The energy diagram shown represents the chemical reaction between solid ammonium chloride and solid barium hydroxide octahydrate:

2nh4cl(s) + ba(oh)2 x 8h2o(> 2nh3(aq)+bacl2(aq)+10h2o(1)

the (triangle then an h) for this reaction is 54.8 kj. how much energy would be absorbed if 23.7 g of nh4cl reacts?

12.14KJ

Explanation:

First look at the stoichiometry of the reaction. The molar mass of NH4Cl is 53.5 gmol-1. There are two moles of it so we have 107g. If it takes 107g of ammonium chloride to absorb 54.8KJ of heat, we could relate this to the energy absorbed by 23.7g and obtain the result as shown in the image attached.

answer: a tank of height h is filled with water and sits on the ground. water squirts from a hole at a height y above the ground and has a range r. for two y values, 0 and h, r is zero. determine the value of y for which the range will be a maximum.

explanation:

smooth muscle is composed of involuntary muscles found within the walls of organs and structures such as the esophagus, stomach, intestines, and blood vessels. those muscles push materials like food or blood through organs. unlike skeletal muscle, smooth muscle can never be under your control.
