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.
Nitrogen is essential for the growth of leaves and stems, and it helps to give plants a rich, green color. If it is lacking, plants will be pale and sickly-looking, and the oldest leaves will look worse than the newer ones.
Plants need nitrogen to grow. Plants are not able to use the nitrogen that is in the atmosphere for this, even though there is tons of it available. Itâs just not in a form that plants can use. So they get the nitrogen they need from the soil where bacteria have converted it into a usable form.
