Number of moles of the gas, Temperature and the volume of the gas.
Answer/Explanation:
A theory has lots of scientific evidence to back it up. We know this to be true based on lots of different diseases and studies of their spread.
A hypothesis is more of a starting point - an educated guess based on limited evidence. It requires further testing before becoming a theory.
A law is something that can be generalized to lots of contexts, and is universal. Such as the law of thermodynamics.
How many moles of oxygen atoms are present in 5
moles of Mg3(PO4)2
All you have to do is to create
a ratio between the molecule and the oxygen atom.
5 moles of Mg3(PO4)2 (4x2 moles
O/1 mole Mg3(PO4)2) = 40 moles of oxygen
Answer: 131 g of bromine is required.
Explanation:
The balanced equation will be :
To calculate the moles, we use the equation:
moles of 
According to stoichiometry :
2 moles of require = 3 moles of 
Thus 0.544 moles of require=
of
Mass of 
Thus 131 g of bromine is required.
