Explanation:
The term reproductive strategy is loosely used to refer to the way an animal mates and/or raises offspring. ... It could also refer to semelparous reproduction, one reproductive episode in a lifetime, or iteroparous reproduction, multiple reproductive episodes over the course of an organism's life.
Answer:
Crisscross method is simply writing the charges crossly near each element. Since oxidation number of Mg (metal) is +2 and oxygen (nonmetal) is -2, if we cross them and write next to each; we get Mg2O2 .
b
Explanation:
oh will combine with h to form water
Answer:
a. Decomposition.
Explanation:
A combination reaction is a reaction where two or more elements or compounds combine to form a single compound. Such reactions may be represented by equations of the following form: X + Y ⇒ XY.
- Decomposition reactions are a type of chemical reaction that involves breaking down a compound into smaller compounds or individual elements.
- A single-displacement reaction, also known as a single-replacement reaction, is a reaction by which one element replaces other element in a compound.
- A double displacement reaction, also known as a double replacement reaction or metathesis, is a type of chemical reaction where two compounds react, and the positive ions (action) and the negative ions (anion) of the two reactants switch places, forming two new compounds or products.
Hence, the answer is a decomposition reaction.
It's a single- replacement reaction so Mg+ 2HCl ➡️ H2+ MgCl2
