Answer:
The chloride formed when iron reacts with hydrochloric acid is iron (II) chloride, also known as iron dichloride. The reaction between iron and hydrochloric acid is slower than the reaction with zinc, with much smaller hydrogen bubbles produced.
Answer:
The reaction of iron and hydrochloric acid is slow beacause When dilute Hydrochloric acid is added to iron filings, iron(II) chloride & hydrogen gas is produced. In this reaction iron displaces hydrogen from hydrochloric acid to form iron chloride & hydrogen gas this reaction is a single displacement reaction which reacts slowly.
Explanation:
The boiling point of Sodium chloride(aq) is higher and the freezing point of Sodium chloride(aq) is lower.
The boiling point is the temperature at which the pressure exerted by the surroundings upon a liquid is equal to the pressure exerted by the vapour of the liquid.
Usually, in this context, you would be referring to the boiling and freezing point of a Sodium chloride solution compared to pure H2O.
The boiling point of pure water is 100 degrees Celcius (212 Fahrenheit), and the freezing/melting point is below 0 degrees Celcius (32 Fahrenheit). For a solution, the boiling point is raised and the melting point is lowered.
This means that water will stay liquid for an increased range of temperature. Depending on the amount of Sodium chloride solute in the water, the boiling and melting points may change a few degrees.

Explanation:
An example can be observed when the people add salt on the road surface to avoid icing. The salt water mixture is frozen at approximately a temperature of -21°C and not at a temperature of 0°C as it would be in the case of water. Salt when dissolved in water releases heat, thereby contributing to defrost ice. This is the same principle that is used for car antifreeze, which is to lower the freezing point.

The correct option is COVALENT BONDS.
A Lewis acid is defined as a substance which accept a pair of electron while a Lewis base refers to a substance that donate an unshared pair of electrons to another chemical specie with which it shared the donated pair of electrons.
Lewis acid and Lewis base react together to form salt and water. This type of reaction is called neutralization reaction. The neutralization reaction of Lewis acid and Lewis base involves electron pairs transfer, thus, there is an increase in the number of covalent bonds during this reaction.
Answer:
The correct answer is "covalent bonds".
Explanation:
A covalent coordinated or dative bond is formed when two atoms are linked together, sharing a pair of electrons. But only one of these atoms is the one that brings the pair of shared electrons. For this type of bond to occur, it is required that the donor atom has a pair of free electrons in an outer orbital and the acceptor atom has the capacity to receive that pair of electrons in its last valence layer.
On the other hand, a Lewis base is a substance that can share or donate a pair of electrons, because they have a pair of solitary electrons. A Lewis acid is that substance that accepts or takes a pair of electrons because they have their last electron layer incomplete.
It is then possible to say that an Lewis acid-base reaction is formed by the Lewis acid and base joined by a coordinated covalent bond.
So, the correct answer is "covalent bonds".
