Answer:Therefore, there must be a direct relationship between these volumes of gases and the number of molecules they contain. Avogadro's law says that: Equal volumes of different gaseous substances, measured under the same pressure and temperature conditions, contain the same number of molecules.
Explanation:I hope it works for you.
Let the atomic mass of M metal be X.
The formula mass of metal hydroxide, =
Mass percentage of oxygen in metal hydroxide, = 32.8%
Mass percentage is given as:
Substituting the values:
%
The element having atomic mass is copper, .
Hence, In metal hydroxide, the metal M is copper, . Formula of oxide is .
Answer: The final rate will become 9 times of the initial rate.
Explanation: Rate law says that rate of a reaction is directly proportional to the concentration of the reactants each raised to a stoichiometric coefficient determined experimentally called as order.
k= rate constant
x = order with respect to A
y = order with respect to B
n = x+y = Total order
Rate law :, order with respect to A is 0, order with respect to B is 2 and total order is 2.
Given: doubling the concentration of A and increasing the concentration of B by a factor of three.
Thus the final rate will become 9 times of the initial rate.
NaOH will dissociate as Na+ and OH- in the solution.
The BrO2- ion has one more oxygen (a very electronegative element) than does BrO-, hence BrO2- is more electronegative. This weakens the H-O bond which makes it easier for the H to come off as H+ (i.e. act as an acid). HBrO2 is shown below.
<span>O=Br-O-H </span>
<span>By the same argument, HBrO4 is a stronger acid than HBrO3 which is a stronger acid than HBrO2.</span>
