In three different experiments, the following results were obtained for the reaction
a -> products:
[a]o = 1.00m, t1/2=50 min ;
[a]o = 2.00m, t1/2 = 25 min;
[a]o = 0.50m, t1/2 = 100 min.

write the rate equation for this reaction, and indicate the value of k?

Asolution contains 225 g of sodium chloride, nacl, dissolved in enough water to make a 0.25 l of solution. what is the molarity of the solution?

Which samples do the atoms have the least kinetic energy

An engineer decides to use a slightly weaker material rather than a stronger material, since she knows that the stronger material can break suddenly. this is an example of what? a choosing a material that will show warning before it fails b using composite materials that combine strength c using a material for multiple applications d using design techniques that increase efficiency and reduce cost
