Why doesnt iron burst into flames when it rusts

Chemistry

Katarina [22]3 years ago

Rust does not have the properties to catch onto flames. However, if you light it on fire, then it would probably catch in flames but not instantly and will not continue to burn unless you have soaked it in oil or flammable object or substance. :) Hope this helps!

Georgia [21]

The Probability of spending at least half an hour on exactly one subject is mathematically given as

P(1)= 0.50

<h3>What is the Probability of spending at least half an hour on exactly one  subject </h3>

Question Parameters:

The amount of study time that Actuary Tong will spend on each exam in a day follows a continuous random variable that ranges from 0 to 1 hour.

Generally, the equation for the Probability of spending at least half an hour on a subject is mathematically given as

P(A)= (1 – 0.5)/(1 – 0)

P(A)= 0.5

Hence, the Probability of spending at least half an hour on exactly one subject is mathematically given as

P(1)=2​​​​​​C1 * 0.5 * 0.5

P(1)= 0.50

Given 200ul of a 0.5mg/ml stock solution of BSA, how much do you pipet into a test tube so that you are adding 5ug of BSA to the
Trava [24]

<u>Answer: </u>10\mu L of volume needs to be pipetted out in the test tube.

<u>Explanation:</u>

We are given:

Mass of BSA to be formed = 5\mu g=0.005mg      (Conversion factor: 1mg=1000\mu g

Volume of stock solution = 200\mu L=0.2mL    (Conversion factor: 1mL=1000\mu L

It is also given that for the mass of BSA is 0.5 g, the volume used up is 1 mL

In order to have, 0.005 g, the volume of stock solution needed will be = \frac{1mL}{0.5g}\times 0.005g=0.01mL=10\mu L

Hence, 10\mu L of volume needs to be pipetted out in the test tube.
