Consider a frictionless track as shown in the figure below. A block of mass m1 = 5.60 kg is released from A. It makes a head-on elastic collision at B with a block of mass m2 = 11.0 kg that is initially at rest. Calculate the maximum height to which m1 rises after the collision.

here is the picture:

what is the IUPAC for this and

Given that the halogens have the same degree of bulkiness, which conformer has the most stability (could be both)

How many σ bonds are there in this hydrocarbon?

http://www.webassign.net/ksorgchem2/02-P-012a.jpg

it says both 6 and 22 are wrong

what is the net Brønsted equation for the following substance. (for polyprotic acids, only show one proton transfer. also, do not include spectator ions)

native lime (calcium oxide) with a pH of 10.50

i tried CaO + H2O --> Ca^2+ + 2OH^- and it said a part in the products is wrong

Which of the acids below will have the lowest pH in a 0.010 M solution of the acid? (Hint: Larger Ka values favor products and smaller Ka values favor reactants.)

1) HCO3^1-

2) HNO2

3) HClO

4) HSO4^1-

Suppose Ca(OH)2 were used as the titrant, instead of NaOH. This will make the titrant twice as concentrated in hydroxide ion. The analyte will still be HC2H3O2.

What is the stoichiometric ratio of HC2H3O2 to Ca(OH)2?

What's the dissolution reaction for the ionic solids below?

AlPO4

KBr

KClO4

complete the following sentances:

The (larger/smaller) the Ksp value, the more product that is formed at equilibrium.

The lower the charges on the ions in an ionic solid, the more (insoluble/soluble) the solid is.
