Answer:
80g=0.08kg
20cm=0.02m
density=m/v
= 0.08/0.02
=4kg/m^3
it is less than density of water so it floats
Magnetic fields are created due to high levels of electricity
Explanation:
The chemical elements goes from 30g to 15g to 7.5g to 3.75g.
Therefore, it has gone through 3 half lives.
<span>The first thing that needs to be done in order to answer the question above is to balance first the chemical equation by seeing to that the number of moles of a certain element on the reactant side is equal to the number of moles in the product side. 4NH3 + 5O2 4NO + 6H2O The mole fraction between the NH3 and NO is therefore 4:4 or 1:1.</span>
