Given :
Volume of 
, V = 132 mL .
Molarity of , M = 0.1782 M .
To Find :
How many milliliters of 0.2937 M 
are required to titrate 132.0 mL of 0.1782 M solution .
Solution :
Moles of 
:
Now , 1 mole of reacts with 6 mole of .
So , moles of required is :
Volume required is :
Hence , this is the required solution .
Answer:
Polarity results from an unequal sharing of valence electrons. In SO3 there is the sharing is equal. Therefore SO3 is a nonpolar molecule.
Explanation:
Answer:
Salt is a solid
Explanation: Compounds with this kind of electrostatic attraction, called ionic bonds, are almost always solid at room temperature. But table salt can melt into liquid. onsisting of sodium atoms with positive charges and chloride atoms with negative charges
Answer:
D. 5
Explanation:
The coefficient will almost always be the whole number in front of the variable.
example
5(x)= 7
The coefficient would be 5.
Answer:
11.4 moles of H₂SO₄ are needed to completely react the 7.6 moles of Al
Explanation:
The equation indicates that 2 moles of aluminum react to 3 moles of sulfuric acid in order to produce 1 mol of aluminum sulfate and 3 moles of hydrogen gas.
The reaction is: 2Al + 3H₂SO₄ → Al₂(SO₄)₃ + 3H₂
This question can be solved with an easy rule of three. Ratio in the reaciton is 2:3, so we propose:
2 moles of Al react with 3 moles of sulfuric acid
Then, 7.6 moles of Al will react with 11.4 moles of H₂SO₄
