak acidic nature to rainwater. Pollution in nature makes sulphur and nitrogen present in air react to form the stronger acids responsible for acid rain.

Calculate the de broglie wavelength of a subatomic particle that is moving at 351 km/s if its mass is 9.11 à 10â31 kg. λ = hmuh
gregori [183]

The de Broglie wavelength of a subatomic particle is 2.09 nm.

 λ = h m v = h

momentum : wherein 'h' is the Plank's steady. This equation pertaining to the momentum of a particle with its wavelength is de Broglie equation and the wavelength calculated the use of this relation is de Broglie wavelength.

Frequency is the ratio of velocity and wavelength in relation to hurry. In evaluation, wavelength refers back to the ratio of velocity and frequency.

Wavelength is the gap between the crests of waves or a person's fashionable mind-set. An instance of wavelength is the gap between the crest of two waves. An instance of wavelength is while you and some other character share the equal standard attitude and might for that reason speak properly.

calculation is given in the image below

de Broglie wavelength λ = h/mv

                                          = (6.626 * 10^-34)/9.1 * 10^-31 *351 *10^3

                                          = 2.07 *10^-9

                                 Hence, = 2.op nm

The value of Ka for phenol (a weak acid), C6H5OH, is 1.00×10-10. Write the equation for the reaction that goes with this equilib
I am Lyosha [343]

Answer:

Ka=\frac{[C_6H_5O^-][H^+]}{[C_6H_5OH]}

Explanation:

Hello,

In this case, weak acids are characterized by the fact they do not dissociate completely, it means they do not divide into the conjugated base and acid at all, a percent only, which is quantified via equilibrium. In such a way, the chemical equation representing such incomplete dissociation is said to be:

C_6H_5OH\rightleftharpoons C_6H_5O^-+H^+

Thus, we can write the law of mass action, which consider the equilibrium concentrations of all the involved species, which is also known as the acid dissociation constant which accounts for the capacity the acid has to yield hydronium ions:

K=Ka=\frac{[C_6H_5O^-][H^+]}{[C_6H_5OH]}

Best regards.

Compare the following sodium atoms in terms of their neutrons and mass numbers 24Na, 23Na​
olga_2 [115]

Na-24 and Na-23 have the same number of atoms=11, different neutrons(13 and 12),different mass number(24 and 23)

<h3>Further explanation </h3>

The elements in nature have several types of isotopes

Isotopes have the same number of protons and having a different number of neutrons.

So Isotopes are elements that have the same Atomic Number (Proton)

  • ₁₁²³Na

number of atoms = 11

mass number = 23

number of neutrons=23-11=12

  • ₁₁²⁴Na

number of atoms = 11

mass number = 24

number of neutrons=24-11=13
