Answer: 
Explanation:
General representation of an element is given as: 
where,
Z represents Atomic number
A represents Mass number
X represents the symbol of an element
Beta decay : In this process, a neutron gets converted into a proton and an electron releasing a beta-particle. The beta particle released carries a charge of -1 units.
The given reaction would be represented as:
For which of the following conversions does the value of the conversion factor depend upon the formula of the substance?
The answer is C
You breath in oxygen and let out carbon dioxide
First, we have to start balancing the equation:
H2O2 + FeSO4 + H2SO4 → Fe2(SO4)3 + H2O
we can see that the number of H atoms on the left side is 4 and on the right side is 2 so we have to make the number of H atoms are equal on both sides
so, we will put 2H2O instead of H2O
H2O2 + FeSO4 + H2SO4 → Fe2(SO4)3 + 2H2O
we can see that number of O on the left side is 10 and on the right side 14
so we will put 2 FeSO4 instead of FeSO4
H2O2 + 2FeSO4 + H2SO4 → →Fe2(SO4)3 + 2H2O
∴ the coefficients of the reactants and products will be in order 1 2 1 1 2
Answer:
C = through filter
Explanation:
If the particle size is is greater than 1000 nm then particles can be separated through the filtration. These particles are large enough and can be seen through naked eye.
If the particles size is between 1 - 1000 nm i.e, 0.001- 1μm then it can not be separated through filtration. The pore size of filter paper is 2μm and particles pas through it. However it can be separated through the ultra filtration. In ultra filtration the pore size is reduced by soaking the filter paper in gelatin and then in formaldehyde. This is only in case of when solid colloidal is present, if colloid is liquid , there is no solid particles present and ultra filtration can not be used in this case.
