Answer:
FALSE
Explanation:
Keratinocytes begin to die in the stratum granulosum is False.
Answer:
They are a base and an acid, so they neutralize each other.
Explanation:
Sodium hydroxide is a strong base. Hydrochloric acid is a strong acid.
They react with (neutralize) each other to form a salt (sodium chloride) and water.
NaOH + HCl ⟶ NaCl + H₂O
Answer:
Explanation:
A testable question is the one which can be answered using experiment and research. A non-testable question is the one which cannot be answered using experimental trials.
Example:
Non-testable: Which is more better ice-cream or chips?
Testable: Which is more better nutritionally ice-cream or chips?
Here, in the non-testable question no parameter was given for comparision and analysis hence, it cannot be tested experimentally. Whereas, in the testable question nutritional quality is to be compared between the two food items.
Answer:The quantum mechanical model describes the allowed energies an electron can have. It also describes how likely it is to find the electrons in various locations around an atom's nucleus.
Explanation:
Answer : The number of free electrons per cubic meter for silver are
Explanation :
To calculate the number of free electrons per cubic meter for silver by using the following equation:
where,
= density of Ag =
= Avogadro's number =
= 107.87 g/mol
Now put all the given values in the above formula, we get:
conversion used :
Therefore, the number of free electrons per cubic meter for silver are
