Why rusting takes place more readily in coastal areas

Answers

Corrosion is a better word to use as Iron is the metal that 'rusts' and it happens more in coastal areas because coasts are humid. Humidity reacts with the metal causing it to corrode and wakening it

Which two factors must be equal when a chemical reaction reaches equilibrium?(1) the concentration of the reactants and the concentration of the products
(2) the number of reactant particles and the number of product particles
(3) the rate of the forward reaction and the rate of the reverse reaction
(4) the mass of the reactants and the mass of the products

Answers

The correct answer is option 3. Equilibrium is achieved in a chemical reaction when the rate of the forward reaction is the same for the rate of the backward reaction and when the reaction has stopped.

Which statement describes what occurs as two atoms of bromine combine to become a molecule of bromine?(1) Energy is absorbed as a bond is formed.
(2) Energy is absorbed as a bond is broken.
(3) Energy is released as a bond is formed.
(4) Energy is released as a bond is broken.

Answers

Answer:

The correct answer is option 3.

Explanation:

Whenever there is a formation of bond between 2 atoms energy is released. This energy release is due to stability gained by the atoms after the formation of a bond that is why extra energy is released as a heat into surroundings. Exact process is occurring when 2 bromine atoms form bond to give molecule of bromine.

Whenever there is a dissociation of bond between 2 atoms energy is given. The energy provided externally so as to break the stable bond present between the atoms.

Br + Br -> Br2 (covalent bond)

forming of bonds releases energy, since the Br's are at a lower energy state as Br2
