Answer:
Urea contains more nitrogen
Explanation:
1 mole of Urea contains 2 moles of Nitrogen and 1 mole of ammonium sulfate contains, also, 2 moles of nitrogen.
60g of urea (Molar mass: 60g/mol) contains:
60g × (1mol / 60g) = 1 mole. As 1 mole of urea contains 2 moles of nitrogen, moles of nitrogen are 2.
100g of ammonium sulfate (Molar mass: 132g/mol) contains:
100g × (1mol / 132g) = 0.758 moles.
As 1 mole of urea contains 2 moles of nitrogen, moles of nitrogen are 0.758×2 = 1.516 moles.
That means, <em>urea contains more nitrogen</em>.
Valence electrons is the answer to ur question
The unit pg stands for pictogram. It is one-trillionth of a gram. Because of the very small mass, it is expressed in the prefix form of the base units for convenience. Now, the mass of cofactor a is 41.5 pg per cell. Since there are a total of 105 cells, the total mass would be:
Total mass = 105 cells * 41.5 pg/cell = 4,357.5 pg
Answer:
Because the total energy of the enzyme has been used up and actions already complete
Explanation:
Catalyst are substance known to speed up rate of chemical reaction just like taking a short pathway. When velocity of catalyzed reaction reach maximum, at that moment reaction has reach it full potential (there is an equilibrium in reaction). there won't be any changes on further addition, and mostly indicate that Reaction is Complete
