If 27.3g of C8H18 is combusted, according to the equation below, what mass of water is produced? 2C8H18 + 25O2 --> 16CO2 + 18 H2O,

molar masses: C8H18 = 114.3 g/mol O2 = 32.0 g/mol CO2 = 44.0 g/mol H2O = 18.0 g/mol

How to solve 4 nh3(g) + 5 o2(g) > 4 no(g) + 6 h2o(g) in chemistry

The element that has the greatest electronegativity is

Astudent pours 10.0 g of salt into a container of water and observes the amount of time it takes for the salt to dissolve. she then repeats the process using the same amounts of salt and water but this time she slowly stirs the mixture while it is dissolving. the student performs the experiment one more time but this time she stirs the mixture rapidly. the dependent variable in this experiment is: time for salt to dissolve speed of stirring amount of water mass of salt
