consider the law of conservation of mass as you answer this problem. when ammonium nitrate breaks down explosively, it forms nitrogen gas, oxygen gas, and water. when 40 grams of ammonium nitrate explode, 14 grams of nitrogen and 8 grams of oxygen are formed. how many grams of water are formed?

In the year 2007, an estimated amount of 31 billion tons of carbon dioxide was emitted worldwide due to fossil fuel combustion and cement production. Express this mass of carbon dioxide in grams WITHOUT exponential notation, using an appropriate metric prefix.

A gas 'x' is collected over water at 17 degree celcius and 750 mm pressure.If the volume of the gas collected is 50 cc then calculate the volume of the dry gas at standard temperature pressure and at 17 degree celcius the vapour of pressure is 14 mm

A man bought a can of Now spray paint in order to paint "No Parking" on the fence behind his house using stencils. The container had 9 ounces by weight of chemicals in it, including ketones, toluene, and aliphatic hydrocarbons. Obtain a Material Safety Data Sheet (MSDS) from online that lists the composition. To the best of your ability using the information given, compute the average molecular weight. How many moles are in the can? State one source of error that you cannot get around in computing fully correct values.
