Answer:
Explanation:
Sodium acetate is a hygroscopic powder very soluble in water. Sodium acetate is a solution which contains a greater amount of dissolved substance.
4Na + 4H20 -> 4NaOH + 2H2
waters coefficient is 4.
Answer: Conduction
Explanation:
Conduction means the process by which heat or electricity is directly transmitted through a substance when there is a difference of temperature or of electrical potential between adjoining regions, without movement of the material.
Meaning that its when an object touches another object and heat gets transferred.
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.
