H2PO4 is stronger than HPO42 because it has a higher concentration of H+ ions, making it more acidic. H2PO4 has one more hydrogen ion to donate compared to HPO42, which gives it greater acidic strength.
It is stronger.
It has much weaker gravity.
Pluto has a weaker gravity than Earth. In fact, Pluto has a weaker gravity than Earth's moon.
For -5.25, your eye is stronger, and reguires weaker correction. For -5.75, your eye is weaker, and reguires stronger correction. For 0, no correction is required.
Venus has weaker gravity than Earth. The surface gravity on Venus is about 91% of Earth's gravity.

A polyprotic acid can (in a multi-step reaction) donate more than one proton per molecule of acid.E.g. phosphoric acid can do 'the trick' three times:H3PO4 --> H+ + H2PO4-H2PO4- --> H+ + HPO42-HPO42- --> H+ + PO43-
