Explain if an unknown gas takes 2.41 times longer to effuse than methane (CH4) then Define what is the molar mass of the unknown gas
the minimum energy required to cause the photo electric effect in potassium metal is 3.69*10^-19 J. will photoelectrons be produced when light shines on the surface of potassium?if 400 nm radiation is shone on potassium,what is the velocity of the..
Balance the following redox reaction in basic solution. Which of the following statements is not correct? Cr3+(aq) + ClO3-(aq) + OH-(aq) ? Cl-(aq) + CrO4^2-(aq)
Classify each of the following binary compounds by the oxidation number of hydrogen. Drag each item to the appropriate bin. H2O, HCl, MgH2, NH3, NaH, CaH2,H2,CH4 cateogories -1, 1+, 0
How do you determine which methyl group gets the equatorial position in an 1-4 disubstituted isomer? (Assuming the methyl groups are different. For example, one is ethyl and the other is methyl).
A volume of 32.2 mL of a 1.16 M KMnO4 solution is mixed with 17.7 mL of .692 M KMnO4 Solution. Caclulate the concentration of the final solution.
The initial pH of chloroacetic acid is 1.90, (which I found from using the quadratic equation to find x in a RICE table because I was given the initial concentration of 0.124M and told to find the pH of a 10.0 mL solution.)
A 0.411-g sample of potassium hydrogen phthalate, KHC8H4O4 (molar mass=204.44 g/mol) is dissolved with 50 mL of deionized water in a 125 mL Erlenmeyer flask.
starting in the ground state n 1 is a hydrogen atom an electronis excited to a higher energy level by absorption of
About how much phenacetin will remain dissolved when the water calculated (94ml) is cooled to room temperature
the specific heat of silver is 0.24 J/g degree celsius. how many joules of energy are needed to warm 4.37 g of silver from 25 degree celsius to 27.5 degree celsius?
The rate law for the reaction, 2NO(g) + O2(g) -- 2NO2(g), is found to be: rate of reaction=k[NO]2[O2]2 (PLEASE note that the 2's after the concentrations are powers, so we have NO to the power of 2 and O2 to the power of
