Answer:
The bronsted- Lowry acid is H₂PO₄⁻
Explanation:
Bronsted-Lowry acid donates a proton (H⁺)
H₂PO₄⁻ + OH⁻ → HPO₄²⁻ + H₂O
In the reaction above, H₂PO₄⁻ is donating the proton to OH⁻ resulting in H₂O and the deprotonated species. This makes it a bronsted-Lowry acid.
Answer:
D. ionic sodium phosphate (Na3PO4)
Explanation:
To understand what makes a material hard, it is necessary to look at the atomic structure of its crystals. ... In diamonds, however, the carbon atoms are bound together in a tetrahedral formation, a shape that is extremely rigid. Combined with the strong carbon to carbon bonds, it makes diamond extremely hard
