Answer:
Combination or synthesis
Explanation:
The chemical reaction is given as:
2N₂ + O₂ → 2N₂O
From the reaction above we see that this is a combination reaction. In a combination reaction, two or more species combines to give a product.
- The formation of compounds from the union of their constituent elements falls into this category of reaction.
This combination reaction is also known as a synthesis reaction.
Covalent bonds form between hydrogen and oxygen atoms in a water molecule as a result of - Sharing of electrons between atoms.
Answer:
Photosynthesis
Explanation:
The process of taking carbon dioxide and water to form glucose is called Photosynthesis.
Answer:
2NaCN + CaCO3 --> Na2CO3 + Ca(CN)2
Explanation:
Knowing the names gets us: NaCN + CaCO3 --> Na2CO3 + Ca(CN)2
Balance: there are two sodiums and cyanides on the product side so add a 2 to the reactant side.
