Im trying to make alcohol from extra bread we have.I found about 3lbs sugar to one gallon of wa
Lool , this is actually a pretty easy question , I think I know the answer .. but Im not sure .
Anyway , could you guys help me :D
so it says : limestone ---------> lime + carbon dioxide. . except on
you can prove it by breaking water down to collect hydrogen and oxygen gas. This is done via electrolysis-An element is an item that has the same atoms throughout (Gold, uranium, silver, potassium, ca
Im trying to convert 10mL of Bromine to grams (g). Normally I would see density a g/mL but Bromines density is described as 3.1028 g/cm(-cubed). How can I convert this amount to grams?-1.0mL is the sa
A simple reaction between Zn2+ and Ammonia NH3 will give me .....Zn[NH3}2+ right??????? and would that be my ionic equation?-I would think it would be [Zn(NH3)4]^2+ and that the ionic equation would b
2NaOH(aq) + H2SO4(aq) → Na2SO4 + 2H2O
and how is it a 2:1 ratio?-The above equation says that youre reacting Sodium Hydroxide with Sulfuric acid to form Sodium Sulfate and Water.
It is a 2:1 ratio b
Ok. This is a true story, it happened not long ago and was one of the weirder things that have ever happened to me. Me and my boyfriend were driving in NSW, in a national park that only really had a r
Question: What is the specific gravity of gasoline given that its density is 0.7 g/mL.
I dont really understand what specific gravity is, or what equation I need to use to solve the problem. Please h
How much heat in kj is evolved in converting 1.00 mol of steam at 145.0 C to ice at -55.0 C? The heat capacity of steam is 2.01 j.gC and of ice is 2.09 j/gc-with sig figs its comes to a total of 58.0
For the following question:
12. Select the equation which represents an ionisation reaction with water.
A. NaCl(s) → Na+(aq) + Cl-(aq)
B. CuBr2(s) → Cu2+(aq) + 2Br-(aq)
C. HBr (g) → H+(aq) + Br-(aq)
D
C[NH4Cl]= 0.1 mol L-1
C[H] = 4/1 x C[NH4Cl]C[H]= 0.4 mol L-1
PH= -log(0.4) =0.4-im afraid thats not correct
after dissolution you have NH4+ and Cl-. only NH4+ is relevant
the concentration is c[NH4+
10th grade AP chem. if anyone could help thatd be awesome.
Sodium hydrogen carbonate, known commercially as baking soda, reacts with acidic materials such as vinegar to release carbon dioxide gas. A
A solution with a pH of 7, or a solution with a pH of 9?
Thats all it says, I was under the impression that the pH doesnt matter in this case, like both solutions could be a good buffer, am I wrong?
