a 5 g packet of effervescing stomach antacid contains 2.68 g of calcium hydroxide to neutralize stomach acid. What volume of stomach acid (containing 0.010 mol/L HCL) could be neutralized?-First start
For my chemistry homework theres a question that asks to List four different substances in each of the three states of matter. In the reading it explains what a substance is (a particular matter with
Which reactions are oxidation or reduction?
1. Na -> Na^++1e^-
2. Zn^2++2e^--> Zn
3. O2 + 4H^++4e^-->2H2O
4. Fe^2+->Fe^3++1e^-
Im not sure how to solve these, any help would be greatly appreciated.
How would you use the solubility rules to separate the following pairs of ions? In each ease indicate what reagent you would add and write the net ionic equation for the precipitation reaction: (a) le
I need to identify bands A through L.
Here is the IR spectra: http://xs.to/storage/anonym/2011/08/22/102601.jpeg
So far I have this:
A – Arene @ 3030 or Alkene @ 3020-3100B - Alkane 2850-3000C – C
So if you can find it on the periodic table then it is an element.
If it is not on the periodic table it is a compound. (Nevermind about the hetero and homo mixtures)
Example
Iron - Element.
Carbon Di
I need help with gravimetric analysis! So I need to find the identity of a Group 1 Metal carbonate by gravimetric analysis. A solution of calcium chloride was added to the carbonate solution to precip
(A) Homogeneous Mixture, (B) Heterogeneous mixture, or (C) Compound.
Personally Im leaning towards Homogeneous Mixture. Thoughts?-Yes, a solution is by definition a homogeneous mixture.-Greg, didnt
The suffix Mono, means one, so there is a single atom, but a compound consists of equal to or more than two different types of atoms that are chemically combined to make one soluble solution.
Thus, y
Automotive air bags inflate when sodium azide, NaN3, rapidly decomposes to its component elements.
2 NaN3(s) 2 Na(s) + 3 N2(g)
(b) How many grams of NaN3 are required to form 16.0 g of nitrogen gas?
In addition to determining elemental composition of pure unknown compounds, combustion analysis can be used to determine the purity of the known compounds. A sample of 2-naphthol, C10H7OH, which is us
Which two formulas represent Arrhenius acids?
A. CH3COOH and CH3CH2OH
B. HC2H3O2 and H3PO4
C. KHCO3 and KHSO4
D. NaSCN and Na2S2O3
And how do you solve these kinds of questions?-Choice B is your an
hello, i will be taking organic chemistry+lab this upcoming fall. my professor suggests on purchasing an organic lab techniques book (costs about $100 and student budget). i was wondering if this is r
Which two formulas represent Arrhenius acids?
A. CH3COOH and CH3CH2OH
B. HC2H3O2 and H3PO4
C. KHCO3 and KHSO4
D. NaSCN and Na2S2O3
How can you tell which ones give off H+ ions?-B. HC2H3O2 and H3PO4
