If 435 grams of water at 23 celcius abssorbs 281 kJ of heat froma mountain climber's stove at an elevation where the boiling point of water is 87 celcius
Describe how biological membranes are organized: what roles do lipids and proteins play in this organization
Assuming STP, how many liters of carbon dioxide are produce when 5.74 g of CaCO3 reacts with an excess of H3PO4
Chlorine gas can be produced commercially by passing an electric current through a con- centrated solution of sodium chloride (brine).
H2s and H20 have similar structures and their central atoms belong to the same group. Yet H2S is a gas at room temperature and H20 is a liquid. Use bonding principals to expalin why this is.
Write a balanced thermochemical equation for the standard formation of CH3OH
How many molecules of carbon dioxide are produced when 129 molecules of acetylene (HCCH) to react in excess oxygen produce carbon dioxide and water.
Express the rate of the following reaction equation in terms of the rate of concentration change for each of the three species involved: 2NOCl (g) = 2NO (g) +Cl2 (g)
