Write a balanced equation (including phases) for the chemical reaction between dihydrogen phosphate ion (H2PO4‒) and water. La
bel the acid, the base, the conjugate acid, and the conjugate base.
1 answer:
Answer:The Acid is dihydrogen phosphate (H2PO4-), H2O is the base, H3O+ is the conjugate acid, HPO42- is the conjugate base.
Explanation:
when dihydrogen phosphate (H2PO4-) ion reacts with water (H2O), it produces hydrogen phosphate ion (HPO42-) and hydroxonium ion (H3O+) following the reaction;
H2PO4- + H2O HPO42- + H3O+
According to Bronstead-lowry, an acid is a proton donor while a base is a proton receptor. The conjugate acid is the product after the base as accepted the proton while a conjugate base is the product after the acid has donated the proton.
The Acid is dihydrogen phosphate (H2PO4-) because it donates a proton to water which makes H2O the base.
H3O+ is the conjugate acid which is the product after the base accepted the proton while HPO42- is the conjugate base.

Answers:
B, C, and D
Explanation:
B. True. The direction is generally northward, although it turns more to the east off North Carolina (see map).
C. True. The Gulf Stream is an ocean current, because it flows across the Atlantic Ocean.
D. True. It transports warm water from the Gulf of Mexico and the Caribbean towards Iceland and the British Isles.
A. <em>Wrong</em>. The Gulf Stream is <em>not cyclic</em>. It always flows in <em>the same direction, </em>roughly northeast.
