The answer is: 60.
Tobacco products are made up of thousands of chemicals, including at least 60 known to cause cancer (carcinogens).
Some of carcinogens chemicals are: acetaldehyde, arsenic, radioactive elements (for example polonium-210), nitrosamines, nickel, benzene, polycyclic aromatic hydrocarbons, vinyl chloride.
Smoking tobacco causes at least 15 different types of cancer. For example: mouth, pharynx, larynx, oesophagus, liver, pancreas, stomach, kidney cancer.
Because it has molecules of water in it
Fire probably i dont know
The equation for the reaction is as follows;
NH₃ + HCl --> NH4Cl
one of the 2 reactants have been added in excess, to find out which reactant is in excess we need to find the number of moles of each reactant
NH₃ moles reacted - 6.01 g / 17 g/mol
= 0.35 mol
HCl moles reacted = 4.91 g / 36.5 g/mol
= 0.13 mol
the stoichiometry of NH₃ : HCl = 1:1
therefore the number of moles reacted should be equal, however NH₃ there are more moles than HCl which means that NH₃ has reacted in excess
the number of NH₃ moles that would have reacted = 0.13 mol
The mass of NH₃ reacted = 0.13 mol * 17 g/mol
= 2.21 g
the excess amount of reactant is = 6.01 g - 2.21 g
= 3.8 g
the answer is 3.8 g
Molecular is existent due to being made out of molecules, and thus taking up space until a container cannot hold more.
Ionic substances are a little different they are made out of energy, thus taking up only the amount of energy a certain area can handle. Ionic substances also will show motion of energy as well.
