Answer:
e. 8.04*10^4
Explanation:
80.4 g converted to mg is 80,400. 8.04*10^4= 80,400
Answer:
The rate would be lower and the concentration of reactants would be lower.
Explanation:
The rate of a chemical reaction depends on the rate constant and the concentration of reactants.
For Ex:
For a reaction experimentally given by A + B ----> C + D
Rate = k[A][B]
where k is the rate constant
[A] = concentration of reactant A
[B] = concentration of reactant B
As the reaction proceeds,the concentration of reactant decrease and concentration of products increase.Rate constant k depends only on temperature and activation energy.Hence it will remain constant throughout the reaction assuming that reaction is carried out at constant temperature and pressure.
Hence rate will depend only on concentration of reactants and hence decrease with decrease in concentration of reactants.
The answer is A.
The molecules in the air located.......below.
Answer:define propose devise state and then submit
Answer:
(a) a carbon–carbon triple bond is shorter than a carbon–carbon single bond.
The given statement is true.This because bond order in of (C-C) bond in triple bond is 3 whereas the bond order of (C-C) bond in single bond is 1. Higher the bond order shorter will be the bond length.
(b) There are exactly six bonding electrons in the oxygen molecule.
The given statement is false. This is because bond order present in oxygen molecule is 2 which means there are 4 bonding electrons in the oxygen molecule.
(c) the (C-O) bond in carbon monoxide is longer than the (C-O) bond in carbon dioxide.
The given statement is false.This because bond order in of (C-O) bond in CO is 3 whereas in the bond order of (C-O) bond is 2. Higher the bond order shorter will be the bond length.
(d) The (O-O) bond in ozone is shorter than the (O-O) bond in oxygen.
The given statement is false. This is because bond order in of (O-O) bond in ozone molecule is 1.5 whereas in the bond order of (O-O) bond is 2. Higher the bond order shorter will be the bond length.
(e) The more electro-negative the atom, the more bonds it makes to other atoms.
The given statement is false. This is because atom with more electro-negative character. Since, they are highly electron rich atoms so they will tend to form less number of bonds with other atom.
