.500 mol ( 6.02x10^23 molecules/1 mol) = 3.01x10^23
Answer:
density= mass/volume
hence density of gold rock
= 386/20
=19.3 g/cc
Answer:
carbon monoxide, CO, can be thought of as having two ordinary covalent bonds between the carbon and the oxygen plus a coordinate bond using a lone pair on the oxygen atom
Explanation:
Answer:
The correct option is;
A) x = 2, y = 1
Explanation:
Here we have
....................(1)
....................(2)
..............(3)
From experiment (1), (2) it is observed that [A] is held constant and [B] is doubled of which the rate is also observed to be doubled, therefore, when you double a reactant which result in the rate being doubled, the order of the reaction with respect to the reactant is order 1, therefore, y = 1.
Similarly between reaction (2) and (3) when the concentration of the reactant B is doubled and A is held constant the rate of the reaction is multiplied by a factor of 4, therefore, the reaction with respect to that reactant is order 2, therefore, x = 2.
Therefore, the correct option is x = 2, y = 1.
