Answer:
By observing the color of lines in the spectrum.
Explanation:
There are two types of lines in the spectrum explained below:
i) Bright lines: Bright lines occurs on the spectrum when atoms emit photons. These bright lines show the emission line spectrum.
ii) Dark Lines: Dark lines occurs on the spectrum when atoms absorb photons. These black lines show the absorption line spectrum.
Hence, by observing the color of lines it is possible to identify emission line spectrum and absorption line spectrum.
Answer:
It has only 1 electron in its valence shell and if that electron is removed it will acquire noble gas configuration
Explanation:
Sodium forms an ion of charge +1 as in its ionic state it has inert gas configuration
It forms an ion of charge +1 when the valence shell electron is removed to gain the noble gas configuration and the electrons can be removed mostly from its valence shell because inner shell electrons will be tightly bounded to the nucleus of the atom and it requires high energy to remove the electron present in the inner shell when compared to the valence shell (outermost shell)
Answer:
The correct answer is no.
Explanation:
The temperature of a person changes depending on their age, the physical activity they are doing and until the time of day.
There is an established average temperature that is 98.6 ° F (37 ° C) as a healthy temperature.
If the temperature exceeds 100.4 ° F (38 ° C) it means that you may be ill or have an infection.
The difference in temperature by age is very minimal, but it is still a difference. Let's see:
- Babies and children: from 97.9 ° F (36.6 ° C) to 99 ° F (37.2 ° C).
- Adults: from 97 ° F (36.1 ° C) to 99 ° F (37.2 ° C).
- Adults over age 65: 98.6 ° F (36.2 ° C).
I<span>f you have studied enzymes its a similar concept. Cells have proteins on the surface of their cell which hormones bind to (called receptors) The receptor must be a complimentary shape to the hormone for it to bind. Only target cells have the receptor with the complimentary shape so only these cells will be affected.</span>
Answer:
Sonia will experience repulsion in two balloons
Explanation:
Here when we rub the balloon with the woolen cloth then due to friction between the cloth and balloon electrons from balloon will transfer to woolen cloth.
Due to transfer of electron the balloon will get positive charge which is given by
so here since both balloons are rubbed against woolen cloth so both balloon will get some positive charge
now we know by the property of charge that two similar charges will always repel each other so here two balloons will repel each other after they rubbed against woolen cloth.
