Increasing temperatures in a reaction increases the kinetic energy of the reactant molecules. This causes them to move fast and hence collide with a higher frequency. The higher the rate of collision between the molecules, the faster the reaction.
Answer:
A
Explanation:
A is the answer because it is explaining how wolves are ancestors of dogs
Because the air right above your hot pan of water is so warm, the water vapor can be quickly absorbed there. When the heat is removed, the hot convective up current from the pan vanishes and is replaced with cooler air that can no longer contain as much moisture, which makes the condensing water vapour visible.
First, it's important to discuss the "steam" that is produced by the hot water. While we refer to it as steam, it is not. Water that is heated above 100 degrees Celsius produces steam. The only area in the kitchen where you can see it clearly is if you look very closely at the spout of a boiling kettle. The first 5mm (1/4") of the liquid will be clear when it is boiling very near to the spout.

Ionization energy generally decreases down a group because as one moves down a group, the outermost electron moves <u>further away </u>from the nucleus and it takes <u>less</u> energy to remove it.
Ionization energy, also known as ionization energy, would be the minimal amount of energy needed to free an isolated gaseous atom's or molecule's least loosely bonded electron.
First ionization energy often drops as you advance down a group on the periodic table. This occurs even though the outermost electron would be typically held less securely and can be removed with less energy since it travels farther away from the nucleus.
Therefore, Ionization energy generally decreases down a group because as one moves down a group, the outermost electron moves <u>further away </u>from the nucleus and it takes <u>less</u> energy to remove it.
