CH and O is the reactants while CO and H2O is the products
Answer:
For this reason, the existence of Mesosaurus helps support the theory of continental drift; that is, the now-well-attested fact that South America and Africa were joined together into the giant continent Gondwana 300 million years ago before the continental plates supporting them broke apart and drifted.

Answer:
Zymase is acting as a catalyst
Explanation:
Zymase is an enzyme that is naturally produced in yeast. Enzymes are biological catalysts that speed up the rates of reactions in living things.
Zymase catalyses the breakdown of glucose into ethanol and carbon dioxide, which causes the bread to rise.
Zymase speeds up this reaction, but is not physically changed itself. Therefore, it is a catalyst.
Actually, zymase represents a collection of enzymes in yeast, not just one!
Answer:
Option C. Na⁺(aq) and Cl¯(aq)
Explanation:
From the question given above, we obtained the following:
Na₂SO₄(aq) + CaCl₂(aq) —> CaSO₄(s) + 2NaCl(aq)
Ionic Equation:
2Na⁺(aq) + SO₄²¯(aq) + Ca²⁺(aq) + 2Cl¯(aq) —> CaSO₄(s) + 2Na⁺(aq) + 2Cl¯(aq)
From the ionic equation above, we can see that Na⁺(aq) and Cl¯(aq) are present on both side of the equation.
Therefore, Na⁺(aq) and Cl¯(aq) are the spectator ions because they did not participate directly in the reaction.
it may be C. did you get the right answer so you could study it?
