which elements??? more info please
Answer:
An agricultural drone is an unmanned aerial vehicle used to help optimize agriculture operations, increase crop production, and monitor crop growth. Sensors and digital imaging capabilities can give farmers a richer picture of their fields.
Explanation:
Drones can help farmers to optimize the use of inputs (seed, fertilizers, water), to react more quickly to threats (weeds, pests, fungi), to save time crop scouting (validate treatment/actions taken), to improve variable-rate prescriptions in real time and estimate yield from a field.
Answer:
1 mol of K
Explanation:
The reaction is: 2K + Cl₂ → 2KCl
2 moles of potassium react with 1 mol of chlorine to make the salt, potassium chloride
If you see the stoichiometry from reactants, 2 moles of K need 1 mol of Cl₂ to react, so 1 mol of Cl₂ needs 2 moles of K, to react too.
We can make a rule of three, to reach the answer:
1 mol of Cl₂ needs 2 moles of K to react
Then, 0.5 moles of Cl₂ must react with (0.5 . 2) / 1 = 1 mol of K
