Calculate the ph of a solution containing 0.0451 m potassium hydrogen tartrate and 0.028 m dipotassium tartrate. The ka values f
Marina86 [1]

Given buffer:

potassium hydrogen tartrate/dipotassium tartrate (KHC4H4O6/K2C4H4O6 )

[KHC4H4O6] = 0.0451 M

[K2C4H4O6] = 0.028 M

Ka1 = 9.2 *10^-4

Ka2 = 4.31*10^-5

Based on Henderson-Hasselbalch equation;

pH = pKa + log [conjugate base]/[acid]

where pka = -logKa

In this case we will use the ka corresponding to the deprotonation of the second proton i.e. ka2

pH = -log Ka2 + log [K2C4H4O6]/[KHC4H4O6]

     = -log (4.31*10^-5) + log [0.0451]/[0.028]

pH = 4.15

The “fatal flaw” in Rutherford’s model of the atom was the idea that if the electrons were ________.
Wittaler [7]
The correct option is A. Rutherford model of the atom consider an atom to be made up of a central nucleus with electrons orbiting around it. The nucleus is considered to be tiny, heavy and its positively charged while the electrons are negatively charged. The shortcoming of this model is that it was not able to explain how the positive nucleus was not able to attract the negative electrons and pull them inside the nucleus.

Select all the correct answers.
pantera1 [17]

Answer:

The correct answer is the charges of the positive and negative copper ions cancel each other out.

Explanation:

A copper metal having no net charge means that it is a neutral atom. A neutral atom means that total number of protons is equal to the total number of electrons.

Explain the difference between ecosystem, community, and population.
Studentka2010 [4]

Out of the three you gave ecosystem is what I would call the most broad. An ecosystem includes living AND non-living things in an area

Community is all the LIVING things in an area (plants are included and I think bacteria is too, but I'm not sure)

Population is pretty narrow it just looks at specific species in one area. Population of mosquitoes doesn't include butterflies, if only looks at mosquitoes

Hope this helped!
