1AlBr3+ 3K ---> 3KBr + 1Al
Answer:
I believe the correct answer is a mixture. Most rocks are just different compounds or elements somewhat fused through heat and pressure. The substances are not chemically bonded together which means that they all retain their chemical identity and therefore can be separated by breaking them up. A good example of this is granite where you can see the different compounds that got fused together and can falls apart when you grind it. I hope this helps. Let me know if anything is unclear.

The reaction would shift to the right (forward).
Balanced chemical reaction: Br2(g) + 2NO(g) ⇌ 2NOBr(g)
According to the Principle the position of equilibrium moves to counteract the change.
The equilibrium shift to the right, so more product (nitrosyl bromide) will be produced. If the product is removed, the reactants will react to produce that product and set equilibrium.
Concentration of the reactants (bromine gas and nitric oxide) is reducing, while concentration of product is increasing.
In a chemical reaction, chemical equilibrium is the state in which both reactants and products are present in concentrations which not change with time.
Speed of direct and irreversible chemical reaction are equal

Answer:
Sound is vibrations that travel through a medium, and which are then converted into electrical signals by our brain so that we interpret them as a noise that we hear. These vibrations consist of particles colliding with each other (this is why sound cannot travel through space; there are no particles). At warmer temperatures, the particles that make up air will move faster, so these collisions will happen more frequently. Therefore the vibrations occur more quickly, so sound travels faster and reaches our ears in a shorter amount of time.
The speed of sound can travel faster in hot air than it can in cold air. This is because the molecules of air can move even faster and the vibrations of the sound wave can transmit faster. Sound is a type of mechanical wave, meaning that it requires a medium to transmit energy. Mediums are any substance that has mass and takes up space, from the air in the room to the metal atoms in an iron fence.
