That doubling the amoun of A causes the rate to quadruple means that the rate is proportional to the square of the concentration of A, i.e. [A]^2
That doubling the amount of B causes the rate to double means that the rate is proportional to the concentration of B, i.e. [B]
Then, rate = k[A]^2 [B], which is the first option.
Answer:- 2.39 mL are required.
Solution:- It's a dilution problem and to solve this type of problems we use the dilution equation:
Where, and are molarities of concentrated and diluted solutions and and are their respective volumes.
= 1.10M
= 5.00mM = 0.005M (since, mM stands for milli molar and M stands for molar. 1M = 1000mM)
= ?
= 525 mL
Let's plug in the given values in the formula:
So, 2.39 mL of 1.10M are needed to make 525 mL of 5.00mM solution.
Answer:
1 mole
Explanation:
Data obtained from the question include:
P (pressure) = 750 torr
But 760torr = 1atm
750 torr = 750/760 = 0.99atm
V (volume) = 25L
T (temperature) = 300K
R (gas constant) = 0.082atm.L/Kmol
n (number of mole) =?
Using the ideal gas equation PV = nRT, we can easily find the number of mole as illustrated below:
PV = nRT
n = PV /RT
n = 0.99 x 25 / 0.082 x 300k
n = 1 mole
Therefore, the number of mole of the gas is 1 mole
Answer:
the wrong statement is
d) the order of conductivity for different states is gas > liquid > solid
Explanation:
- the correct order is solid > liquid > gas
the thermal conductivity is a property of materials that it values the ability to transmit heat through them. In general, for metals and solid of continuos bodies the conductivity is high.
k = q / ΔT
∴ q: heat flux
∴ ΔT; temperature gradient
When a material undergoes changes of states, the thermal conductivity can change. for example, the conductivity of frozen water (a 0°C) is higer than that of liquid water.....from literature.

Textiles for clothes are also sometimes finished with chemicals, for example, to stiffen them and make them wrinkle-free. Chemicals in their nanoforms are helping make textiles more resistant to water, stains, wrinkles, bacteria and mould. Some of the chemicals can be harmful.
