Ammonia has one unshared pair of electrons, water has two. In our part of the universe, the more unshared pairs you have, the stronger the acid you are (Look at the next one - HF)

The phenyl...

What math operaton gives you the DIFFERENCE between two numbers?

From the weight of the water, you can determine the volume of the flask. When you know the weight of the gas you now have all the data to determine the molecular weight.

PV = nRT

Read the question again. The volume expelled is AIR: volume here is a measure of the amount of air - - the n in PV = nRT.

Solve using those numbers and you will get the Temperature.

Why not, as you suggest, oil and water?
(What are you going to keep it in?)

As the salt of a weak acid, bicarbonate is a weak base. In the presence of a strong base (OH-) it can act as an acid, but as far as your mouth is concerned it has no acidic properties whatsoever....

Phenols are not acidic enough to react with bicarbonate. This is a diagnostic test to distinguish them from carboxylic acids.

I was mistaken. It is balanced correctly.

5 NaClO2 + 4 HCl = 5 NaCl + 4 ClO2 + 2 H2O

What you really need is a correctly balanced equation.
This one isn't.

The trihalo substituent is a good leaving group and dominates further reactions progress.

I think you mean a CARBOHYDRATE.

A gas has a MUCH lower density than does a liquid.
Picture two balloons - one filled with water, one blown up with air. The water filled balloon is much heavier, correct? The balloon filled...

You must realilze that, in one case, you are looking at a gas and in the other you are looking at a liquid. 18 mL of liquid water is 1 mole, 22,400 mL is 1 mole of water vapor. Quite an expansion,...

Read about Avogadro's Law.
Essentially, the volume of a gas depends only on the number of the particles of which it is composed. The hydrogen and oxygen become water molecules and that determines...

This reaction yields an equillibrium between acetic acid (CH3CO2H) and peracetic acid (CH3CO3H)

Hypophosphorous acid is HOP(O)H2, I'm not sure how to get any less sulfur.

This is due to the thermal excitation of the sodium ions by the heat of the flame.

You see this in yellow sodium vapor street lamps and in yellow fireworks displays.

Look in the index to your textbook under "Bronsted / Lowery", You'll find it there.

We won't give you the answer, but Iron in hemoglobin is centered in a Porphryin ring. Look for other porphryin compounds and you will find it. Let's leaf it at that.

What do non-volatlie solutes do to the boiling point of a solvent?
You must have been told or you wouldn't be asking.

No, the equation has water as both a reactant and a solvent.
(It's not balanced correctly,)

This would be an Aldehyde, aka RCHO.

It's the right place! The oxidation number of sulfur is +6, the others are normal.

There is compressed gas at the top of the container above the liquid. This is rapidly discharged -- in less than a second (POP! ).

Then there is a flood of gas as the now unpressurized liquid...

0.381 x Mass = 4.94
Now you do the rest.

M1v1 = m2v2

Hint: Carbon is the center atom.

You won't find the graph on the internet - your stove is different from others, your pots will be too. Draw the graph with Water Temperature on the Y (vertical) axis and with Heating Time on the X...

I wouldnt' take stuff, I'd take knowledge. How to make sulfuric and nitric aicd and toluene and glycerine. How to make iron and turn it into steel. Even aspirin will get you browinie points. ...

I'm an Organic chemist, and one of it's benefits is that I don't have to work with Phys Chem problems. Post this one as a new question.

I'm not sure what the "two conformatons of the carbonium ion" would be. The carbocation is planar. A base (the conjugate base of your catalytic acid for instance) will remove a proton from one of...

OK, now do the same thing to methylcyclopentane. Now you can eliminate any one of 5 different H atoms and make a differnet C+ ion.

There are SO MANY (dozens of) possibilities. Is there more to your question?
C6H12 (the conjugate acid of your carbocation) must have a double bond or be a cyclic molecule. Draw a candidate, lose...

Don't you think HOW MUCH baking soda will make a difference?

You have to learn how to use the Periodic Table. It's your friend for this and many other tasks in Chemistry.

Reactivity increases as you go down the column of the alkali metals.

A sodium atom has 11 protons and 11 electrons and hence has zero charge. Your book says that it can lose 1 electron and thereby become an ion with a plus one charge.
Don't confuse the future with...

Thanks, Judy. I was going to say it makes Hydrogen and Zinc Folate.

Get your Perilodic Table
Find Calcium and Chlorine.
What charges do their ions take?
What is the formula of the resulting compound?

Now you must use your knowledge of Chemistry to prove that the compound in hand has the identity you think it is. This may be easy, it may be difficult. What are you dealing with?

I'm not sure exactly what you are asking -- do you want to know if your predicted products are correct, or if the product actually obtained is correct?

An acidic medium assures that carbonates (from atmospheric CO2) will not form.

In 100 grams of crystals, how many grams of FeSO4 do you have? How many moles?
How many grams of H2O do you have? How many moles?
Divide moles of H2O by moles of FeSO4 and you have n.

I'd say -- the same way as without the indicator.
Not sure I understand.

Let's see: Hydrogen is H2, so C2H4 + H2 ---> C2H6!!

Since your concentrations are only good to 1 significant figure, I think you can ignore the acidity of the acetic aicd - it just doesn't add a significant amount of protons.
So all it does is dilute...

HNO3 is miscible with water. You can add as much as you dare: concentrated nitric acid gets nasty. You can have red fuming nitric acid or white fuming nitric acid as it gets nearly pure.

Of all the amino acids, you've picked glycine - the only one with no side chain. (Hydrogen doesn't count.)

NaHSO4 is the conjugate base of sulfuric acid but is very nearly a strong acid in it's own right. So what you saw is the typical Bicarb / acid reaction producing CO2 gas.

How many things are in 1 mole? Too mamy to count, so we weigh them. How much does 1 mole weigh?
From here it is just simple algebra. You can do it.
