Answer: the answer is B
Explanation: i go to connexus i had this question
Answer:
yes....
Explanation:
Let me explain the molecular orbital diagram of N2 using its diagram.
one atom of nitrogen has 7 electrons so a N2 molecule will have 14 electrons
so first 2 electrons go in 1s sigma bond
next 2 in 1s sigma anti bond orbital
next 2 in 2s sigma bond orbital
next 2 in 2s sigma anti bond orbital
next 2 in 2pz sigma bond( assuming that z axis is the internuclear axis ) orbital
Answer:
36% m/v
Explanation:
An antibiotic solution must be prepared by diluting 100. mL of a 90. % m/v solution and bringing up the volume to 250 mL. What is the concentration of the resulting solution?
the new solution is 100/250 X 90% m/v = 36% m/v
Answer:
1. Chemical reactions
2.Substances
3. Properties
4. Precipitate
5. Light
6. Temperature
7. Color
8. Gas
Explanation:
During chemical reactions, new substances that possess new properties are formed. During the process of chemical reactions, evidences are found. Some of the evidences are formation of precipitate or light gel, production of gases and changes in colour and temperature.
Chemical reactions start with the substances or compounds which are known as reactants. The reactants react to form new substances known as the products which possess new properties.
Answer:
C. 1:30
Explanation:
The toy car is .5 feet long and the actual car is 15 feet long
This gives you a ratio of
.5:15
Now for everything you have to remember this
.5:15
=1:30
=2:45
=3:60
C is the only answer that matches any of the ratios above.
Even if you went farther in the ratios none of them would match this ratio.
Hope this helped.
