A solution is prepared at that is initially in benzoic acid , a weak acid with , and in sodium benzoate . Calculate the pH of th
Kisachek [45]

Answer:

pH=4.1

Explanation:

Hello,

In this case, for a concentration of 0.42 M of benzoic acid whose Ka is 6.3x10⁻⁵ in 0.33 M sodium benzoate, we use the Henderson-Hasselbach equation to compute the required pH:

pH=pKa+log(\frac{[base]}{[acid]} )

Whereas the concentration of the base is 0.33 M and the concentration of the acid is 0.42 M, thereby, we obtain:

pH=-log(Ka)+log(\frac{[base]}{[acid]} )\\\\pH=-log(6.3x10^{-5})+log(\frac{0.33M}{0.42M} )\\\\pH=4.1

Regards.

how many grams of water can be produced the combination of 10 grams of oxygen and 8 grams of hydrogen
Nikitich [7]

Answer:

Mass =  11.16 g

Explanation:

Given data:

Mass of hydrogen = 8 g

Mass of oxygen = 10 g

Mass of water produced = ?

Solution:

Chemical equation:

2H₂ + O₂         →      2H₂O

Number of moles of hydrogen:

Number of moles = mass / molar mass

Number of moles = 8 g/ 2 g/mol

Number of moles = 4 mol

Number of moles of oxygen:

Number of moles = mass / molar mass

Number of moles = 10 g/ 32 g/mol

Number of moles = 0.31 mol

now we will compare the moles of hydrogen and oxygen with water.

                   O₂          :           H₂O

                    1            :             2

                  0.31         :            2/1×0.31 = 0.62

                  H₂           :            H₂O

                    2            :              2

                     4            :              4

Number of moles of water formed by oxygen are less this it will act as limiting reactant.

Mass of water:

Mass = number of moles × molar mass

Mass = 0.62 mol × 18 g/mol

Mass =  11.16 g

bogdanovich [222]

Answer:

<em>In the given question Brianna is trying to make a </em><em>whole figure by combining different  single elements.</em>

Explanation:

Here are the different  coloured that are used to join and make one piece this method that Brianna is following is called synthesis.

The combination here is of simple substances that are combined directly to make a complex compound. The compound formed is complex while the substances that combined together can be element or compound  or a combination of both.

Rank these photons in terms of increasing energy:<br> (b) red (λ = 660 nm);
Rama09 [41]

The order of increasing energy is red, yellow, and blue

In physics for a given wave function, the wavelength is defined as the distance between two consecutive points in the waveform. Light is considered a wave and a particle. White light can split into colors of different wavelengths.

The wavelength of visible light ranges from 300 to 700 nm comprising the color VIBGYOR. Wavelength is calculated by the formula velocity divided by the frequency.

If the frequency of the given form is high, then the energy is also high.

brainly.com/question/10750459

#SPJ4

Rank the following photons in terms of increasing energy: (a) blue (λ = 453 nm); (b) red (λ = 660 nm); (c) yellow (λ = 595 nm).

As the frequency is inversely proportional to the wavelength, the energy is also inversely proportional. A higher wavelength will have lower energy.
