Answer:

D. Catalysts speed up the rate of reactions by lowering the amount of energy required for the reaction to proceed.

Explanation:

A catalyst is a substance that:

  • speeds up the rate of a reaction .
  • does not alter the products of the reaction .
  • is unchanged chemically and in mass at the end of the reaction.

<em>A catalyst provides an alternative reaction pathway that has a lower activation energy than the uncatalyzed reaction. </em>

<em></em>

The figure shows how the energy of the reactants and products change during a reaction.

1s22s22p63s23p3<br> what element does this represent
s344n2d4d5 [400]

Answer:

Its phosphorus (P)

Explanation:

In writing the electron configuration for Phosphorus the first two electrons will go in the 1s orbital. Since 1s can only hold two electrons the next 2 electrons for Phosphorous go in the 2s orbital. The next six electrons will go in the 2p orbital. The p orbital can hold up to six electrons. We'll put six in the 2p orbital and then put the next two electrons in the 3s. Since the 3s if now full we'll move to the 3p where we'll place the remaining three electrons. Therefore the Phosphorus electron configuration will be 1s22s22p63s23p3.
