Alenkasestr [34]

Answer:

See the answer below

Explanation:

Ethane will burn in oxygen to form carbon dioxide and water according to the following balanced equation:

     2C_2H_6+7O_2 ---> 4CO_2+6H_2O

<em>From the equation, it means that for every one mole of ethane, three and a half moles of oxygen gas are required for complete combustion into carbon dioxide and water. Two and three moles of carbon dioxide and water would be produced respectively for every one mole of ethane that burns in three and a half moles of oxygen gas. </em>

A closed metal container that is filled with hot water gets distorted or compressed when it is kept under the tap water. Why?
tino4ka555 [31]

Answer:

Explanation:

The closed metal container will get distorted or compressed due to a combination of two reasons:

1.<em> contraction of the metal container as a result of a reduction in its temperature.</em>

2. <em>a reduction in the pressure inside the container caused by a sudden drop in the temperature of the water inside it. </em>

The tap water causes a reduction in the temperature of both the container and the water inside it. An increase in temperature causes metal to expand and a reduction in temperature causes it to contract. Also, water takes less space than steam. Therefore, a reduction in the temperature of the hot water causes a reduction in the pressure inside the container relative to the outside. This causes the metal container to be compressed.

What step occurs within an inflammatory response
tester [92]

Inflammatory response can be defined is a reaction of the body to injury or destruction of tissues.  This reaction serves to dilute, destroy or simply wall off the agent causing the injury and is localized around the area of injury.

Inflammatory response takes place in the following steps:

1. Tissue damage caused by injury or bacterial infection is detected.

2. Vasodilators and chemotactic factors such as  histamine are released.

3. As a result, there is increased capillary permeability and blood flow to the area.

4. There is migration of phagocytes to the site of infection.

5. Phagocytes and specific serum proteins attack and destroy bacteria.

6. Inflammation dies down once intruder has been destroyed.
