Answer:
Explanation:
When the two atoms are in contact, potassium transfers its outer electron to chlorine which readily accepts it, resulting in both atoms achieving a state of eight outermost electrons. With this electron transfer, the ionic bond in KCl is formed.
Hope this helped!!!
Potassium has just one valence electron and Chlorine has 7 electrons, Chlorine needs just one atom to complete its octet which is provided by Potassium atom for formation of Potassium Chloride (KCl).
What is Chemical Bonding?Chemical bonding is the formation of chemical bonds present between two or more atoms or molecules which give rise to new compound. Bond is formed from electrostatic force present between oppositely charged ions like in ionic bonds or by sharing of electrons like in covalent bonds.
There are two types of Chemical Bonding:
1. Ionic Bonding
It is formed between opposite charged particles like Anion (negatively charged) and Cation (Positively charged) by the strong force of attraction.
For example, KCl formed by the ionic bond formation present between Potassium and Chlorine
2.Chemical Bonding
It is formed between two atoms for completing its octet by sharing of electrons.
For example, [tex]H_2[/tex] formed by sharing the electrons to complete its electronic configuration.
Thus, Potassium has just one valence electron and Chlorine has 7 electrons, Chlorine needs just one atom to complete its octet which is provided by Potassium atom for formation of Potassium Chloride (KCl).

Which of the following is a correct statement?
1 :Vacuum is an opaque body
2 :Reflection takes place from the polished smooth surfaces
3 :Moon is a luminous body in the sky
4 :A pin hole camera can take pictures on moving objects
5 :Shadows are always inverted
Answer:
Reflection takes place from the polished smooth surfaces
Explanation:
A vacuum does not refer to an opaque body. An opaque body does not allow light to pass through it while a vacuum is simply empty space without air.
A smooth polished surface often acts as a mirror, it is a good reflector of light.
The moon is a non luminous body in the sky. It merely reflects the light from the sun.
A Pinhole camera can not take pictures of moving objects because it only focuses on any image placed before it.
Shadows are not inverted, the always appear upright.
Slow cooling of magma leads to the formation of large crystals, such as halite and calcite.

How does increasing the temperature of a system affect the rate of chemical
reactions?
Answer:
Increasing the temperature of a system will increase the rate of a reaction. More particles are moving faster, and have more energy, increasing the overall rate of reaction.

which elements are out of order in terms of atomic mass. co,Ni or Li,be or I,xe
Answer:
The pair co,Ni is out of order in terms of atomic mass
Explanation:
For co,Ni
Atomic mass of Co = 58.9331 u
Atomic mass of Ni = 58.6934
For Li,be
Atomic mass of Li = 6.941 u
Atomic mass of be = 9.012182 u
For I,xe
Atomic mass of I = 126.90447 u
Atomic mass of Xe = 131.293 u

Given the reaction: 4 NH3(g) + 5 O2(g) → 4 NO (g) + 6 H2O When 1.20 mole of ammonia reacts, how many moles of water are produced?
Answer:
When 1.20 mole of ammonia reacts, 1.8 moles of water are produced.
Explanation:
The balanced reaction is:
4 NH₃(g) + 5 O₂(g) → 4 NO (g) + 6 H₂O
By stoichiometry of the reaction, the following amounts of moles participate in the reaction:
NH₃: 4 moles O₂: 5 molesNO: 4 molesH₂O: 6 molesThen you can apply the following rule of three: if by stoichiometry 4 moles of ammonia produce 6 moles of water, 1.2 moles of ammonia will produce how many moles of water?
[tex]moles of water=\frac{1.2 moles of ammonia*6 moles of water}{4 moles of ammonia}[/tex]
moles of water= 1.8 moles
When 1.20 mole of ammonia reacts, 1.8 moles of water are produced.

What do you think happens to the bonds between atoms when substances melt?
Answer:
As a substance melts, and goes from a solid to a liquid state, the kinetic energy of the molecules increases, and the molecules move faster, and they separate further and further away from each other. The intermolecluar forces holding the molecules together become weaker. This is why a liquid can take fill the shape of its container, whereas a solid has a fixed shape.
