When a 3.80 g sample of magnesium nitride (MW 101g/mol) is reacted with 3.30 g of water, 3.60 g of MgO is formed. What is the pe
lianna [129]
  The  percent   yield  of  this   reaction  is  calculated  as  follows
  Mg3N2  +  3H2O  =2NH3  +  3Mgo

  calculate  the   theoretical  yield,
moles=mass/molar  mass
moles Mg3N2=  3.82  g/100g/mol=  0.0382  moles(limiting  regent)

moles of  H2o=  7.73g/18g/mol  = 0.429  moles ( in  excess_)

by  use   of  mole  ratio   between  Mg3N2  to  MgO  which  is  1:3   the    moles  of MgO =  0.0382  x3  = 0.1146  moles
mass =moles  x molar  mass

the  theoretical  mass  is therefore =  0.1146mole  x  40  g/mol  =  4.58 grams

The %  yield  =  actual  mass/theoretical  mass  x1000

=  3.60/4.584  x100=  78.5%

Why does a candle relight if a match is held above the wick just after the flame is<br> blown out?
shutvik [7]

Answer with Explanation:

A candle relights when a match is held above the wick because its trail of smoke still contains some of the wax. When candles are burned, the heat of the flame turns the the wax (which is originally solid) into liquid (commonly near the wick) and then evaporates as gas. The vaporized wax actually protect the wick and this is the reason why it is not burned. So, when you put off a candle, the vaporized wax is still present near the wick. This, remember, holds heat and light energy. Thus, this explains why the candle can be relighted once you hold a match above the wick. It then allows the match to ignite.

Thus, this explains the answer.

A small container of perfume is opened in a classroom. Soon every student in the room smells the perfume. Explain this in terms
iogann1982 [59]

When perfume or cologne is sprayed into the air, it turns into a gas and its particles mix with other air particles that quickly move around the room. This is because gas is the least dense of the three states of matter. It moves quickly into any space or volume because it has the least density. This is called diffusion, when molecules or particles move from areas with high concentration to low concentration areas.
