In the hydrogenation of ethylene using a nickel catalyst, the initial concentration of ethylene is 1.70 m*l-1 and its rate constant (k) is 0.0018 mol*l-1*s-1 . determine the rate of reaction if it follows a zero-order reaction mechanism.

the rate of reaction turns out to be 0.0018 mol*l-1*s-1

with that in mind, determine the half-life for the reaction using the integrated rate law, given that the initial concentration is 1.70 mol*l-1 and the rate constant is 0.0018 m *l-1*s-1?

Electromagnets coils of wire paper clips picked up 10 3 15 6 20 9 25 12 ms. owens' class was studying magnets. ms. owens showed her students how to make an electromagnet using a nail, a d-cell battery, and plastic coated wire. the students wrapped the wire around the nail and then attached the ends to the battery. when they were finished, they tested their magnets by investigating how many paperclips their magnets could pick up. they also tested whether they could increase the strength of their electromagnets by using more coils of wire. they recorded the class average of their results in the data table seen here. ms. owens asked her students to graph their data in a line graph. how should the students label the x-axis on their line graph? a) size of battery b) number of paper clips c) number of coils of wire d) strength of electromagnet
