Irrigation is the artificial process of applying controlled amounts of water to land to assist in production of crops. Irrigation helps to grow agricultural crops, maintain landscapes, and revegetate disturbed soils in dry areas and during periods of less than average rainfall.
There are 60 seconds in one minute
565900 / 60 = 9431.667 minutes in 565,900 seconds
There are 60 minutes in an hour
9431.667 minutes / 60 = 157.9144 hours in 565900 seconds
There are 24 hours in 1 day
157.9144 hours / 24 hours = 6.5498 days.
Answer:
Yes.
General Formulas and Concepts:
<u>Chemistry - Stoichiometry</u>
- Balancing reactions
- Reaction prediction
Explanation:
<u>Step 1: RxN</u>
Zn + HCl → ZnCl₂ + H₂
<u>Step 2: Balance RxN</u>
Zn + 2HCl → ZnCl₂ + H₂
- Need 2 H's on both sides
- Need equal amount of Cl's on both sides
The correct answer is 2.99 helium atoms.
I hoped this helped!
