The rails expand during the heat of a summer day
Answer:
The kinetic energy of an object is also measured in joules. Anything that is moving has kinetic energy, but various factors affect how much kinetic energy an object has. The first factor is speed. If two identical objects are moving at different speeds, the faster object has more kinetic energy. In physics, the kinetic energy of an object is the energy that it possesses due to its motion. It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity. Having gained this energy during its acceleration, the body maintains this kinetic energy unless its speed changes. The same amount of work is done by the body when decelerating from its current speed to a state of rest.
Explanation:
Answer:
Hexane.
Explanation:
Hello!
In this case, since the general reaction of the compound C4H14 with chlorine is:
Which stands for a substitution chemical reaction in which one chlorine is able to replace one hydrogen and therefore hydrogen chloride gives off; we infer that the initial compound, C4H14, shows off the 
formula characteristic of alkanes; in such a way, as it has six carbon atoms, we infer it is hexane.
Best regards!
Equilibrium
N₂(g) + 3H₂(g) ⇔ 2NH₃(g)
If the concentration of the reactants is added, the system will reduce the concentration of the reactants by shifting towards the products and vice versa if the concentration of the reactants is decreased the system will shift towards the reactants.
ammonia is removed from the reaction mixture ⇒ it means the ammonia is reduced then the equilibrium shifts to the right
