There are six common types of reactions:
1. Combination
2. Decomposition
3. Single Displacement
4. Double Displacement
5. Combustion
6. Redox
The reaction: SO₃₍g₎ + H₂O₍l₎ → H₂SO₄₍aq₎ is classified as a combination reaction. This is because for combination reactions, two (or more) reactants form a single product. On the other hand, decomposition reactions involve a single reactant breaking down into two or more simpler substances. Displacement reactions involve a more active element displacing a less active element from a compound. Meanwhile, combustion reactions involve a carbon-containing compound reacting with oxygen to form carbon dioxide and water. Redox reactions then involve exchange of electrons between species.
the pH numbers that are acidic above is 3 and 5
Answer:
I think it is true i hope its right
Answer:
Carbon Dioxide
Explanation:
Plants inhale Carbon Dioxide and exhale Oxygen
Answer:
The "right" answer is 4. When matter is a gas, the particles flow freely, having no fixed shape or volume and contain a lot of extra space between particles.
However the last part, "...with a lot of empty space between them giving it energy" is (I'm fairly certain) incorrect. The relationship is the other way. Energy is added to the system, causing the particles to move more, thus building up the space between them.
