Answer:
Double replacement:
Explanation:
Chemical equation:
2AsCl + 3H₂S → As₂S₃ + 6HCl
The given reaction is double displacement reaction. In this reaction arsenic trichloride and hydrogen sulfide react and produced arsenic sulfide and hydrogen chloride. In double displacement reaction both anion an cation of reactants are exchanged with each other.
Double replacement:
It is the reaction in which two compound exchange their ions and form new compounds.
General equation:
AB + CD → AD +CB
Answer:

Explanation:
Given
485 L
Required
Determine the measurement not equal to 485L

<em>From standard unit of conversion;</em>
1 KL = 1000 L
<em>Multiply both sides by 485</em>


<em>Divide both sides by 1000</em>

---- This is equivalent
---------------------------------------------------------------------------------------------

<em>From standard unit of conversion;</em>
1000 mL = 1 L
<em>Multiply both sides by 485</em>


Convert to standard form

Hence;
is not equivalent to 485L
---------------------------------------------------------------------------------------------

<em>From standard unit of conversion;</em>
100 cL = 1 L
<em>Multiply both sides by 485</em>


Convert to standard form
---- This is equivalent
---------------------------------------------------------------------------------------------
μL
<em>From standard unit of conversion;</em>
1000000 μL = 1 L
<em>Multiply both sides by 485</em>


Convert to standard form
---- This is equivalent
From the list of given options;
is not equivalent to 485L
Answer:
449 (g K) / 39.1 (g/mol K) = 11.5 mol K
Explanation:
Potassium has atomic number 39.1
amount of K in 449g sample = 449/39.1 = 11.5 mol
The answer to this would be helium
