The third reason helped Rutherford to discover the nucleus.
Answer:
8 mol of hydrogen will react with 1 mol of sulfur.
Explanation:
We'll begin by writing the balanced equation for the reaction.
This is given below:
8H2 + S8 —> 8H2S
Now, let us carefully observe the mole ratio of the reactants.
This is illustrated:
The mole ratio of the reactants ( i.e H2 and S8) is 8 : 1
From the balanced equation above,
We can thus, concluded that:
8 moles of H2 will reacted with 1 mole of S8.
Answer: Option (C) is the correct answer.
Explanation:
The degree of randomness or disorder is known as entropy. This means that more randomly or rapidly the molecules of a substance are moving in a container or in the Universe more will be its entropy.
For example, gases move more rapidly that solids or liquids and hence gases have high entropy.
Therefore, we can conclude that entropy measures disorder.
Answer:
The ppm carbon in the seawater is 104.01.
Explanation:
Mass of seawater = 6.234 g
Mass of carbon dioxide gas produced = 2.378 mg = 0.002378 g
1 mg = 0.001 g
Moles of carbon dioxide gas = 
1 mol of carbon dioxde gas has 1 mole pf carbon atoms,then
will have ;
of carbon
Mass of
of carbon ;

To calculate the ppm of oxygen in sea water, we use the equation:
(Both the masses are in grams)

The ppm carbon in the seawater is 104.01.
