Answer:
Explanation:
solar energy
Heat from the sun, or solar energy, powers the evaporation process. It soaks up moisture from soil in a garden, as well as the biggest oceans and lakes. The water level will decrease as it is exposed to the heat of the sun.
Hydrogen reacts with oxygen to form water based on the following equation:
2H2 + O2 ..............> 2H2O
This means that 4 grams of hydrogen are required to react with 32 grams of oxygen to release 36 grams of water.
We need to calculate how munch oxygen is needed to react with 4.8 grams of hydrogen. We can do this using cross multiplication as follows:
amount of oxygen = (4.8x32) / 4 = 38.4 grams
This means that we have no limiting reagent here and both reactants will completely react.
We know that 4 grams of hydrogen are required to produce 36 grams of water. Therefore:
amount of water produced from 4.8 grams of hydrogen = (4.8 x 36) /4 = 43.2 grams
Answer:
Because Polar regions get less of the sun's direct rays, they are the coldest climates on Earth.
