Number of Atoms in Methanol are calculated as,
Write chemical formula of Methanol,
CH₃-OH
Find out Subscripts:
There is only one subscript (₃) written after Hydrogen, it means there are 3 Hydrogen atoms attached to Carbon atoms.
Add all atoms in molecule:
Carbons = 1
Hydrogens = 4
Oxygens = 1
Total Atoms ______
6 Atoms
<h2>Hello!</h2>
The answer is: 
<h2>Why?</h2>
First, we need to calculate the molecular weight of the acetone (CH3COCH3)
So,
Then,
Second, we need to calculate the mass of the acetone in the bottle
We need to remember that 
So,
Third, we need to calculate the number of moles:
Fourth, we need to calculate the number of atoms:
Remember, 
Therefore,
Have a nice day!
The complete question;
Match each type of titration to its pH at the equivalence point.
Weak acid, strong base
Strong acid, strong base
Weak base, strong acid
pH less than 7
pH equal to 7
<span>pH greater than 7
</span>Answer:
weak acid, strong base - pH greater than 7
Strong acid, strong base - pH equal to 7
Weak base, strong acid - pH less than 7
Strong acids dissociate completely to give out H⁺ ions.
Strong bases dissociate completely to give out OH⁻ ions.
When strong acids and strong bases are mixed the dissociated H⁺ and OH⁻ ions react and neutralise each other, making the solution neutral.
Weak acids cannot completely dissociate, only a fraction of H⁺ ions are dissociated. Same applies for weak bases.
When weak acid and strong base is mixed, whilst the strong acid completely dissociates, weak base only partially dissociates. Therefore the amount of H⁺ ions is greater than OH⁻ ions, overall pH is more acidic, hence less than 7.
When strong base and weak acid are mixed, strong base completely dissociates giving OH⁻ ions and weak acid only partially dissociates, therefore amount of OH⁻ ions is greater than H⁺ ions, more basic hence pH is greater than 7.
Answer:
Al will have 3 dots
S will have 6 dots
Explanation:
Al is in group 13 or roman nummeral 3 so it will have 3 dots. S is in group 16 or roman nummeral 6 so it will have 6 dots.
