Explanation:
breaking a pencil does not alter the chemical properties of the pencil, it merely breaks it into 2 while the rusting of iron is changing the properties chemically because the iron is oxidizing and reacting with the water and oxygen in the atmosphere
Boiling point of the fragments, for example Ethanol is 78 degrees C, and water is 100.
Answer:
the answer is C hope I helped
soluble substances dissolves in solvents
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>.
