Determining the weight of 100 CDs depends on whether only the CDs are weighed or if the CDs have sleeves or jewel cases. A single CD by itself weighs about 0.58 ounces. Therefore, 100 CDs by themselves weigh 58 ounces.
Plants need nitrates to develop green leaves. Nitrogen, potassium and phosphorus are the three major nutrients plants need to grow successfully. In particular, nitrogen is responsible for foliage development. Plants use nitrogen in the form of nitrates, which is nitrogen mixed with oxygen. They usually absorb nitrates from the soil.
Nitrogen (N) is essential for plant growth and is part of every living cell. It plays many roles in plants and is necessary for chlorophyll synthesis. Plants take up most of their N as the ammonium (NH 4 +) or nitrate (NO 3 -) ion.otassium (K) is one of the essential nutrients and is taken up in significant amounts by crops. Potassium is vital to photosynthesis, protein synthesis and many other functions in plants. Itâs classified as a macronutrient, as are nitrogen (N) and phosphorus (P). Plants take up K in its ionic form (K +).
