What are the compounds found in nh3?
NH3 is its own compound.The elements in NH3 are nitrogen and hydrogen.
Is NH3 a hydrocarbon?
No, hydrocarbons contain carbon (C) and hydrogen (H) NH3 is a compound of nitrogen and hydrogen.
How do you balaance N2 H2 --------------- NH3?
Put a 2 to NH3 first.Then a 3 to Hydrogen.
What is the molecular mass of NH3 when The atomic mass of N is 1401 gmole and the atomic mass of H is 1008 gmole?
Molecular mass = sum of all atoms masses = 1(molN/mol NH3)*14.01(g/mol N) + 3(molH/mol NH3)*1.008(g/mol H) = 17.03 g/mol NH3
Which is heavier NH3 or H2S Which one can be smell first?
Hydrogen sulfide (H2S, 34g/mol) has a higher molar mass than ammonia (NH3, 17g/mol), so if equal volumes of both gases were released in the same physical area, you would be most likely to smell the ammonia first because it's lighter and would be carried along through the air more quickly by diffusion. Also, if both gases were in a balloon with a tiny hole in it, the ammonia would effuse out more quickly than the hydrogen sulfide, again, because of the lower molar mass.
What is the prercent by mass of hydrogen in NH3?
The formula shows that there are three times as many atoms of hydrogen as of nitrogen in the compound. The gram atomic masses are 1.00794 for hydrogen and 14.0067 for nitrogen. Therefore, the percent by mass of hydrogen in the compound is 100{[3(1.00794)]/[3(1.00794) + 14.0067] or 17.7553 %, to the justified number of significant digits.
How do you calculate the percent by mass of NH3?
Grab yourself a periodic table and look up the atomic masses of nitrogen and hydrogen, which are the constituent elements of NH3 (which is ammonia.) Nitrogen is 14, and hydrogen is 1. Now look at the formula. It says you have 1 nitrogen and 3 hydrogens. Add it up: 14+1+1+1=17, for a total "molar mass" of 17 grams per mole. Now use the concept of percent (part divided by total) to get your percent composition by mass. 14/17=0.82, 82% nitrogen. 3/17=0.18, so 18% hydrogen. You can do that now for any compound!
How many grams of H2 are needed to produce 14.59g of NH3?
The atomic mass of hydrogen is 1.008 and that of nitrogen is 14.007. Therefore, the ratio of the mass of hydrogen to the total mass of NH3 must be 3(1.008)/[14.007 + 3(1.008)] = 0.17756. The mass of hydrogen in the stated amount of ammonia must therefore be 14.59(0.17756) = 2.591 g, to the justified number of significant digits.
What is the mass percentage of N in NH3?
Nitrogen has an average atomic mass of about 14 while hydrogen has an average atomic mass of about 1, so the total molecular mass of NH3 is about 17. From this we find that the mass percentage of N in NH3 is about 14/17 = 82%. To get more precise numbers, look up the exact atomic masses from a periodic table.
What molecule can form hydrogen bonds with others like it?
NH3
What are the compounds found in nh3?
NH3 is its own compound.The elements in NH3 are nitrogen and hydrogen.
What is the mass percentage of hydrogen in ammonia?
The formula for ammonia is NH3, and to a reasonable approximation, the atomic weight of hydrogen is 1 and that of nitrogen is 14. Therefore, the % hydrogen = 100(3/17) = 18 %.
Does NH3 have London interactions?
NH3 is polar compound.There are hydrogen bonds.
How many moles are in 4.00g of NH3?
molar mass=NH314+3=17moles=give mass /molar mass400 / 17=23.5294
How many moles of NH3 are present in 107.1g?
Moles = Mass / Molar Mass 6.155172414= 107.1/17.4
Is NH3 a hydrocarbon?
No, hydrocarbons contain carbon (C) and hydrogen (H) NH3 is a compound of nitrogen and hydrogen.
How many grams of H2 are needed to produce 13.14g of NH3?
The balanced equation for the formation of NH3 is N2 + 3 H2 --> 2 NH3. 13.64 grams of ammonia is equal to .801 moles. Then 1.2015 moles of hydrogen are needed, or 2.42 grams.
