1. In the balanced reaction: 3CL2(g)+6NaH(aq)+ 5NaCl (aq) +NaClo3(aq) + 3H2O(l). How many grams of water can be produces starting with 23 kilograms of sodium hydroxide?


3Cl2(g)+6NaH(aq)+ 5NaCl (aq) +NaClO_3(aq) + 3H_2O(l)

You're missing something there. The equation isn't complete. NaOH (sodium hydroxide) isn't even listed. The first step in solving any of these problems is to produce a complete, accurate, balanced chemical equation.



2. what is the molar mass of nitroglycerin, C3H5(NO3)3?


"Molar mass" is the same as "molecular weight".

Atomic weight of C ≈ 12. There are 3 of these.
Atomic weight of H ≈ 1. There are 5 of these.
Atomic weight of N ≈14. There are 3 of these.
Atomic weight of O ≈ 16. There are 9 of these.

These are approximate.

Molecular\, weight = 3 \times 12 + 5 \times 1 + 3 \times 14 + 9 \times 16 \approx 227\, \frac {grams}{mole}



3.the thermite reaction is given by: Fe2 O3(s)+ Al2(s). How many grams of molten iron will be produces if 2.29 moles of iron (III) oxide is consumed?


Fe_2O_3(s) + 2Al(s) \rightarrow Al_2O_3 + 2Fe

Although you didn't write it correctly, I did. Remember the first step is to produce a complete, accurate, and balanced chemical equation.

You start with 2.29 moles of Iron(III) Oxide (Fe2O3). From the balanced equation, you can see that you produce 2 moles of Fe for every mole of Fe2O3 that is consumed. Therefore you produce 2 x 2.29 = 4.58 moles of Fe. The atomic weight of Fe is 55.845 g/mol. This is how you calculate the number of grams of Fe:

4.58\, moles \times 55.845 \frac {g}{mol}=255.701\,g



for the Haber process for ammonia production is given by the balanced reaction: N2(g) +3H2(g) forward 2nH# (g). How many grams of each reactant would be required to produce 9.4 moles of product?

answer N2 answer H2


N_2(g) + 3H_2(g) \rightarrow 2NH_3(g)

Here's how to do the question. First you are given that you are producing 9.4 moles of NH3 (the product).
1. Calculate the molecular weight of NH3 (3 hydrogens, 1 nitrogen).
2. From the equation, you need 1 mole of N2 to produce 2 moles of NH3. You produced 9.4 moles of NH3, so you figure out how many moles of N2 that required.
3. Calculate the molecular weight of N2 (2 nitrogen atoms).
4. Multiply the molecular weight (grams/mole) by the number of moles (moles) to get the number of grams of N2

\frac {grams}{mole}\times \frac {mole}{1} = grams

Do the same for H2. Except you need 3 moles of H2 for every 2 moles of NH3 that are produced.



5. which of the following molecules is (are) polar? Carbon dioxide, carbon tetrafluoride, molecular chloride, carbon monoxide, and CH2O.

6. Which of the molecules listed in question 5 is (are) nonpolar?


Polarity means that there is a separation of electronegativity. Carbon and the other atoms mentioned differ in electronegativity. Since all of the compounds listed have atoms that differ in electronegative, the question here is to determine is symmetrical and which are not. Sometimes you have to build models. In this case, they are simple enough that you can figure that out. By the way, I haven't any clue as to what molecular chloride is. Should that have been methylene chloride (CH2Cl2)?

Being polar and non-polar are mutually exclusive. Therefore, if a molecule is polar it can't be non-polar and vice-versa.

By the way, I haven't any clue as to what molecular chloride is. Should that have been methylene chloride (CH2Cl2)?

Or, did you mean Cl2, the chlorine molecule?
