What is the mass of 2.79 mol of the element
iron (fe)?
answer in units of g.

Ab c or d ? i’m not sure what the answer is

For the reaction c6h14(g) & longrightarrow; c6h6(g) + 4h2(g), δp(h2)/δt was found to be 2.5 x 10-2 atm/s, where δp(h2) is the change in pressure of hydrogen. determine δp(c6h14)/δt for this reaction at the same time.

One similarity and one difference between an element and a mixture of elements
