Niacin, one of the B vitamins, is a monoprotic acid. A 0.020 M solution of niacin has a pH of 3.26.What is the acid dissociation constant, Ka, for the ionizable proton?-Niacin is nicotinic acid and it
Sodium nitrite (NaNO2) and sodium benzoate (C6H5COONa) are both used as food preservatives.If solutions of these two salts of equal molarities are compared, which will have the higher pH?(Ka (HNO2) =
ph is a measure of H+ ions the higher up the scale the more of these ions
1-6 are bases like soap 7 is neutral like water and 8-14 is acid like ammonium... but sometimes they say 1-7 and 7-14 just as
Can anyone please help me to find the molecular formula for this problem?? Ill give ten points thanks!?
A 3.000g sample of a gaseous compound was found to contain 2.560g of carbon and 0.440g of Hydrog
we made experiment in our class and we found ot that when you burn:
Potassium Chloride is purple
Sodium Chloride yellow
Barium Chloride green
Calcium Chloride orange
Lithium Chloride red
And now comes
How many GRAMS of bromine are present in 2.12E+21 molecules of carbon tetrabromide ?-carbon tetrabromide --> CBr4 --> 4 atoms bromine per molecule
if 2.12E+21 molecules --> 8.48E+21 atoms of bromine
i got a normal thermometer and put it in a cup of boiling water (God im stupid!).
the thermometer broke because of the immense heat and the mercury spilled. the water was really hot and i bet the merc
Heres the question
Calculate the percentage composition of iron(II) nitrate 6-water Fe(NO3)2.6H2O, otherwise referred to as iron nitrate hexahydrate - the normal form of iron(II) nitrate hexahydrate
how can you tell that C6H1206 is a molecular compound?-compounds that are molecular are composed of atoms right of the zigzag (gases), and also hydrogen.
compounds that are ionic have a metal and nonm
What volume (in mL) of a 0.6758 M solution of CaCl2 contains 1.934 g of the solute?
Do not include units in your answer.-0.6758 M means that there are .6758 moles of this CaCl2 in 1000 ml of solution.
When copper was exposed to air and heated, it was found that the black compound formed has a copper-to-oxygen mass ratio of 4:1. The experiment was repeated several times and gave the same results. Pl
CH3(CH3)CHCHCHCH3-1,methyl pent2-ene-you numbering from the side nearer to double bond then you can do it easyReport Abuse-4-methylpent-2-ene.
Am assuming your molecule looks like this:

For my answer, I had 5.0000x10^4.
Reason: All the numbers are significant. Therefore, the numbers must be represented, right?
To check, I searched and found diff
Consider the sodium atom and sodium ion
a) write the chemical symbol of each
b) do these particles have the same number of nuclei?
c) do they have the same number of protons?
d) could they have differ
a. The number of electrons are lost
b. The number of electrons gained
c. Electrons in the highest occupied energy level of an atom
d. Electrons in the lowest energy level of an atom-I would say c.
