Melting point is dependent on the intermolecular forces which means the bonds between the molecules of bromine as it is a simple molecular structure
Answer:
D.
Explanation:
It pushes the experimental results one way or another. Less reliable.
Answer:
The answer to your question is: 0.0265 moles of H3PO4
Explanation:
Data
[H3PO4] = ?
Volume Ba(OH)2= 0.186 l
[Ba(OH)2] = 0.214 M
Equation
2H3PO4 (aq) + 3 Ba(OH)2 (aq) ---> 6H2O (l) + Ba3(PO4)2 (s)
Process
Molarity = moles / volume
moles = Molarity x volume
moles of Ba(OH)2 = 0.214 x 0.186
= 0.0398
Rule of three
2 moles of H3PO4 -------------------- 3 moles of Ba(OH)2
x -------------------- 0.0398 moles of Ba(OH)2
x = (0.0398 x 2) / 3
x = 0.0265 moles of H3PO4
Ssssssssssssssssssssssssssss
I am guessing you want us to balance this equation so.
To balance, we add another molecule of HCl to the left side of the equation and another molecule of water (H20) to the right side of the equation to give:
<span>Mg(OH)2 + 2HCl = MgCl2 + 2H20 </span>
