A+ heat -> b endothermic reaction δh (+)

a -> b + heat exothermic reaction δh

if the heat is in the side of reactants of the reaction an increase of temperature will favor the formation of products and vice versa

"based on the reaction given above, as the temperature decreases, the formation of the reactants will:

decrease
increase
remained constant
indeterminate"

The peak wavelength for the blackbody curve of a star is in the uv range. assuming the radiation from this star can reach earth, would you be able to see it?

The scheme below is from a series of reactions that are part of a synthesis of vitamin a. answer the following questions with reference to this scheme. (i) what is "reagent a"? (ii) draw a step-by-step mechanism which explains the formation of compound c from compound b (iii) which reagents would you use to form compound e from compounds c and d (reagents b and c)? for each reagent suggested above in (ii) explain the role of the reagent in the reaction to (iv) form compound e. you may wish to do this by drawing a mechanism. 1. addition of reagent a но reagent a 2. н, о" thо oh нон-с compound a. compound b. compound c .ch-оh 1. reagent b "сно 2. reagent c сh oh compound e. compound d.

Hey can you me with this i really need y’all
