Answer:
The density of the liquid is 4.9 g/ml
Explanation:
Density of a liquid is usually measured by filling a beaker of known weight and known capacity (total volume in ml you can fill it) and weighing it. The difference between the total weight (beaker+liquid) and the beaker weight is the liquid weight. Finally, you must divide <em>liquid weight/volume</em> to obtain density.
For the problem:
beaker=15 g
beaker+liquid=64 g
⇒liquid= 64 g - 15 g = 49 g
density= 
= 
= 4.9 g/ml
Answer:
[OH-]= 1.995×10^-11M
Explanation:
pOH= 14- pH = 14-3.3 =10.7
pOH= -log[OH-]
[OH-]=antilog (-10.7)
[OH-]= 1.995×10^-11M
Rate = 3.37x10-3 M^-1 min-1 [A]^2 and the initial concentration of a is 0.122M.
A rate law indicates the rate of a chemical response depends on reactant concentration. For a response inclusive of the price regulation commonly has the form rate = ok[A]ⁿ, in which okay is a proportionality constant known as the fee regular and n is the order.
The charge of a chemical response is, perhaps, its maximum crucial asset because it dictates whether or not a reaction can arise all throughout an entire life. knowing the charge regulation, an expression concerning the price to the concentrations of reactants can assist a chemist to modify the response conditions to get an extra suitable rate.
half-life is the time taken for the radioactivity of a substance to fall to 1/2 its authentic cost whereas implies existence is the common life of all the nuclei of a particular risky atomic species.
