Answer:
30100000000000000000 atoms
Explanation:
Ar of Fe : 56
0.028/56 = 0.0005 moles of Fe
0.0005 * 6.02 * 10^23(Avagardro's law of constant)
= 3.01*10^20 atoms
That is called the<u> variable</u> because it varies/changes in the experiment,
it's like x in algebra (with more than one placeholder), if it changes, it normally gives you a different result
The correct answer that would best complete the given statement above would be option 2. <span>The relationship between molecular velocities and temperature is a direct relationship. In other words, their relationship is directly proportional. Hope that this is the answer that you are looking for. </span>
Answer:
Aluminum
Explanation:
Given
<em>See attachment for chart</em>
Required
Identify the unknown substance
To do this, we simply calculate the specific heat capacity from the given parameters using:
This gives:
So, we have:
From the attached chart, we have:
--- The specific heat capacity of Aluminum
<em>Hence, the unknown substance is Aluminum</em>
