Answer:
According to this theory, the ocean formed from the escape of water vapor and other gases from the molten rocks of the Earth to the atmosphere surrounding the cooling planet. After the Earth's surface had cooled to a temperature below the boiling point of water, rain began to fall—and continued to fall for centuries.
Explanation:
Answer:
The pressure of a given amount of gas is directly proportional to iys absolute temperature provided that that the volume does not change
Answer:
You need to add 3 100 pound bags of Parkerâs Premium Starter and 5 100 pound bags of Vigoro Ultra Turf fertilizer
Explanation:
You can obtain 3 equations. One for each compound:
For N:
177 pounds = 29x + 18y <em>(1) </em>
<em>-</em><em>Where x are bags of Vigoro Ultra Turf fertilizer</em><em> </em><em>and y are bags of </em>Parkerâs Premium Starte-
For P₂O₅:
134 pounds = 3x + 25y <em>(2)</em>
For K₂O:
42 pounds = 4x + 6y <em>(3)</em>
Replacing (1) in (2):
134 = (531/29 - 54y/29) + 25y
3355/29 = 671y/29
<em>y = 5 bags</em>
Thus,
<em>x = 3 bags</em>
You can replace in each equation to prove that this is the right result.
I hope it helps!
