If you have 1.8 moles of magnesium and 3.2 moles of chlorine, what is the product of the reaction. what is the limiting regent? what is the Theoretical yield in grams and moles? show work?

You need to add one as there is one extra ridge compared to the number of spacings between ridges

GPE =mgh 240 =5x10xheight height =240/50 height =4.8m Sin 25 =4.8/hypotenuse since hypotenuse is the length of the ramp it can be found from above.

80x10-750 =80a 50=80a acceleration a =5/8 V ssquared = u squared + 2as = 2x 5/8 x 20 = 25 V= m/s

yes

There are 30 stundent in the class.Four fifths of them have brown eyes.How many student have brown eyes

Good
