The answer is A since I looked it up :)
Answer:
The correct option is: E. No precipitate will form.
Explanation:
A solubility chart refers to the list of solubility of various ionic compounds. It shows the solubility of the various compounds in water at room temperature and 1 atm pressure.
Also, according to the solubility rules, the salts of chlorides, bromides and iodides are generally soluble and mostly all salts of sulfate are soluble.
Since, all the compounds formed in this double replacement reaction are soluble in water. Therefore, no precipitate will be formed.
ZnSO₄ (aq) + MgCl₂ (aq) → ZnCl₂ (aq) + MgSO₄ (aq)
The right answer is the third option:
10^-3 L / 1 mL
That conversion factor may be derived from 1 L = 1000 mL
=> 1 L / 1000 mL = 1
=> 10 ^ - 3 L / 1 mL = 1
So, you can mutilply by the conversion factor 1 * 10^ -3L / 1 mL because it the equivalent to 1.
The other options are not valid. Let's see why:
1 KL = 1000 L => 1KL / 1000 L = 1
=> 10 ^ - 3 KL / 1 L, which is contrary to the first option.
In that same way you can find the righ conversion factors that relate L with cL, and L with d and you will discard the other options.
Answer:
I personally think it would be all of the above
Mass of Aluminum = 157.5 g
<h3>Further explanation</h3>
Given
17.5 g of Hydrogen
Required
Mass of Aluminum
Solution
Reaction
2Al + 3H₂SO₄ → Al₂(SO₄)₃ + 3H₂
mol Hydrogen :
= mass : molar mass
= 17.5 g : 2 g/mol
= 8.75
From the equation, mol Al :
= 2/3 x mol H₂
= 2/3 x 8.75
= 5.83
Mass Al :
= 5.83 x 27 g/mol
= 157.5 g
