Answer : The correct options are, (C), (D) and (F)
Explanation :
Redox reaction : It is also know as an oxidation-reduction reaction in which the electrons transferred between the two species. In this, one species shows oxidation by losing electrons and another species shows reduction by gaining electrons.
Most of the chemical reactions shows the redox reaction. The chemical reactions like, synthesis, combustion, single replacement, decomposition shows the redox reaction.
As, the reactants of Option A, B and E does not shows redox reaction because in these reactions the metals will not displace the another metal ion due to less reactivity of metal.
While the reactants of option C, D and F shows redox reaction because in these reactions the metals will displace the another metal ion easily due to high reactivity of metal.
The reactivity series is shown below.
The balanced redox reactions will be,
Hence, the correct options are, (C), (D) and (F)
Answer:
Hence the<u> ions per mole</u> are:
In one mole of Li2SO3 , the number of the atoms are
Explanation:
The formula of lithium sulfite is Li2SO3.
It contain Li+ and SO3(2-) ions.This can be represented by :
Hence one mole of Li2SO3 will give 2 Li+ ions and 1 SO3 (2-) ion.
Hence the<u> ions per mole</u> are:
Number of atoms in lithium sulfite depends upon the<u> mass of the Li2SO3 present</u> .
Li2SO3 = 93.94 g/mole
This mass is equal to 1 mole of Li2SO3
Now<u> 1 mole</u> of any substance contain Na atoms . This is known as Avogadro Number.
Hence , if 1 mole of Li2SO3 is present then it contains Na atoms
If other then 1 mole present then number of atoms are calculated by:
Here n = number of moles
if the mass of the compound is given then first calculate the number of moles.
Mixing baking soda and vinegar to make bubbles of carbon dioxide.
Answer:
C2H5
Explanation:
you first find the number of moles of both substances then divide by the lowest number in this case carbon was 1 and hydrogen was 2,515... then you multiply by a whole number which was 2 then it was now C2H5
