They tend to form ionic bonds by losing electrons.
Answer:
molarity 0.1
Explanation:
mass of copper nitrate =2.4
no of moles exist in 120ml= 2.4/187.5=0.0128mole
molarity =.0.0128/.12=0.1m
Hello!
First, HNO₃ dissociates in the following way:
HNO₃(aq) → H⁺(aq) + NO₃⁻(aq)
Next, there is a neutralization reaction with Methylamine:
H⁺(aq) + CH₃NH₂(aq) → CH₃NH₃⁺(aq)
Finally, the formed methylammonium ion weakly dissociates in the following way:
CH₃NH₃⁺(aq) + H₂O(l) ⇄ H₃O⁺(aq) + CH₃NH₂ (aq)
From this sequence of reactions, we can see that the resulting solution would be slightly more acidic than the initial one, as the buffer solution resists the addition of strong acid.
Have a nice day!
Answer:
The energy of a wave is inversely proportional to the wavelength of the wave.
As wavelength increases, the energy of the wave decreases.
As wavelength decreases, the energy of the wave increases.
Explanation:
The energy of a wave is directly proportional to the wave's frequency. As frequency increases, so does the energy of the wave.
(energy 
is proportional to frequency 
)
<u>How is this related to wavelength?</u>
Frequency is inversely proportional to wavelength. That means that as frequency increases, wavelength decreases and as frequency decreases, wavelength increases.
(frequency is inversely proportional to wavelength 
)
Therefore, as wavelength increases, the energy of a wave decreases and as wavelength decreases, the energy of a wave increases.
<h2>Answer:</h2>
<u>Most porous is gravel</u>
<h2>Explanation:</h2>
Porosity tells us how much water rock or soil can retain. It tells us about the spaces among the grains. Gravel is more bigger than sand or silt. Its grains are arranged in such a manner that their integral spaces are very bigger so they are more porous. Clay is the most porous but since it is not mentioned in the option so after clay comes the gravel. Usually gravel and sand has equal porosity.
