A: Trial 1, because the average rate of the reaction is lower.
The rate of reaction is the speed with which reactants are converted into products. It is also the rate at which reactants disappear and products appear. The higher the rate of reaction, the greater the amount of product formed in a reaction.
If we look at the graph, we will realize that trial 1 produces a lesser amount of product than trial 2. This implies that the average rate of the reaction in trial 1 is lower than in trial 2.
Lower average rate of reaction implies lower concentration of the reactants since the rate of reaction depends on the concentration of reactants.
Hence trial 1 has a lower concentration of reactants because the average rate of the reaction is lower.
Answer:
7.92gml-1
Explanation:
water=25.20ml
water+iron=25.92ml
iron=5.7g
P=mass/volume (formula of density)
mass=5.7g
volume=25.92-25.20
=0.72ml
p=5.7/0.72
=7.92gml-1
I believe the answer would be:
A. Three groups of plants—a group fertilized by X, a group fertilized by Y, and a control group with no fertilizer.
I hope this helps.
Explanation:
A coordinate covalent bond is a special type of covalent bond. In normal covalent bond, atoms combines and shares their electrons to form bonds.
- In coordinate covalent bonds, two atoms are bonded in such a way that one member of the pair is supplying both electrons that are shared.
- An atom supplies the lone pair of electrons to the other atom leaving net positive charge on the donor atom and negative charge on the acceptor.
Just like all interatomic bond types, coordinate covalent bond forms in order for atoms to attain stability through filling their outer energy levels like the noble gases. This is why atoms can share electrons, gain or lose electrons to reach this state.
