They give a double displacement reaction where the ions switch places and give sodium nitrate (NaNO3) and silver chloride (AgCl) as the products. Silver nitrate is also very soluble in water, but silver chloride is highly insoluble in water and will precipitate out of solution as a white solid.
Explanation:
It is given that peak (maximum) emission of star is 300 nm.
And, it is known that according to Wein's displacement relation between wavelength and temperature is as follows.
= 2898 micrometer.K
Hence, putting the given values into the above formula as follows.
= 2898 micrometer.K
= 2898 \times 10^{-6} meter.K
T = K
= 9660 K
Thus, we can conclude that the estimated surface temperature of star is 9660 K.
Answer:
In the other of increasing wavelength we arrange as
<em>X-rays</em>
<em>ultraviolet</em>
<em>green light</em>
<em>red light</em>
<em>infrared</em>
<em>radio waves</em>
<em></em>
Explanation:
In the electromagnetic spectrum, wavelength decreases with increase in the energy of the electromagnetic wave. Since the e-m wave spectrum is arranged in the order of increasing energy (decreasing wavelength) as: Radio wave; infrared; visible light; ultraviolet; x-rays; gamma rays. Within the visible light, the green light has more energy than the red light. Therefore, the arrangement should be in the reverse direction of their increasing energy.
Answer: 5. Positive
6. Negative
9. Oxygen carbon hydrogen nitrogen
Explanation:
Answer:Animal cells are eukaryotic cells that have both a membrane-bound nucleus and other membrane-bound organelles.
Explanation:Animal cells are eukaryotic cells that have both a membrane-bound nucleus and other membrane-bound organelles. These organelles carry out specific functions that are needed for the normal functioning of the cell. Plant and animal cells are similar in that they are both eukaryotic and have similar types of organelles
