<u>Answer:</u> The moles of NaOH are 0.25 moles.
<u>Explanation:</u>
To calculate the number of moles, we use the following formula:
Calculations for the moles of NaOH:
Given mass of NaOH = 10 g
Molar mass of NaOH = 40 g/mol
Putting values in above equation, we get:
Hence, the moles of NaOH are 0.25 moles.
The pH of an acid is lower than the pH of a base. On the pH scale, 7 is neutral, 1-6 is considered acidic, and 8-14 is considered alkaline.
1 — Element D and A ( Which are Sodium and aluminium )
2 — ( 2 + 8 + 3 = 13 electrons total ) Element A Because it's atomic number is 13.
3 — Element E Is stable. ( Which is Argon )
( Note, Elements which has 8 election on its outermost cell is stable. ( Helium is exception which is a noble gas but have 2 electrons in outermost cell )
4 — Element F , which is hydrogen. ( Hydrogen is the only element to not have any neutron )
5 — Element D ( Which is sodium )
6 — The element F ( Which is hydrogen ) Don't contain any neutron.
