A child’s bike containing 5.25 kg of iron rusts according to the thermochemical equation shown here: 4Fe + 3O2 --> 2Fe2O3, Delta H = -1648 kJ

How many kJ of heat will be produced if all of the iron is oxidized? Round your answer to the nearest thousands, such as 25,000. Do not write the units.

When svante arrhenius first proposed his acid-base theory, he was a doctoral candidate. his professors thought his ideas were unfounded. within a decade, the arrhenius theory of acid-base was widely accepted and praised within the scientific world. arrhenius defined acids as compounds having ionizable hydrogen and bases as compounds with ionizable a) barium. b) hydronium. c) hydroxide. d) oxygen.

Asample of ammonia reacts with oxygen as shown. 4nh3(g) + 5o2(g) 4no(g) + 6h2o(g) what is the limiting reactant if 4.0 g of nh3 react with 8.0 g of oxygen? o2 because it produces only 0.20 mol of no. nh3 because it produces only 0.20 mol of no. o2 because it produces two times less no than nh3. nh3 because it produces three times more no than o2.

In saturated organic compounds, all the bonds between carbon atoms are called?
