Barium nitrate and methane (CH4) are both soluble. They both will dissolve in water, however, barium nitrate will dissociate becoming barium 2+ ions and nitrate becoming NO3 1- ions. All nitrates are soluble and dissociate. CH4 is a weak base and does dissolves but doesn't dissociate. So in solubility terms.... they are both equally soluble just one happens to dissociate into its cations and anions. Hope this helps!
Answer:
C-Electrical energy changed into mechanical energy
Explanation:
Energy, according to the law of conservation of energy, is said to neither be created or lost but only interchangeable from one form to another. Energy exists in different forms. The process by which one form of energy changes to another is called TRANSFORMATION of energy.
However, certain household appliances or devices bring about this transformation of energy. For example, in a case where Tony turns a fan on when his room becomes uncomfortably hot. The fan uses an electric source to get powered on, which then facilitates the blades of the fan to move fast in order to bring about a cool atmosphere.
The fan converts ELECTRICAL energy (electric source) into MECHANICAL energy (moving energy).

Answer: Gas , Solid and Liquid
Explanation:
To complete each sentence , One can easily conclude that the various state of matter are in question here.
To further explain better,
(1) Gas molecule is consider to b moving and also move at a faster rate is respect to others.
(2)Solid molecule usual takes a standing still position unless an external pressure acts on it.
(3) Liquid molecule is capable of starting at same location and then move to another location but not at a faster rate compare to gas molecule.
