Un grupo de estudiantes utilizan un aparato para estudiar la tranferencia de energia durante la reaccion quimica entre pedazos d

e cascara de huevo( carbono de calcio) y vinagre(acido acetico). Durante el experimento utilizan la misma masa de cascara de huevo pero varian la concentracion del vinagre, (1%, 3% y 5%). Contesta:1. Explica por que la transferencia de energia no es la misma entre las tres pruebas del experimento.2. Describe como se podria modificar el aparato para que pueda medir con MAYOR EXACTITUD la tranferencia de energia en cada reaccion​

Explanation:

It correctly reads;

A group of students use a device to study the energy transfer during the chemical reaction between pieces of eggshell (calcium carbon) and vinegar (acetic acid). During the experiment they use the same mass of eggshell but the concentration of the vinegar varies, (1%, 3% and 5%). Answer:

1. Explain why the energy transfer is not the same between the three tests of the experiment.

2. Describe how the device could be modified so that it can MORE ACCURATELY measure the energy transfer in each reaction.

Which disorder, diagnosed in the 1800s, was believed to be caused by a woman experiencing "wandering movements of the womb"?
HACTEHA [7]
A 2nd-century hysteria was caused by the belief that the uterus could move freely within the body in search of fluid and cause specific symptoms depending on the areas the uterus was displaced to. Called the wandering womb disorder, the womb was believed to be a living thing within a living thing.

What are some benefits of enzyme production in the process of digestion.
Rudik [331]

Answer:

<u><em>definition;</em></u>

enzymes are protein that catalyze speed up the biochemical reactions and are not changed during the reaction . the molecules at which enzyme work  are called <em>substrate </em> and enzymes convert them into  different molecules called products.

<em><u>benefits of enzyme in digestion ;</u></em>

enzyme lower the activation energy in several ways. they may alter the shape of substrate and reduce the requirement of activation energy . enzyme may also  lower activation energy by bringing substrate in correct orientation to react . enzyme break down <em>carbohydrates, lipids and  proteins  </em>which are component of human food .In digestion larger molecules are broken into smaller molecules like amino acids ,simple sugars ,fatty acid ,vitamins ,salts and water to provide to cells.  these molecules are  a part of larger molecules like protein ,polysaccharids  and lipids . enzymes like amylaze, lypase   ,salivary amylase, pepsin ; it is a very strong protein digesting enzyme it is released in its inactive form pepsinogen  which is converted into pepsin with the help of H-C-L  hydrochloric acid it takes part in digestion in stomach
