Answer:

4 * 10^{-5}cm = 0.00004cm

Explanation:

Given

4 * 10^{-5}cm = [\ ]cm

Required

Solve

Apply law of indices

4 * \frac{1}{10^5}cm = [\ ]cm

Evaluate 10^5

4 * \frac{1}{100000}cm = [\ ]cm

4 * 0.00001cm = [\ ]cm

0.00004cm = [\ ]cm

Hence:

4 * 10^{-5}cm = 0.00004cm

Calculate the number of molecules in a deep breath of air whose volume is 2.15 L at body temperature, 37 ∘C, and a pressure of 7
Zinaida [17]
PV = nRT 
R = 0.0821 L * atm / mol * K 
(ideal gas constant) 

First, convert 735 torr to atm. Divide by 760. 
(1 atm = 760 torr) 

735 torr * 1 atm / 760 torr = 0.967 atm 
Then, convert 37 C to Kelvin. Just add 273. 
37 C = 310K 

n = PV / RT 
= (0.967)(2.07) / (0.0821)(310) 
= 0.0786 mol 

<span>0.0786 mol * 6.02 * 10^23 molecules / 1 mol = 4.73 * 10^22 molecules </span>

Ludmilka [50]

Answer:

The answer is: Applied Chemistry

Explanation:

Apllied Chemistry is a branch of Chemistry that deals with the application and use of Chemistry principles and theories to answer a specific question or solve real world problems. It is aimed at taking Chemistry knowlege from the classroom to the real world. In this example, Marie noticed that a problem had arisen, and that is corrosion of metals, and she set out to apply the principles of Chemistry to make a paint formulation that prevvents corrosion, not just on paper with a bunch of formulas and calculations, but translated into a real life substance. On the other hand, pure Chemistry is the theoretical aspect of Chemistry, where the result of the researches are purely for knowlege and not for real world application.
