Answer:
<h3>The answer is 13.87 g</h3>
Explanation:
The mass of a substance when given the density and volume can be found by using the formula
<h3>mass = Density × volume</h3>
From the question
density of metal = 5.78 g/mL
volume = final volume of water - initial volume of water
volume = 24.7 - 22.3 = 2.4 mL
We have
mass = 5.78 × 2.4 = 13.872
We have the final answer as
<h3>13.87 g</h3>
Hope this helps you
Answer: particles become ions when you remove electrons from a neutral atom to get a positive ion or adding ions to a neural atom to get a negative ion.
Answer:
See detailed explanation.
Explanation:
Hello there!
In this case, for the given scenario, we will proceed as follows:
1. Here, we infer that the products are iron (III) hydroxide (precipitate) and calcium chloride:
2. In this step we firstly calculate the moles of both reactants, by using their molar masses 74.093 and 162.2 g/mol respectively:
Now, we calculate the moles of calcium hydroxide consumed by 0.105 moles of iron (III) chloride by using the 3:2 mole ratio between them:
Thus, we infer that calcium hydroxide is in excess as 0.189 moles are available for it but just 0.157 moles react and therefore, iron (III) chloride is the limiting reactant.
3. Here, we use the moles of iron (III) chloride we've just computed, the 2:2 mole ratio with iron (III) hydroxide and its molar mass (106.867 g/mol) as shown below:
