Answer: There are four atoms
Explanation: mass of Cl atom is 35.45 amu
Amount of atoms n = m/M = 142 / 35.45 = 4
The answer is 3. The releasing of energy means exothermic reaction. So the ΔH should be negative. And the greatest quantity of energy released means that the greatest number. So according to the table I, the answer is 3.
Answer: The answer is Fossil A is younger than the index fossil.
Explanation: Because it’s the newest layer
Answer:
Explanation:
Given that
d= 35 μm ,yield strength = 163 MPa
d= 17 μm ,yield strength = 192 MPa
As we know that relationship between diameter and yield strength


d = diameter
K =Constant

So now by putting the values
d= 35 μm ,yield strength = 163 MPa
------------1
d= 17 μm ,yield strength = 192 MPa
------------2
From equation 1 and 2

K=394.53
By putting the values of K in equation 1


Now when d= 12 μm


In a car driven by a gasoline combustion engine, heat energy is quickly converted into kinetic energy which results in the motion of the car.
According to the law of the conservation of energy, energy cannot be destroyed or created. It is can only be transformed from one form to another.
