I recently did an experiment on Aldol Condensation, by reacting Benzaldehyde with Acetone to form Dibenzalacetone. The proposed stoichiometric ratio of Benzaldehyde:Acetone is 2:1. What would be the implications if either of the reactants is in excess?
Thanks a lot!
A resistor has a resistance R, and a battery has an internal resistance r. When the resistor is connected across the battery, ten percent less power is dissipated in R than would be dissipated if the battery had no internal resistance. Show that the ratio r/R is equal to 0.054...
What is the sum of the measures of the interior angles of a convex octagon? What is the sum of the measures of the interior angles of a convex decagon? What is the measure of one interior angle of a regular polygon with 20 sides? Thank You! (:
Isolate x or y in either equation and then subsitute it in to the other equation. x+y=56 x=56-y Subsitute into the other equation: Since x=56-y, the other equation becomes (56-y)+3y=56 56+2y=56 subtract 56 from both sides 2y=0 y=0/2 y=0 then x must be 56
It decreases very very slightly. Mabye from 9.81m/s^2 to 9.80m/s^2, MABYE. Depending on how far you travel away from Earth, the force due to gravity is decreases exponentially. This can be proven with Fg=Gm1m2/r^2 where G=Gravitational constant(6.67*10^-11 N*m^2/kg^2)
Ooo right, my teacher mentioned that, guessed it slipped my mind. Thanks a lot. Diploma tomorrow :(
Log(base a)(a^4*b)-Log(base a)(a*b) is the same as a)4 b)3 c)3a d)a^3 I got the answer as d since subtracting logs with the same base is division. However, the answer key saids its b, Can someone please help me with this?
5 divided by 3, gives you 1.6666666666667 gallons of punch per bowl. In fraction form, it would 5/3 gallons per bowl.
