Hey there!
Na is sodium, which has 11 protons.
The more realistic amount of neutrons for this atom to have is 12. 23 would be the sum of protons and electrons.
The atom has a charge of 1+, so there is one less electron than protons, so
11 - 1 = 10 electrons.
Your answer is d. it has 11 protons, 10 electrons, and 12 neutrons.
Hope this helps!
This problem is providing us with the mass of sulfur dioxide and the molecules contained are required. At the end, the result turns out to be 3.252x10²³ molecules, according to:
<h3>Avogadro's number:</h3>
In chemistry, we use the Avogadro's number in order to successfully perform mole-mass-particles calculations. Defined as 6.022x10²³, it provides the number of atoms, molecules and ions in one mole of the substance.
In this case, in order to obtain the result, one first calculates the moles in 34.61 grams of sulfur dioxide and then utilize the Avogadro's number to obtain the number of molecules as shown below:

Answer:
Explanation:
The Sebacic acid has strong hydrocarbon content which make it insoluble in water. Treating the unknown sample with a base for example NaOH will increase the solubility of the Sebacic acid because the carboxylic acid group will react with the base to form soluble ionic salt. The Sebacic acid is completely dissolved in the base
The resulting solution can be titrated with HCl until there is a color change signifying end of neutralization. The mole of NaOH present before the organic acid is noted, then after titration the mole of the HCl acid is subtracted from the initial mole of the base; this will give the carboxylates present in the solution.
