Explanation:
No of molecules=0.500×6.023×10²³=3.011×10²³ molecules
Temperature can change a reaction rate because adding or taking away heat means energy is being added or taken away. When energy is added, the particles speed up, so there is a greater chance of the reactants colliding to form the products, which increases the reaction rate. When energy is taken away, the particles more slower, so they don't collide as easily, which slows down the reaction rate.
Therefore, the answer is D.
Magnesium is the correct answer
Answer:
C
Explanation:
This is because matter is anything that has mass and occupies space.Therefore the space occupied by matter is volume
