Answer:
Increasing the temperature will cause chemical changes to occur faster. Decreasing the temperature, causes the particles to lose energy which causes them to move around less and slower. The less they move, the less collisions occur, and the less reactions occur between the chemicals = slower reaction rate.
Explanation:
Answer:
The metal is most likely Sodium.
Explanation:
Iron is not soft enough to be cut with a knife and will not react violently with water. When Iron reacts with water it just slowly rusts.
Copper is somewhat malleable, however, does not really react with water and only forms an oxide layer in the air.
Sodium is soft enough to be cut with a knife (I know this because I have worked with it and seen people work with it). It is also an alkali metal which are known to explode when in water.
Gold is malleable but does not really react with anything and is considered inert.
Answer:
H₂ + Cl₂ → 2HCl
Explanation:
The equation that is balanced and follows the law of conservation of mass is:
H₂ + Cl₂ → 2HCl
Based on the law of conservation of mass "in a chemical reaction, matter is neither created nor destroyed but they combine with one another".
It suggests that the number of species on both sides of the expression must be the same.
For the given reaction:
H₂ + Cl₂ → 2HCl
Reactant side Product side
H 2 2
Cl 2 2
<span>Gold is actually very soft. If rings were made of pure gold they would bend and become disfigured. Other elements are added to give the ring its stability.</span>
