If 64 grams of methanol (molar mass 32 g/mol) is combined with 44.8 liters of oxygen, measured at STP, the number of moles of carbon dioxide which can be produced is
(A) 0.66 moles
(B) 1.3 moles
(C) 1.5 moles
(D) 4.0 moles

Consider the four elements above. which one of these elements will combine with oxygen in a 1: 1 ratio?

A4.86 g piece of metal was placed in a graduated cylinder containing 15.5 ml of water. the water level rose to 17.3 ml. what is the density of the metal. i need the steps of how to solve it to so i can use a formula to work out other problems.

Element j is 1s 2s 2p 3s . (i) how many unpaired electrons does j have? (ii) is j a good oxidizing agent or a reducing agent? (iii) state reason for the answer.
