We are calculating mols for class, and we need to know atomic mass. I know that the elements themselves have the masses written in their boxes on the periodic table, but how would i calculate things such as NF3 or H2O? (that 2 is small). I need to...

NF3 is a colourless gas which can be prepared from the reaction of ammonia with fluorine. 4NH3(g) + 3F2(g) NF3(g) + 3NH4F(s) According to this equation, what volume of F2(g) at 50°C and 1.00 atm is required to react completely with 4.18 L...

I get it played against me quite a lot and what is the standard response?

This is for mastering chemistry.

Why is the bond angle of nitrogen trifloride(NF3) more than that of phosphine(PF3) ?

1. one 2. no pairs 3. thirteen 4. ten 5. three 6. four 7. two 8. twenty which one is it ? thankz xoxox

Use structural and bonding considerations... Thanks!

1. ten 2. one 3. three 4. twenty 5. thirteen 6. four 7. none 8. two

Is there something to do with their structures and bonding? thanks

Looking for people of high skill and many games who can answer.

i have to 'predict the products' as well as balance these answers

please be detailed in your answer =)

NH3(g) + 3F2(g)--> NF3(g) + 3HF(g) The change in H = -604.8 kJ The change in Hf NH3(g) = -46.19 kJ/mole The change in HfHF(g) = -269 kJ/mole

Need it! it's urgent!

Which ones are polar and which ones are nonpolar?

I already know that NaBr2 and BaS2 are not balanced, but what about the other two formulas? Can they work? Can two gases bond together? Please help!

Why does NCl3 have a larger dipole moment than NF3? N-F bonds are polar and N-Cl bonds are not. Thanks in advance! Does anyone know? Actually I think that the N-Cl bond might be polar, but still, why would NCl3 have a greater dipole moment? The...

N2 + 3 F2 ---> 2 NF3

What molecular structure would be formed by NF3 and what would be the angle measures between the bonds?

I was trying to figure out if the bond angles in NF3 are larger than in NH3. My reasoning led me to the conclusion that they should be larger, though in reality the opposite is true (102 deg for NF3 and 106 deg for NH3). I can't pinpoint ...

working on chemistry and I need to know what NF3 is

Three shared electron pairs in a trigonal planar shape of the molecule. The one unshared electron pair on nitrogen and the pryramidal shape of the molecule. The two unshared pairs on nitrogen and the bent shape of the molecule. The unshared ...

Also can you tell me something about the basic ideas of this opening? What are the key squares that need to be controlled, common mistakes to avoid, plans to follow, etc. Thx!

Please be detailed looking for best moves against all of white's best moves.

Both PF3 and PF5 are known compounds. NF3 also exists, but NF5 does not. Explain briefly why PF3 and PF5 are both possible, but there is no molecule with the formula NF5. help please? i can't seem to figure out why :S thankyou :)

what does the 3 stand for I know it but I can't remember it.

what are the conditions for one of them to have higher dipole moment as these two have similar structures... please explain....

I drew out the lewis dot structure of NF3, and i found it had 10 pairs of lone electrons, but on my review packet it gives me the option of 20 or none of these. Which is it?

PFCs (perfluorinated compounds) vs. FCs (fluorinated compounds)...is there a difference? What do C2F6, CF4, CHF3, SF6, NF3, C3F8 and C4F8 count as?

The molecule BF3 is planar with boron in the center and fluorine atoms forming an triangle. It has triangular planar 120 degrees fluorine-boron-to fluorine bond angles, whereas the NF3 molecule is a triangular pyramid with fluorine-to-nitrogen-to-...
