Answer:
3.58J/g°C is the specific heat of the metal
Explanation:
The specific heat of a material is defined as the energy that 1g of the material absorbs and produce the increasing in temperature in 1°C. The equation is:
Q = S*ΔT*m
<em>Where Q is energy = 1362J</em>
<em>S is specific heat of the material</em>
<em>ΔT is change in temperature = 42°C - 17°C = 25°C</em>
<em>And m is the mass of the material = 15.2g</em>
Replacing:
S = Q / ΔT*m
S = 1362J / 25°C*15.2g
<h3>3.58J/g°C is the specific heat of the metal</h3>
Answer: This means to find the number of neutrons you subtract the number of protons from the mass number.

The reason why water is so recurrent is because of the general form that says: ACID + BASE → SALT + WATER
I took the liberty of balancing the equations.
Answer:
D. ammonia, because the other three are the only three strong bases in the world (we do not need to memorize base dissociation constant for the test, we just need to know the three strong bases)

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.
