snow mold occurs in round patches of grass in the lawn. The patches contain a fussy substance (the mold), that appears in grey or pink; the most dangerous of the two. Mold is formed whenever a lot of snow is left on the lawn for a long period of time, this causes the mold to grow underneath. Late fertilization with a lot of nitrogen promotes mold. Dead grass or thatch can cause mold to develop. Gently raking allows airflow into the grass and promotes new grass growth. The putting down of gras...

In this video, we learn how to properly balance chemical equations. You will see what substances are in each side of the equation. You will then need to count the atoms that are on each side of the chemical equation. Once you write down the number of atoms on each side, you will need to even them out. To do this, you need to change the coefficients within the equation. These change the total number of atoms inside of a chemical. Once you do this, you will add more to each atom present and the...
