Answer : The volume of calcium hydroxide is, 32.89 ml
Explanation :
Using neutralization law,
where,
= basicity of an acid = 1
= acidity of a base = 2
= concentration of hydrobromic acid = 0.389 M
= concentration of calcium hydroxide = 0.0887 M
= volume of hydrobromic acid = 15 ml
= volume of calcium hydroxide = ?
Now put all the given values in the above law, we get the volume of calcium hydroxide.
Therefore, the volume of calcium hydroxide is, 32.89 ml
Answer:
B
Explanation:
FUN is not building block of matter.
Atoms share electons to reach 8 valence electons. these are covalent bonds
Answer: phosphoric acid, H3PO4 (gives pop a tart taste)
% O: 1 mol H3PO4 (4 mol O / 1 mol H3PO4) (16 g / 1 mol O) = (64 g O / 98 g H3PO4) x 100 = 65.3%
% P: 1 mol H3PO4 (1 mol P / 1 mol H3PO4) (31 g / 1 mol P) = (31 g P / 98 g H3PO4) x 100 = 31.6%
Yes it’s a soluble because the carbonate should dissolve in any strong acid with much effervescence
