Even though the radishes watered with a 5.6 pH grew the best, they did not turn out to be the healthiest. The 7 pH radishes grew the most thick and sturdy. In conclusion, radishes watered with a low pH level do not grow to be tall and radishes watered with an exact acid level to neutral grow to be tall.

Explanation:
A set that contain no element is called the EMPTY OR NULL SET and it is represented by { }. A set is defined as a well defined collection of objects. Elements of a set are those objects that belong to a set. So, an empty set do not have any object inside of it.
Answer:
0.2934 g of N₂
Explanation:
The balance chemical equation for given reaction is as follow;
2 NH₃ + 3 CuO → 3 Cu + N₂ + 3 H₂O
Step 1: <u>Calculate Moles of CuO as;</u>
Moles = Mass / M.Mass
Moles = 2.5 g / 79.54 g/mol
Moles = 0.0314 moles of CuO
Step 2: <u>Find out moles of N₂ as;</u>
According to equation,
3 moles of CuO produced = 1 mole of N₂
So,
0.0314 moles of CuO will produce = X moles of N₂
Solving for X,
X = 0.0314 mol × 1 mol / 3 mol
X = 0.0104 moles of N₂
Step 3: <u>Calculate Mass of N₂ as;</u>
Mass = Moles × M.Mass
Mass = 0.0104 mol × 28.01 g/mol
Mass = 0.2934 g of N₂
