1. What is the percent yield for the following reaction given we
start with 34.08 grams of ammonia and 96.00 grams of oxygen and
obtain an actual yield of 21.73 grams of nitric oxide?
4 NH3(g) + 5 O2(g) → 4 NO(g) + 6 H2O(g)
2. What is the percent yield for the following reaction given we
start with 32.38 grams of aluminum and 609.12 grams of iodine and
obtain an actual yield of 427.92...
Which statement is correct in regards to percent yield and
theoretical yield?
Percent yield determines the maximum amount of product that can be
expected through mathematical calculations. It is set as a
proportion to the actual yield to compute the theoretical yield.
Together, they are used to determine the reactant that will limit
the reaction.
Percent yield determines the maximum amount of product that can
be expected through mathematical calculations. It is then used to
compute the theoretical yield. Calculating...
For an object that weighs 1000 grams- to get it to
levitate 15 cm above a negatively charged plate it requires extra
electrons.
1) what charge is required to be added to this object?
2) how many electrons would this be?
the only information given for the plate is that it is
negatively charged.
the only information given on the charge of the plate is that it's
negatively charged.

1-Suppose a Styrofoam cup that weighs 5 grams was used
for this experiment in place of the aluminum calorimeter. What
differences in the analysis and results might you expect? The
specific heat of Styrofoam is 0.3 kcal/kg-°C (0.3 cal/g-°C) and its
thermal conductivity is 0.00008 cal/sec-cm-°C.
