Salt is usually formed during neutralization reactions, that is the reaction of an acid and a base. This is illustrated as follows:

<span>HX + YOH -->  XY + H2O</span>

where XY is the salt

 

From the given choices, the only pair of acid and base is:

<span>Vinegar and antacids</span>

Answer is: vinegar and antacids.

Neutralizationis is reaction in which an acid (in this example vinegar or acetic acid CH₃COOH)  and a base (in this example antacid, aluminium hydroxide, magnesium hydroxide or some other base) react quantitatively with each other.

Balanced chemical reaction of vinegar and antacid:

2CH₃COOH(aq) + Mg(OH)₂(aq) → (CH₃COO)₂Mg(s) + 2H₂O(l).

Magnesium acetate ((CH₃COO)₂Mg) is a salt.

Which general equation shows a Single-displacement reaction?
Stella [2.4K]
Hello! The answer is D

A good note for these is when there are three elements, one being a singular element and another a compound and there’s a single switch, this could show a single-displacement

When iron metal reacts with oxygen, the reaction can form Fe2O3. Write a balanced chemical equation for this reaction, and find
ryzh [129]
The balanced equation is 
4Fe+3O₂⇒2Fe₂O₃

We know that the mole of Fe₂O₃ is 6, and since the ratio between oxygen and <span>Fe₂O₃ is 3:2, we can see that

3:2 = x:6 (3 oxygen moles can make 2 </span>Fe₂O₃ moles = x oxygen moles can make 6 <span>Fe₂O₃ moles)
</span><span>
Multiply outside and inside (3*6 , 2*x) and put them on opposing sides of the equation

2*x = 3*6
2x=18
x=9
Therefore 9 moles of oxygen is needed.

How is a model of an atom different from a real atom? A. A model of an atom is not as big as an actual atom. B. A model of an at
tatyana61 [14]
The option that would best contrast the real and the model atoms is letter "D. model of an atom is not as small as an actual atom". The size of an atom is said to be no more than 0.1 to 0.5 nanometers. The models are used to proper illustrate the atom's physical attributes. That is why, it needs to be bigger in size.

Which are examples of contact forces?
lesantik [10]

Answer:

Contact force is a force that requires a contact between two bodies and is ubiquitous in nature

Explanation:

The force is distributed in two categories i.e

  • Contact force
  • Non-Contact force

Contact Forces  are the forces which is requires a contact between two bodies to occur.

The Types of contact forces are given below:

  • Frictional Force
  • Tension Force
  • Normal Force
  • Air Resistance Force
  • Applied Force
  •  Spring Force

Some common daily examples of the contact force are

  1. Frictional force between the tyres of a moving vehicle and the road.
  2. Air flowing in opposite direction of a moving object.
  3. Pushing a table with hand and the friction between its base and floor.
  4. Stretching a rubber band with hands etc.

Also non-contact forces are Gravitational force, Electrical force and Magnetic force.
