Which chemical equation represents a redox reaction?(1 point) 1.) Fe2O3(s) + 2Al(s) → Al2O3(s) + 2Fe(l)
2.) CaO(s) + SiO2(s) → CaSiO3(l)
3.) CaCO3(s) → CaO(s) + CO2(g)
4.) TiCl4(s) + 2H2O(g) → TiO2(s) + 4HCl(g)

PLEASE HELP!!!

c. a tree whose roots are surrounded by wet sand.

explanation;

water stress is an important factor limiting the growth and productivity of forests.water stress is the most often cited cause of poor survival and growth of woody landscape plants.

-insufficient soil moisture is the most common form of water stress, but excess moisture that leads to poor soil aeration (hypoxia) can also result in reduced plant vitality. a tree whose roots are surrounded by wet sand would be least likely to experience water stress.
