We are covering the periodic table now in science. if I had to make a quick guess it would be that neurons are neutral so they Balance out the protons. it is just a guess so just warning. I hope this helped you in some way
Take two plants - ensure that both get the same amount of sunlight, but one will get little water and the other more water. Water would be the manipulated variable; the sun would be the independent variable and there is only one control. (1) make an observation; “water makes plants grow.” (2) draft the hypothesis “...if____ the ____.” (3) conduct the experiment; (4) gather the data; (5) Do the analysis to support or deny your hypothesis; and (6) repeat if necessary.
I know this isn't the answer but here's an English translation
<span>The saturated vapor pressure of pure water at 20 ° C is 18 mmHg. If at the same temperature as much as 120 grams of x-substance dissolved in 990 grams of water, the vapor pressure of the solution becomes 17.37 mmHg, calculate the relative molecular mass of the substance x?</span>
Resultant aqueous solution of a hydrogen oxalate salt is basic in nature.
<h3>What is pH?</h3>
pH scale is used to determine the acidity, basicity or neutral nature of any solution.
- Values from 0 to 6.9 shows the acidity.
- 7 shows the neutrality.
- And 7.1 to 14 shows the basicity.
Chemical equation for the given salt in an aqueous solution will be shown as:
NaHC₂O₄ + H₂O → NaOH + H₂C₂O₄
From the equation it is clear that reaction produces-
- NaOH which is a strong base and
- H₂C₂O₄ oxalic acid which is a weak acid.
So that resultant solution is basic in nature.
Hence the aqueous solution of salt is basic.

Isotopes are forms of the same elements which contain equal number of protons but different number of nucleus in their nuclei, thus the differ in relative atomic mass but they have same chemical properties. The mass number is the summation of number of proton and number of neutron of an atom. If the mass number is known, then one need to know the number of proton in the atom in order to calculate for the number of neutron.
