_C5H12 +
O2 -->
CO2 +
H20
If 76.50 grams C5H12 added to a previously evacuated vessel where it reacts with
excess oxygen, how many grams of H20 will be produced? Don't forget to include
proper sig figs and units in your answer.

with this one i know the answer in craters one reason i looked it up and i learned about it there is my evidence

nacl or sodium chloride is an ionic compound. this is because an ionic compound pertains to a compound that consists of positively and negatively charged ions. in this case, na (sodium) has a tendency to lose one electron when it reacts with with other atoms, so the resulting sodium ion contains 11 protons and 10 electrons, thus making it positively charged (na+), when chlorine reacts, it usually gains one electron to form an ion called chloride, thus making it negatively charged ( since the ions are oppositely charged, they attract.

weight of any object is given by

w = m*g

where m is mass of the object and g is the acceleration due to gravity.

for earth the value of g is 9.8 m/s^2 so

w=117.6 n m=12 g=?

117.6=12g => g=9.8 m/s^2

which is the force of gravity on earth.
