You find the molar mass of NaCl first, by adding the weight of both to get 58.44g.
Then you set up the equation with what is given:
2.4mol NaCl and multiply it by 58.44g NaCl to get your answer= 140.256g
Answer:
The answer is
<h2>
</h2>
Explanation:
To find the number of atoms given the number of moles we use the formula
N = n × L
where
N is the number of entities
n is the number of moles
L is the Avogadro's constant which is
6.02 × 10²³ entities
From the question
Substitute the values into the above formula and solve
That's
<h3>
</h3>
We have the final answer as
<h3>
</h3>

Answer:
C
Explanation:
When two atoms share electrons, a covalent bond is formed. The more electrons shared between atoms, the stronger the bond. Single bonds have two electrons shared, double bonds have four electrons shared, and triple bonds have six electrons shared.
Therefore, triple bonds are the strongest as they require more energy to break.
Hope that helps.
Answer:
D. Different functional groups and different physical and chemical properties
Explanation:
A functional group is an atom or group of atoms within a molecule that determines the chemical and physical properties of the compounds it appears in.
The functional group of an alcohol is the -OH group while that of an ether is an oxygen atom bonded to two alkyl or aryl groups, R-O-R'.
Based on the above;
Option A is wrong because they have different functional groups, hence different properties
Option B is wrong because they don't have same functional group even though their properties are different
Option C is wrong because they have different properties even though they have different functional groups
Option D is correct because they have different functional groups and different properties.
