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 best describes the present-day universe? opaque, expanding very slowly, stars produce heavy elements transparent, expanding at an accelerated rate, stars produce heavy elements opaque, expanding at an accelerated rate, stars produce only hydrogen and helium transparent, expanding very slowly, stars produce only hydrogen and helium

Did the detergents containing enzymes work better at removing stains than those containing no enzyme? why or why not?

Benzonitrile (c6h5cn) is reduced to two different products depending on the reducing agent used. treatment with lithium aluminum hydride followed by water forms k, which has a molecular ion in its mass spectrum at 107 and the following ir absorptions: 3373, 3290, 3062, 2920, and 1600 cm-1. treatment with a milder reducing agent forms l, which has a molecular ion in its mass spectrum at 106 and the following ir absorptions: 3086, 2850, 2820, 2736, 1703, and 1600 cm-1. l shows fragments in its mass spectrum at m/z = 105 and 77. propose structures for k and l and choose an explanation for how this could be concluded.
