Start with three carbons bound together (-c-c-c-). What individual atoms or functional groups could you add to the carbons to make the molecule hydrophobic?
A solution is prepared by mixing 0.3355 mol of NaNO3 (84.995 g mol-1) with 235.0 g of water (18.015 g mol-1). Its density is 1.0733 g mL-1. What is the molality of the solution?
Give a nanoscale interpretation of the fact that at the melting point the density of solid mercury is greater than the density of liquid mercury, and at the boiling point the density of liquid mercury is great than the density of gaseous mercury.
Write a net Ionic equation for the reaction that takes place when aq barium chloride soln reacts with an aq soln of potassium phosphate.
In solid nickel the atoms are so tightly packed they touch each other. Using geometry and the equation 4r = a(2)1/2 and a = 3.524 calculate the value for r, the radius of a nickel atom. a. 2.27 b. 1.24 c. 3.9 d. 0.92 e. 4.7
Assume a temperature of 298 K and 1 M concentration. By what factor is one reaction faster than the other?
A solution is made with 100mL of DI water and 8mL of .10 HCL (hydrochloric acid). then 2.50mL of NaOH is added. What is the new pH?
Assume that you started with only 1.80 g of sodium benzoate. Assuming that the reaction proceeds to form benzoic acid, what would your theoretical yield be? use two decimal places
The rate constant for electron transfer between V 2+ (aq) and V 3+ (aq) is observed to depend on [H+]: k = a + b/[H+], where a and b are constants. Propose a mechanism and express a and b in terms of the rate constants in your mechanism.
1) the symbols for the elements in the compound. 2) the oxidation numbers of the elements involved and write them as superscripts to the right of the elemental symbols
A solution contains 9.87 (g) of dissolved silver. How many moles of potassium chloride must be added to the solution to completely precipitate all of the silver?
If we too EXACTLY 1.00mL of a 1.000 M solution of Cu(NO3)2 and placed it in 99.000 Ml of water and mixed it, then took 2.00 mL of this solution and plced it in 18.000 mL of water, A) what is the concentration (in mole/L or M) of Cu2+ and NO3 in th..
