To balance the equation, Hydrogen ion should be added to the left of the equation and water to the right of the equation as follows:
Balancing the equation
It can be noted that: ions are balanced at 18+ on left hand side and 18+ on right and side just like all the other chemical elements.
Answer:
organic chemistry
Explanation:
There are many branches of chemistry. Some of them are physical chemistry, analytical chemistry, inorganic chemistry and organic chemistry.
A chemist is testing the quality of a wine produced by a vineyard. It means he will test the structure, properties, and preparation of wine. All these tests comes under organic chemistry.
Hence, the correct option is (d) "organic chemistry"
Answer:
a. 300 Kg of fertilizer
b. 225 Kg of fertilizer
c. 400 Kg of fertilizer
d. 600 Kg of fertilizer
Explanation:
The percentage composition ratio of Nitrogen, Phosphorus and Potassium in a 1 Kg bag of the given fertilizer is 40:15:10.
Therefore a 1 Kg bag contains;
40/100 * 1 Kg = 0.4 Kg of Nitrogen;
15/100 * 1 Kg = 0.15 Kg of phosphorus;
10/100 * 1 Kg = 0.1 Kg of potassium
Quantity of fertilizer required to add to a hectare to supply;
a. Nitrogen at 120 kg/ha = 120/0.4 = 300 Kg of fertilizer
b.. Nitrogen at 90 Kg/ha = 90/0.4 = 225 Kg of fertilizer
c. Phosphorus at a rate of 60 kg/ha = 60/0.15 = 400 Kg of fertilizer
d. Potassium at a rate of 60 kg/ha = 60/0.1 = 600 Kg of fertilizer
