Answer:
11.29 kJ (to 4 sf)
Explanation:
Here, ammonia is the limiting reactant.
For the reaction to occur once, 4 moles of ammonia must be consumed.
Thus means that the reaction can occur 0.1579/4=0.039475 times.
Therefore, (286)(0.039475) = 11.29 kJ (to 4 sf)
The correct answer is 2.99 helium atoms.
I hoped this helped!

See detailed explanation.
Explanation:
Hello there!
In this case, according to the given information, it turns out possible for us to tell that neutralization reactions are usually double replacement reactions whereby an acid reacts with a base, commonly a hydroxide, in order to obtain a salt product and water.
They are called neutralization because they look for the neutral pH, 7, as a result of the reaction. Thus, the aforementioned can be depicted by bearing to mind the example of the neutralization of hydrochloric acid with sodium hydroxide to yield sodium chloride (salt) and water:

Answer:
Examples of storage polysaccharides - <u>starch and glycogen</u> and structural polysaccharides - <u>cellulose and chitin</u>
Explanation:
Polysaccharides are the complex carbohydrate polymers, composed of monosaccharide units that are joined together by glycosidic bond.
In other words, polysaccharides are the carbohydrate molecules that give monosaccharides or oligosaccharides on hydrolysis.
The examples of storage polysaccharides are starch and glycogen. The examples of structural polysaccharides are cellulose and chitin.
Most metamorphic rocks form under conditions found a few kilometers under the earth's surface.
