A company desires to produce nickel from refining nickel oxide and sulfide ores. The first step of the process will produce a nickel carbonyl gas Ni(CO4) by heating the ore. The second step is as follows: Ni(CO4)(g) Ni(s) + 4CO(g)

What effect on the process would be caused by increasing pressure?

There would be no effect on this particular reaction.

Ni would be produced at a lower rate.

Ni would be produced at a higher rate.

Which of the following shapes would represent a molecule with two bonded atoms and 3 lone pairs on only one of them , trigonal planar , bent , trigonal pyramidal , linear

+= + + balance the equation on coefficients, ex. 1,1,1

4al + 3o2 → 2al2o3 what does the "3" in front of o2 stand for? a) it indicates that there are 5 oxygen atoms after you add the coefficient and the subscript. b) it indicates that that there are are total of 6 oxygen atoms all bonded together as a single molecule. c) it indicates that there are 3 oxygen molecules chemically bonded to each other in the reaction. d) it indicates that there are 3 separate oxygen molecules in the reaction.
