Answer:
Sodium Hydroxide is an ionic compound formed by two ions, Sodium Na+ and Hydroxide OH− . In order for these two polyatomic ions to bond the charges must be equal and opposite. Therefore, it take one +1 sodium ions to balance the one -1 hydroxide ion. This will make the formula for Sodium Hydroxide NaOH
Explanation:
Answer:
153.8 g/mol.
Explanation:
The molar mass of a compound = ∑ atomic masses of atoms.
<em>∴ The molar mass of CCl₄ = 1(atomic masss of C) + 4 (atomic mass of Cl) </em>= (12.0 g/mol) + 4 (35.45 g/mol) = <em>153.8 g/mol.</em>
Answer:
Biogenesis is the production of new living organisms. Conceptually, biogenesis sometimes attributed to Louis Pasteur and encompasses the belief that complex living things come only from other living things, by means of reproduction.
Explanation:
Answer:
<h3>The answer is 4.65 moles</h3>
Explanation:
To find the number of moles given it's number of entities we use the formula
where n is the number of moles
N is the number of entities
L is the Avogadro's constant which is
6.02 × 10²³ entities
From the question
N = 2.8 × 10²⁴ atoms of Cl2
So we have
We have the final answer as
<h3>4.65 moles</h3>
Hope this helps you
