14) A lawn fertilizer is rated as 7.04% nitrogen, meaning 7.04 g of N in 100 g of fertilizer. The nitrogen is present in the form of urea, (NH2)2CO. How many grams of urea are present in 100 g of the fertilizer to supply the rated
A lawn fertilizer is rated as 6.50% nitrogen, meaning 6.50 g of N in 100 g of fertilizer. The nitrogen is present in the form of urea, (NH2)2CO. How many grams of urea are present in 100 g of the fertilizer to supply the rated
mr frank has 1.03 kilograms of fertilizer for the plants in his nursery.he wants every plant to get 95 mg of fertilizer 4 times each year.what is the number of plants he could fertilize with that amount? how much fertilizer will
* If 13.3 kilograms of Al2O3(s), 58.4 kilograms of NaOH(l), and 58.4 kilograms of HF(g) react completely, how many kilograms of cryolite will be produced? * Which reactants will be in excess? *What is the total mass of the excess
Urea (NH2CONH2), an important nitrogen fertilizer, is produced industrially by the reaction 2NH3(g)+ CO2(g)--> NH2CONH2(aq)+ H2O(l). Given that delta G = -13.6 kj/mol, calculate delta G at 25 degree C.for the following condition.
Your body deals with excess nitrogen by excreting it in the form of urea, NH2CONH2. The reaction producing it is the combination of arginine (C6H14N4O2) with water to give urea and ornithine (C5H12N2O2). C6H14N4O2 + H2O
Magnesium can be produced by reaction of magnesium oxide (MgO) with silicon (Si). The by-product of the reaction is magnesium orthosilicate (Mg2SiO4). A reactor is charged with 183.0 kg of MgO and 116.0 kg Si. Assume the reaction
Urea (H2NCONH2) is used extensively as a nitrogen source in fertilizers. It is produced commercially from the reaction of ammonia and carbon dioxide. 2 NH3(g) + CO2(g) ---Heat pressure---> H2NCONH2(s) + H2O(g) Ammonia gas at
