Covalent compounds are compounds that share electrons. They tend to have properties like lower melting points and lower conductivity.
Problem 2
You start out with 216 ugrams of Fermium - 253. After 3 days, you will have 1/2 as much. 108 ugrams is what you have.
Another 3 days goes by. You started with 108 ugrams. That gets cut in 1/2 again. Now you have 54 ugrams.
Finally another 3 days goes by. You started with 54 ugrams. you now have 1/2 as much which would be 27 ugrams
#days Amount in micrograms
0 216
3 108
6 54
9 27
Problem One
You are using Nitrogen as your base example. The first thing you should do is fill in the table. Then you should try and make some rules. You need the rules in case the exam you are preparing for picks a different element to talk about these bond tendencies. In any event, it's handy to think this way.
<em><u>Table</u></em>
Bond Energy Kj/Mol Bond Length pico meters
N - N 167 145
N=N 418 125
N≡N 942 110
<em><u>Rules</u></em>
As the number of bonds INCREASES, the energy contained in the bond goes UP
As the number of bonds INCREASES, the length of the bond goes DOWN.
Answer:
O2 and O3 are allotropes of Oxygen, therefore they have (4) different chemical and physical properties.
Explanation:
Answer:
correct option: 1
Explanation:
As given in the question that gas are taken from one sate to another state through different paths and asking which quantity will always remains same.
1. internal energy of gas is not path dependent so internal energy will remains same it depend only on the initial and final point .
2. Heat and work are path dependent means its matter the gas is taken by which path. so option 2 and 3 are wrong.
