Substitution Reaction

The question im attempting is as follows: Treatment of 1-iodod-3, 3-dimethylbutane with sodium cyanide (NaCN) in acetone gives as the major product: a. 3,3-dimethylbutanol b. 3,3-dimethylbutanenitri

What is the balanced chemical equation for sodium and nitric acid

2Na + 2HNO3 ---> 2NaNO3 + H2

How do I find Rate(min^-1)

This was collected in a kinetics experiment for the disproportion of A2 in a buffered solution: 3 A2 --> products The generic rate law for the reaction is rate = k[A2]^p [A2]0 : 0.10 Time for Color

Which group of elements is the least reactive

the noble gases-group 8 - noble gases-Noble gasses or inert gasses as they are called.

CHEMISTRY!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

A solution of ethanol (C2H5OH) in water is prepared by dissolving 67.1 mL of ethanol (density = 0.79 g/cm3) in enough water to make 250.0 mL of solution. What is the molarity of the ethanol in this so

A sample of ethanoic acid was found to boil at 121 celcius at atmospheric presssure...

ethanoic acid melting point:16 celcius boiling point :118 celcius use the information in the table to comment on this result-That sample of ethanoic acid contains impurities. Presence of impurities in

Which statement correctly compares the pH of water to that of other substances

A. The pH of water increases as its temperature increases, while other substances have a stable pH. B. The pH of water is neutral; it is higher than the pH of acids and lower than the pH of bases. C.

Does the entropy of the gas increases with increasing temperature

Entropy increases with increasing temperature. But I am confused with the equation, entropy S=dq/T, which shows that temperature is inversely proportional to entropy. Can anyone explain to me? Thanks

Hess's Law?? Calculate the reaction enthalpy/delta H?? Help!!!

1.) Calculate the reaction enthalpy for the reaction.... CH4 (g) + 2O2(g) ---> CO2(g) + 2H2O (l) Use the series of reactions that follow: 1. C(s) + 2H2(g) --> CH4(g) Delta H= -74.8 kJ 2. C(s) + O2(g

Confused about a chemistry question answer!

Im studying for final high school exams and I have a chem exam coming up in the next few days. I was doing the question What is the ph of a solution prepared by mixing 30.0mL of 0.10M nitric acid solu

What is the difference between atoms, molecules, diatomic molecules, and formula units

Please help, I cant find the definitions anywhere in my chemistry book. I have to group these items into their correct group (the numbers are all subscripts): Copper Xenon H2 Ni Oxygen Chlorine HgBr

Which group of elements is the least reactive and why

noble gases (Group 18), they have full electrons on the outer shell.-The inert gases (noble gases) are the least reactive elements.They have completely filled p-sublevels, which is the lowest energy a

What is anhydride in chemistry

p-block elements and experimental chemistry-compound that has lossed it h2O an example is copper sulfate. When it is heated it looses mass and turns white because it is now waterless. Anhydrous meansw

Chemistry 11- easy question about significant figures

Hey, so im supposed to round100.4°C to 2 significant digits. what would it be? thanks soo much!! -1.0X10^2 would be your answer.The .4 is excluded here because it would make there be more sig figs.

Please Help in solving 6 - 1/q = 4? Im really stuck =/

Im really stuck =[-6-1/q=4 add 6 to both sides so -1/q=10 multiply by q on both sides -1=10q and divide by 10 on both sides -1/10=q is your answer-6 - 1/q = 4; subract 6 -1/q = 4-6; then negate 1/
