Answer:
Explanation:
The intermediates are the products of all the steps of the reaction pathway, with the exception of the last one. So the intermediates will be:
- N2O2 from the first step
- N2O from the second step
The list from reactant to final product:
<em>Note: the water is considered a by-product, given that is not the product of interest in this steps.</em>
Answer:
True
Explanation:
The speed that electromagnetic waves will travel within any medium is the same as those without a medium. The speed of electromagnetic wave is a constant and does not depend on the material of the medium.
- Electromagnetic waves are waves that do not require a material medium for their propagation.
- They are able to pass through vacuums and mediums with particles at constant speed.
- It is mechanical waves whose speed is medium dependent.
- Mechanical waves have varying speed based on the mediums they move through.
The answer would be decomposers
question 1
moles = mass/molar mass of Al(OH)3
convert Kg to g
that is 1.09 x 1000=1090g
moles is therefore=1090g/78(molar mass of Al(OH)3)= 13.974 moles
question 2
moles=2.55g/327.2(molar mass of Pb(CO3)2= 7.79 x 10^-3 moles
from avogadro constant
1moles=6.02 x10^23 formula units
what about 7.79 x 10 ^-3
={(7.79 x 10^-3)moles x ( 6.02 x10^23)} /1 mole=4.69 x10^21 formula units
