Which of the following reactions is an example of a single replacement reaction?

select one:
a. mg + agno3 --> ag + mg(no3)2
b. fe + o2 --> fe2o3
c. c6h12o6 + o2 --> co2 + h2o
d. h2o --> h2 + o2

Mg + AgNO₃ → Ag + Mg(NO₃)₂

Explanation:

A single replacement reaction is one in which an element gets replaced by another in a compound.

In the reaction

Mg + AgC→ Ag + Mg(NO₃)₂

Ag in AgNO₃ is replaced by Mg to give Mg(NO₃)₂.Only one element is getting replaced and hence it is a single replacement reaction.

the transfer of heat by electromagnetic radiation is called thermal radiation . it is usually carried out by electromagnetic waves in an energy range just below the visible spectrum, which is the infrared range.

so the answer would be radiation.

they all get energy from eating other animals, dead animals to be more precise.

hienas tends to steal pray from other animals. crows and vultures tend to eat dead animals and leftovers.
