Answer:
The fox who shed their heavy coat in the summer.
Explanation:
If a fox has the ability to shed its coat in the summer, it will have no difficulties adapting to new temperatures even during winter. However, the heavy-coated one will.
Here we have to calculate the number of moles of valuable propane can be prepared from 1.8 moles of carbon.
From 1.8 moles of carbon 0.3 moles of propane can be prepared by the reaction.
From 6 moles of carbon (C) 1 moles of valuable propane (C₃H₈) can be prepared.
Thus from 1.8 moles of C we can obtain
×1.8 = 0.3 moles of the propane can be prepared.
Thus the amount of propane produced in this reaction is determined.
Answer:
There are 1.253*10²⁴ particles in 2.080 moles
Explanation:
Avogadro's number is called the number of particles that make up a substance (usually atoms or molecules) that can be found in the amount of one mole. In other words, Avogadro's number is the number of molecules that one mole of any substance contains. Its value is 6.023 * 10²³ particles per mole.
So, you can apply a rule of three as follows: if 1 mole has 6.023*10²³ particles, then 2.080 moles, how many particles does it have?
![amount of particles=\frac{2.080 moles*6.023*10^{23}particles }{1 mole}](https://tex.z-dn.net/?f=amount%20of%20particles%3D%5Cfrac%7B2.080%20moles%2A6.023%2A10%5E%7B23%7Dparticles%20%7D%7B1%20mole%7D)
amount of particles= 1.253*10²⁴ particles
<u><em>There are 1.253*10²⁴ particles in 2.080 moles</em></u>
Answer:
See below.
Explanation:
I'll do the second row for you the other 2 are done in exactly te same way.
B. Area of 1 side of cube = 2*2 = 4.
Surface area = 4*6 = 24
Volume = 2*2*2 = 8.
Surface area / volume = 24/8 = 3.
Ratio of Suface Area to Volume = 24 : 8 = 3 : 1. (divide both by 8)
