Please help me....I have put this question up before but I still dont know....PLease help me someone!
Th
1. The oxidation number is:a. the number of oxygen atoms an element bonds withb. the positive or negative charge acquired by an atom in a chemical bondc. the number of electrons involved in a chemical
hetero is where you can see all the different parts that make up that one thing while homogenous you cant
hetero example: salad ( you can see that its made up of lettuce, tomatoes, etc)
homogenous e
Please correct me if I am wrong:
IUPAC Name: 2,2 - dimethylbutane
- 2,2 means the location of carbon with side chains
- dimethyl represents the side chains (C-C)
- butane is the root chain of carbon
I need help balancing out the following equation through either oxidation number or half-reaction method:
MnO4(aq) + H2O2(aq) + H(aq) ---> Mn(aq) + O2(g) + H2O(l)
(Step by step would be nice as I am
If not, why are they called acids?-Like Sweet Angela says, they are amphoteric. But, like Bird Guy says, They have various side chains.
Their general formula is HO2C-CHR-NH2. They are called acids b
A balloon has a volume of 0.138L and contains 0.0106 mol of CO2. How many grams of CO2 must be added to expand the balloon to 2.00 x 10^2 mL? Assuming ideal gas and STP. Please let me know the formula
Please provide an explanation as I have a test on this tomorrow and I will choose the best answer, thank you.
Identify each of the following as being true of acidic or basic solutions at 25 degrees
At any given temperature, molecules will have the same average kinetic speed.-The Kinetic Molecular Theory explains the forces between molecules and the energy that they possess.
Solids hold there shape and volume. May be crystalline, molecules vibrate in place
Liquids take the shape of the container but hold their volume, pour, molecules can move within the liquid
Gases take
Energy required = Mass of Aluminium x Specific heat capacity of Al x Change in temperature
Energy required = 55 x 0.897 x 72.2
Energy required = 3562 Joules of energy

Please help me I have no idea!!!!Thank you all in advance!-to answer your magnesium ion question :
since an electron has a charge of -1 .. if we gain an electron we have a charge of -1
and if we los
The short answer?
Fission = splitting of atoms
Fusion = joining of atoms
In both cases, we use both to capture the insurmountable radiation energy emitted as a result of the process(es).-Fission is t
What is the atomic weight of one mole of CH4?
How many moles in 64 grams of CH4?-Molecular weight CH4 = 12 + 4X1 = 16 amu = 16 g/mol
64 g / 16 g/mol = 4 moles CH4-One mole of CH4 has a mass of 16.0
Is there a certain way to find out how many bonding sites an element has? Like a formula?
If Hydrogen has an atomic mass of 7 how many bonding sites would it have? From other sites I have seen it sa
