<h3>Answer:</h3>
Oxidation number refers to a number given to an atom which shows the number of number of electrons lost (or gained, if the number is negative), by an atom of that element in the compound.
Hence oxidation number of following atoms in given reaction are:
In NaOH:
Na = +1
O = -2
H = +1
In H2:
H = 0
Answer:
1 mole of atoms contains 6.022×1023 atoms. Thus, 0.2 mole of sodium element has 12.044×1022 atoms in it.
Explanation:
Answer:
The answer is
<h2>0.63 g/mL</h2>
Explanation:
The density of a substance can be found by using the formula
From the question
mass = 47 g
volume = 75 mL
The density is
We have the final answer as
<h3>0.63 g/mL</h3>
