Jake collected samples of two substances while he was out walking. after taking the samples home, he ran tests and found that one substance is slippery and conducts electricity in water. these properties made jake conclude that the substance is probably . the other substance continuously made bubbles of hydrogen gas when jake dropped magnesium into an aqueous solution of the substance. jake concluded that the second substance is probably .

One substance which is slippery and conducts electricity in water is probably a base. The other substance which continuously made bubbles of hydrogen gas when Jake dropped magnesium into an aqueous solution of the substance is probably a acid.

Explanation: Bases are those substances which donates ions when dissolved in water. Thus bases produce ions which help in the conduction of electric current.

Bases are slippery in nature and are used in manufacturing of soaps.

Acids are those substances which donates ions when dissolved in water. Thus acids also produce ions which help in the conduction of electric current. Acids are not slippery in nature.

Thus magnesium when dropped into an aqueous solution of the acid releases hydrogen gas.

the law of conservation of mass states that in a chemical reaction, the total mass of reactants is equal to the total mass of products. because atoms are only rearranged in a chemical reaction, there must be the same number of sodium atoms and chlorine atoms in both the reactants and products

answer

fusion: the energy source of stars. the energy released from the collapse of the gas into a protostar causes the center of the protostar to become extremely hot. when the core is hot enough, nuclear fusion commences. fusion is the process where two hydrogen atoms combine to form a helium atom, releasing energy.
