Create your conversion factors.
You know that 1 micrometer = 1/1000000 m
Then,
[1 micrometer]^2 =[1/1000000 m]^2 =>
=> 1 = [1000000]^2 micrometer^2 / m^2
Now multiply the given area times your conversion factor:
1.50 (micrometer)^2 * [1/1000000]^2 micrometer^2 / m^2 = 1.50*10^(-12) m^2
Answer: 1.50*10^(-12) m^2
Quantitative is the amount of something. Qualitative is the degree of excellence of something.
Answer:
Chemical properties can change due to a variety of things. If you were to talk about Weathering, the chemical properties change when there is acid rain, water, CO2, and O2. Chemical Properties change when the chemical properties of an object change too.
B. it determines how difficult it is to start the reaction
2 ICl + H2 ----> I2 + 2 HCl
as given that rate is first order with respect to ICl and second order with respect to H2
The rate law will be
Rate = K [ICl] [ H2]^2
b) Given that K = 2.01 M^-2 s^-1
Concentrations are
[ICl] = 0.273 m and [H2] = 0.217 m
Therefore rate = 2.01 X (0.273)(0.217)^2 = 0.0258 M / s
