What can you conclude about these two reactions based on the chemical equations? reaction a: 6co2(g) + 6h2o(l) + sunlight → c6h12o6(aq) + 6o2(g) reaction b: 2h2(g) + o2(g) → 2h2o(g) + energy a. reactions a and b are both exothermic. b. reaction a is endothermic, and reaction b is exothermic. c. reactions a and b are both endothermic. d. reaction a is exothermic, and reaction b is endothermic

reaction A :  6 CO2 (g)  +6 H2O(l) +sunlight→ C6H12O6(aq)  +6O2(g)

 reaction B: 2H2(g) +O2(g)→ 2H2O (g)  + energy

What we can conclude about  the  above  chemical reaction is that

reaction A  is endothermic, and  reaction B is  exothermic  (answer B)

        Explanation

Endothermic  reaction  is a reaction   that absorb   energy   from  its surrounding.

Exothermic reaction  is  a reaction that releases energy  to the surrounding.

Reaction A : is endothermic since  it absorb  energy  in  form of sunlight  from   its surrounding.

Reaction B   is a exothermic reaction since  it releases  energy  to the surrounding.
