Answer the following questions about the chemical reaction: C3H8(g) + 5 O2(g) à 3 CO2(g) + 4 H2O(g)

If 4 moles of propane (C3H8) react, how many moles of carbon dioxide are produced?

a
4
b
12
c
16

you need to have a picture of the atom that way we can answer it

no starving yourself won't it will make you lose more weight what you need to do is find out what foods make you gain weight like bread and meats with fat on

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.
