In the given molecule there are 2 carbon atoms.If there are 4mol of the given molecule,then there will carbon atoms twice as that amount.So the answer is 8mol.
What is the toxicity level of bromine?-concentrations of 12,000 ppm caused immediate eye irritation in volunteers and 5 minutes at 6,500 ppm resulted in eye irritation, headache, and vertigo [Sayers a
please explain-the atomic number of an element is the number of protons in the neucleus.
This is what defines the element.eg, If there are 6 protons then the element is carbon. If there are 7 protons
what causes it to boil why does water bubble when it gets to a certain temperature.-Air molecules exert pressureon the surface of the water molecules, this reduces the momentum of the atoms within the
Please help! I got 4-ethyl-5-methyloctane but this doesnt seem right-Well, did you draw it out?
Wait, that doesnt even quite make sense. I cant follow how the structure goes. Have another look at you
phosphorus reacts with oxygen to produce different types of oxides. one of these oxides is formed when 1.347 g of p reacts with 1.744 g of o. what is the simplest formula of this oxide? name the oxide
It looks just like a lower case u only the left side hangs down more. It is used in the following way in a chemistry problem:
According to air quality standards for carbon monoxide in the u.s., the ma
How many moles of chlorine atoms are present in a 9.2 x 10 ^ -2 gsample of zirconium(IV) chloride, ZrCl subscript 4?
Please step by step explanationsand answers please please thank you so much -1 mol
Potassium Bromide + Lead II Nitrate
I know its PbBr2 + KNO3 but how do you set up the the original compounds and do double replacement?-In the reactant side of the equation you will need to turn the
ok, H2 = brown ms, He = blue ms
mix them together so that the brown and blue colors are distributed throughout the container without having one of the colors concentrated in one or more areas.
its th
How do you show that this equation:
Molar Mass = (Kf * mass of solute(g) ) / ( mass of solvent(kg) * delta T)
results from this equation:
delta T = Kf * m * i
I cant seem to put stuff together. A
A) [H+] = 1 * 10^-6M
B) [H+] = 0.00010M
C) [OH-] = 1 * 10^-2M
D) [OH-] = 1 * 10^-11M
Thanks!-These are all pretty easy.pH = -log[H^+]
Put the value for the [H^+] in your calculator and press the log
From what Ive seen they look pretty similar, so whats the difference?
Am I correct in saying that a phenyl is the same as a benzene where one of the Hs has been replaced with another functional group?
This requires a two-step conversion. We must first use the molar mass of copper to convert the given grams to moles. Then we can use Avogadros # (6.022 x 10^23) to convert the moles to individual atom
The formula of am. carbonate is (NH4)2 CO3 and its molar mass = 96
Moles of am carbonate in 0.417 g= (0.417) / 96 = 0.00434 moles.
Each mole of am. carbonate has 2 moles of ammonium ions
No. of moles
