Answer:
Moles of sodium = 15.0⋅g22.99⋅g⋅mol−1 = 0.652⋅mol . Given the stoichiometry of the reaction, clearly 0.652⋅mol sodium hydroxide will result.
Explanation:

Before answering the question, one should first calculate the pH for given concentration of LiOH.
As LiOH ionizes as,
LiOH → Li⁺ + OH⁻
So, the concentration of OH⁻ = [OH⁻] = 0.01
Also,
pOH = -log [OH⁻]
pOH = -log [0.01]
pOH = 2
Whereas,
POH + pH = 14
Or,
pH = 14 - 2
pH = 12
Result:
As pH is greater than 7, so the solution is Basic.
it's A. here is the formule for kinetic energy :)
Answer:
Chemical digestion
Explanation:
The type of digestion taking place within the stomach is chemical digestion. When food reacts with stomach acids and other enzymes, a reaction takes place which reduces the food into simpler bits.
- The stomach contains strong digestive acids.
- Cells in the stomach secrete hydrochloric acid to further aid the digestion of the food.
- This way, complex organic molecules becomes broken down into simpler units.
