Answer:
0.034 mol (4dp)
Explanation:
Use the formula n = m/M where n= number of moles, m=mass in grams and M=molar mass in g/mol.
Therefore to find how many moles, divide the mass in grams (2) by the molar mass of sodium chloride which is 22.99+35.45

Answer:
(a) Perchloric acid (HClO₄)
(b) Nitric acid (HNO₃)
(c) Bromous acid (HBrO₂)
(d) Phosphoric Acid (H₃PO₄)
Explanation:
Acids are the species which furnish hydrogen ions in the solution. The other specie produced with the hydrogen ion is called its conjugate base.
Thus,
(a) Perchlorate (ClO₄⁻) ion:
The acid that furnish perchlorate ion is <u>perchloric acid (HClO₄)</u>.
(b) NO₃⁻ ion:
The acid that furnish NO₃⁻ ions is <u>Nitric acid (HNO₃)</u>.
(c) bromite (BrO₂⁻) ion:
The acid that furnish BrO₂⁻ ions is <u>Bromous acid (HBrO₂)</u>.
(d) H₂PO₄⁻ ion:
The acid that furnish H₂PO₄⁻ ions is <u>Phosphoric Acid (H₃PO₄)</u>.
Hey there,
Your question states: Why is ice less dense than liquid water?
There reason why Ice is less dense than liquid is because ice has compact molecules that are tight together and they stay still. But as for water, those molecules are lose and they are more free than ice.
Hope this helps.
