The train cars moves in the same direction when the engine car begins
moving to the left.
<h3>What is Law of magnetism?</h3>
The law of magnetism states that like poles repel and unlike poles attract.
In substances which have magnetic field, they are known to attract each
other.
The engine and train car are highly magnetized which results in them
moving in the same direction when they are in close contact with one
another.

<h3>
Answer:</h3>
Sodium
<h3>
Explanation:</h3>
- To answer the question we need to know a few things.
What are cations?
- Cations are positively charged ions that are formed when an atom of an element loses an electron(s).
What elements form cations?
- Metallic elements form cations since they react by losing electrons thus forming ions with a positive charge.
- For example, alkali metals such as sodium form cations with a charge of +1.
- In this case, sodium will form a cation with a charge of + 1, Na⁺
What are negatively charged ions?
- Negatively charged ions are known as anions.
- They are formed by non-metallic elements such as sulfur, argon, silicon, etc.

Explanation: ok 11 plus 1 is 12
Answer:
PCl₅(g) + heat ↔ PCl₃(g) + Cl₂(g)
On increasing the concentration of PCl5(g), the equilibrium will shift in forward direction and produce more PCl₃.
Explanation:
According to Le Chatlier's Principle " If we apply any external stress on a system at equilibrium, the system minimize the effect by itself to regain equilibrium". In above reaction initially the system is in equilibrium. when we increase the concentration of reactant (PCl₅), the system goes to forward and produce more product (PCl₃).
After some time reaction will go in backward direction to regain equilibrium position while consuming PCl₃ and Cl₂. Finally reaction will again in equilibrium position.
