Answer:
b. 295 pm
Explanation:
To answer this question we need to use the equation of a face-centered cubic laticce:
Edge length = √8 R
<em>Where R is radius of the atom.</em>
<em />
Replacing:
417pm = √8 R
R = 147.4pm is the radius of the atom
As diameter = 2 radius.
Diameter of the metal atom is:
147.4pm* 2 =
295pm
Right answer is:
<h3>b. 295 pm
</h3>
It will have metal in it . The other would not. It’s actually very simple
Answer:2-methylpropane
Explanation:
The structure of 2-methylpropane is contrasted with that of propane in the image attached. It is easy to see that 2-methylpropane contains a tertiary carbon atom which forms a stable radical. This stable radical formed will eventually lead to the yield of a single product which is 2-chloro-2-methylpropane. A tertiary radical is the most stable radical and often leads to the formation of a single product.
The answer to the question is D
<h2>The required option d) "specific heat" is correct.</h2>
Explanation:
- To raise the temperature of any substance or material of certain mass to respective temperature it requires some amount of heat.
- Specific heat is the amount of heat necessary to raise the temperature of the substance of 1 gram to 1 Kelvin.
- It is the amount of heat which is required to raise the temperature per unit mass to per unit temperature.
- Thus, the required "option d) specific heat" is correct.
