Commercial agriculture can often lead to water-quality problems in the following ways:
- The washing of fertilizers and pesticides into water bodies from farms.
<h3>What is water quality?</h3>
Water quality refers to the state of a water body that encompasses it's physical, chemical and biological characteristics.
The water quality of a water body is crucial to its suitability for domestic or drinking purpose.
Commercial agriculture greatly affects water quality in the following ways:
- The washing of fertilizers and pesticides into water bodies from farms.

Answer: Cotyledons are the first leaves to emerge from the soil when a plant germinates. Because they are part of the seed's embryo, they also are known as seed leaves, and provide nutrients to the seedling until its true leaves unfurl and begin the process of photosynthesis.
Explanation:
Answer:
124.6 g/mol will be the molar mass for the unknown non-electrolyte
Explanation:
Freezing point depression → ΔT = Kf . m
ΔT indicates the temperature variation:
Freezing point of pure solvent - Freezing point of solution
Kf is the cryoscopic constant → 29.8 K/m
Generally the unit is °C/m but we have to type the ΔT by K so let's replace the data given → 7.03 K = 29.8 K/m . m
m = 7.03 K / 29.8 m/K = 0.236 mol/kg
m means molality, the moles of solute in 1 kg of solvent. If we want to determine the moles of solute we do this operation:
molality . kg, so we may convert the mass of solvent from g to kg.
50 g . 1kg/1000g = 0.05 kg
0.236 mol/kg . 0.05 kg = 0.0118 moles
Molar mass → g/mol → So 1.47 g / 0.0118 mol = 124.6 g/mol
Chromium phosphate pentahydrate
Answer:
Ca(OH)2 is the base and CaCl2 is the salt
Explanation:
i think this is the answer because calcium hydroxide has hydroxide ions as the only positively charged ion and calcium chloride is a salt.
