Answer:
c is correct option
according to the question.
Answer: star
Exoplanets are the planets present in the other star system. There are billions of stars in our galaxy and we expect presence of other planetary systems similar to our solar system. Exoplanets can be detected by a) radial velocity method b) astrometric method c) transient method. In the radial method, we observe the changes in the spectrum of the light coming from star when an exoplanet is orbiting it. There is change in gravitational pull as the planets goes around the star. It sometimes pulls into smaller orbit. like this the star wobbles back and forth. By measuring the blueshift and redshift in the star's spectrum, exoplanet can be discovered.
Answer:
182.3 g
Explanation:
number of mols of HCl = 5 mols
molecular weight of HCl = 36.46 g/mol
m = mass of HCl = number of mols x molecular weight
m = 5 mols * 36.46 g/mol
m = 182.3 g
<span>Endothermic Reaction. This reaction or process absorbs energy from its surroundings, mostly, but will not always be, in form of heat. A reaction that requires the input of energy that breaks a bond will always be endothermic. Best examples of endothermic reaction are: 1) melting cubes; 2) evaporating of liquid; 3) melting solid salts, etc.</span>
