n Styrene ------------> Polystyrene
Molar mass of Styrene (C6H5CH=CH2) , a monomer = 104 g/mol
Molar mass of polystyrene having 25000 monomeric units = 25000 * 104 = 2.6 * 106 g/mol
When polyacrylonitrile is burned, toxic gases are released. Referring to Table 11.2 for the structure of...
a) Explain the reason why heat is released when a hydrocarbon fuel is burned in a combustion chamber.b) Why excess air is necessary to use in an actual combustion? Explain.c) \(n\) - Dodecane \(\left(C_{12} H_{26}\right)\) in gas form is burned in a combustion chamber with \(150 \%\) excess air.Determine the following:i) the chemical reaction equation showing all reactants and products.ii) the required air to fuel ratio by mass, \(A F_{m}\left(\frac{k g \text { air }}{k g \text { fuel }}\right)\),iii)...
Review Constants Periodic Table Air consists mostly of nitrogen (N), with a molecular mass of 28, and oxygen (O2), with a molecular mass of 32. A water molecule (H,O) has molecular mass 18. According to the ideal gas law (N/ V P /KT), dry air at a particular pressure and temperature has the same particle density (number of particles per unit volume) as humidait at the same pressure and temperature. Consequently, humidair, whose low-mass water molecules replace more massive nitrogen...

ReviewI Constants Periodic Table The air that surrounds us is mostly empty space, and it can be almost a factor of one thousand less dense than water. Within that mostly empty space, gas molecules are moving around at high speed and colliding with each other, and if you are in an enclosed space, they are also colliding with the walls. We can more easily observe the behavior of a gas by confining it to a container with a known volume,...
