How do yo calculate a number to the power of 2.08 i.e. not a whole number. so 4 to the power of 2.08 Thanks.
The mole fraction of an aqueous solution of magnesium chlorate is 0.371. Calculate the molarity (in mol/L) of the magnesium chlorate solution, if the density of the solution is 1.39 g mL-1.
calculate the pH of 20.00mL of 2.00 M HCl diluted to 0.500 L
The equilibrium constant for the reaction: 2NO(g)+Br2(g)<==>2NOBr(g) Kc=1.3x10^-2 at 1000 Kelvin Calculate Kc for: NOBr(g)<==>NO(g)+ 1/2Br2(g)
Calculate the [OH-] for a solution in which [H+] is 1000 times greater than [OH-]? and will the final result be acidic, basic, or neutral?
assuming complete dissociation of the solute, how many grams of KNO3 must be added to 275 mL of water to produce a solution that freezes at -14.5 C? The freezing point for pure water is 0.0 C and is equal to 1.86 C/m .
m1= mass of the bullet m2= mass of the block Vf=sqrt(2gh) v1= initial velocity of bullet v2= initial velocity of the block = 0 so first is conservation of momentum m1v1+m2v2=(m1+v2)Vf solve for v1 (note m2v2=0) v1=((m1+m2)/m2)/Vf to find Vf look at conservation of energy KE+PE...
In the following experiment, a coffee-cup calorimeter containing 100 mL of H20 is used. The initial temperature of the calorimeter is 23.0 C . If 3.60 g of CaCl2is added to the calorimeter, what will be the final temperature of the solution in the calorimeter? The heat of the ...
