The salt 
is the least soluble salt at 50
.
Answer: Option 1
<u>Explanation:
</u>
As it is clear that , a gas so the solubility of it decreases on increasing the temperature of water. Because gas molecule starts to evaporate on attaining heat with the increase of temperature thus leading to reduction in the solubility of them.
As most of the gas molecules get vaporised the solubility in water gradually decreases for this compound. It is also clear from the solubility graphs of the various salts.
Answer:
This is a chemical property. If iron does rust, this is a slow chemical change since rust is an iron oxide with different properties than iron metal.
The correct answer for the question that is being presented above is this one: "a. the wavelength of light emitted by the star." The mass of a star can be determined by studying <span>the wavelength of light emitted by the star. It also has something to do with the gravitational force that it exerts.</span>
Answer:
We use X-rays to help the injured, Radiowaves to communicate or entertain, and Visible light to see.
Answer:
Potential Energy
Explanation:
Potential energy is the energy stored in an object due to it's position relative to some zero position. An object possesses gravitational potential energy if it is positioned at a height above (or below) the zero height.
