1. Living plants produce glucose in the process of photosynthesis according to this equation: 6 co 2 (g)+6 H 2 O(g)+energy C 6 H 12 O 6 (5)+6 o 2 (g) Is this reaction endothermic or exothermic, and is the value of H positive or negative?

Calculate the molarity of each of the following solutions. part a) 0.12 mol of lino3 in 5.5 l of solution part b) 60.7 g c2h6o in 2.48 l of solution part c) 14.2 mg ki in 100 ml of solution

Ineed ! i have no clue how to do this problem.

The characteristics of two different types of reactions are shown below: reaction a: electrons are gained by the atoms of an element. reaction b: protons are lost by the atom of an element. which statement is true about the atoms of the elements that participate in the two reactions? their identity changes in both reaction a and reaction b. their identity changes in reaction a but not in reaction b. their identity changes in reaction b but not in reaction a. their identity remains the same in both reaction a and reaction b.
