At an oceanic/oceanic plate boundary 2 oceanic plates will collide against each other. The older oceanic plate will sub-duct under the newer one. It will sub-duct into magma, and will melt into it. The plate and magma will create a reaction, and will build up pressure. With enough pressure, magma will erupt creating a volcano.
At decomposition of solid substance with formation of gas leads to increase in an entropy. For example,
60°C
NH₄NO₂(s) = N₂(g) + 2H₂O(l)

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.
Answer:
Protons
Explanation:
Forming the nucleus are two kinds of particles: protons, which have a positive electrical charge, and neutrons, which have no charge. All atoms have at least one proton in their core, and the number of protons determines which kind of element an atom is. For example, an oxygen atom has 8 protons.
