would that mean theyre the same substance?
Just need a little help with HW. My books asking why cant copper and gold have the same intensive properties.. Isnt that just because theyre simply two diff
If the initial temperature of distilled water in a coffee cup calorimeter was well below room temperature, would this in any way effect the experimental result if I was calculating specific heat of an
I have a science prac report and according to the marking scheme, the title above is a dot point. However; i have no idea what to write for it. The errors used are predicted error, experiment error, a
The product of this reaction. please explain. thx..-Cu^2+ + 2OH^- -----------> Cu(OH)2
or, if you prefer,
CuSO4(aq) + 2 NaOH(aq)------------> Cu(OH)2(s)+ Na2SO4(aq)
This is a double displacement reac
help, i dont know how to balance redox reactions. basically because i dont know how to find the oxidation number, i know there are rules but i just dont get it >.
PH(3)+ I(2) ------> H(3)PO(2)^(-) +
Met-enkephalin is one of the so-called endorphins, a class of naturally occurring morphinelike chemicals in the brain.
___
What is the molecular mass of met-enkephalin if 20.0 mL of an aqueous solutio
FALSEThe atomic number is the number of protons in an atom.The mass number is the sum of the number of protons and the number of neutrons in an atom.The number of electrons equals the number of proton
I really dont know how to do this, and i think if someone walks me through one ill get a better understanding of it.Its a Stochiometry/limiting reagent problem. Please and Thank you!
Determine the mas
What is the molarity of Li^2C^2O^4 if 5.00g of the compound is dissolved into 500.0 mL of distilled water?-For future reference, the carat (this character ^) is for writing numbers in the superscript
Calculate the pH obtained by mixing 400mL of .2 M NaOH with 150mL of .1 M H3PO4 (pkas 2.12, 7.21, 12.32)-There are 400 x 0.2 = 80 mmole of NaOH and 150 x0.1 = 15 mmole of H3PO4comlete reaction between
A lead atom has a mass of 3.4X10-²². How many lead atoms are in a cube of lead that has a volume of 2.00cm3 if the density of lead is 11.3g/cm3?-find mass of Lead
(2.00 cm3) (11.3 g / cm3) = 22.6 gram
A 23.2 g sample of ore that contains the mineral corundum is found to contain 14.2 g of aluminum. The element aluminum is 62.776 percent by mass of the mineral corundum. Calculate the percent by mass
Based on the periodic table you know Ga has 3 valence electrons. (Group 13). But since your cation is positive, it has one less electron (electrons have a negative charge).
So your Lewis Dot Diagram
For my chemistry homework, I have been given the isotopes Rubidium-87 (86.91u) and Rubidium-85 (84.91u). I am supposed to determine what the percent abundance of each isotope is in Rubidium, if Rubidi
