1.Magnetosphere
2.Liquid Outer core
3.Atmosphere
4.Lightening
5.Biosphere
6.Blue
7.Dolphins
8.Hydrosphere
9.Ice Caps
10.Lithosphere
11.Latitude
12.Longitude
Explanation:
The invisible field that protect us from solar radiation is called Magnetosphere.
This protective field is created by movement between solid inner core and earth's Liquid outer core.
The layer of gases is called atmosphere.
In addition to wind , rain , lightening is observed on stormy night.
Because of water earth looks Blue.
Dolphins are just one of the animals that calls the hydrosphere, its home.
Ice caps in the north and south poles.
Rocky layer of solid earth is part of Lithosphere.
Look for the latitude first ,horizontal line ...
Answer:
-2.86x10³ kJ
Explanation:
The enthalpy of a reaction (ΔH) is defined as the heat produced or consumed by a reaction. In the reaction:
2 C₂H₆(g) + 7 O₂(g) → 4 CO₂(g) + 6 H₂O(g)
The ΔH is the heat envolved in the reaction per 2 moles of C₂H₆. 1.43x10³ kJ are involved when 1 mole reacts. Thus, when 2 moles react, involved heat is:
1.43x10³ kJ ₓ 2 = <em>2.86x10³ kJ</em>. As the reaction is a combustion reaction (Produce CO₂ and H₂O), the heat involved in the reaction is <em>PRODUCED, </em>that means ΔH is negative, <em>-2.86x10³ kJ</em>
Inside the stomach, Hydrochloric acid kills micro-organisms in the food. Stomach juices begin to break down <u>proteins</u> to amino acids.
✤ So, Fill the blank with proteins.
<h3>
<u>Explanation:-</u></h3>
- Inside the stomach, the digestion of proteins starts due to the action of pepsin enzyme.
- But this enzyme remains inactive and is activated by the Hydrochloric acid(HCl).
- The Hydrochloric acid also helps in killing the germs and microbes which entered along with food.
- The mucous lines the wall of stomach to protect it from the harm caused by HCl because HCl is a strong acid.
- In stomach, The partial digestion of proteins occur and rest is digested in the small intestine by Trypsin(Pancreatic enzyme) and Intestinal juices.
