1. Mrs. Neville wanted to make 2.35 glof Caco by reacting CaCl, and MgCO. CaCl, + MgCo. - MgCl, + Caco
a.
How many moles of MgCo will be required to make the 2.35 g of Caco ?
b.
How many moles of MgCl, will be produced when the 2.35 g of Caco is created?

Which of the following best describes the formation of plasma?

Butadiene undergoes a reaction at a certain temperature in the gas phase as follows: 2c4h6(g) --> c8h12(g) the following data were collected for this reaction: time (min) [c4h6] (m) 0 0.36 15 0.30 30 0.25 48 0.19 75 0. determine the order of the reaction and the rate constant. 1st order and k = 4.3x10 -4 s-1 1st order and k = 2.3x10-4 s-1 2nd order and k = 4.3x10-4 s-1 2nd order and k = 2.3x10-4 s-1 zero and k = 4.3x10-4 s-1

When a spring is compressed, the energy changes from kinetic to potential. which best describes what is causing this change?
