In what way does the presence of an atmosphere enhance conditions for life on Earth's surface?

Naddik [55]

It makes the Earth livable for us creatures. We get protected from the Sun's harmful rays reaching to Earth, which makes Earth feel comfortable. Atmosphere also contains Oxygen and we rely on that everyday.

How is enthalpy used to predict whether a reaction is endothermic or exothermic?

Radda [10]

Answer:

$329.48 KJ/mol$ heat is released by the combustion of $2 mol$ of methane

Explanation:

The value of enthalpy determines whether the reaction is exothermic or endothermic. If the enthalpy change is positive, then the reaction is endothermic (heat or energy released) and if the enthalpy change is negative then the reaction is exothermic (heat or energy absorbed).

$2CH_4(g)+4O_2(g) => 2CO_2(g)+4H_2O(g)$

$\Delta H \ reaction=[ 2(\Delta HfCO_2)+ 4(\Delta HfH_2O)]-[2(\Delta HfCH_4)+4(\Delta HfO_2)]$

= $2 ( -(393.5 KJ)/mol)-[2( -74.6 KJ/mol)+4(-241.82 KJ/mol)]$

$= -787 KJ/mol-[ -149.2 KJ/mol-967.28 KJ/mol]$

$= -787 KJ/mol+1116.48 KJ/mol$

$=329.48 KJ/mol$

In this question, the enthalpy of formation has positive value and hence the reaction is endothermic in which the heat is released.

What is pancreatitis and what is the basic mechanism that underlies the condition?

svp [43]

Pancreatitis is an inflammation of the pancreas that may be caused by years of heavy consumption of alcohol of gall stones. The pancreas plays major important roles such as secreting digestive juices into the small intestines, which help to digest fats, proteins, and the carbohydrates in food. It also release hormones insulin and glucagon that regulate the blood sugar. Pancreatitis is characterized by a pancreas being inflamed, therefore when this happens the body's normal complex coordination is disrupted and the enzymes in the pancreas are prematurely activated before they exit the organ, which results in these enzymes digesting the pancreatic tissue.
