Answers

Answer 1

Answer:

ionic.

Explanation:

the electronegativity difference is greater than 1.7.

Answer 2

The type of bond between boron and fluorine in BF₃ is non-polar covalent bond.

What is covalent bond?

Covalent bond is defined as a type of bond which is formed by the mutual sharing of electrons to form electron pairs between the two atoms.These electron pairs are called as bonding pairs or shared pair of electrons.

Due to the sharing of valence electrons , the atoms are able to achieve a stable electronic configuration . Covalent bonding involves many types of interactions like σ bonding,π bonding ,metal-to-metal bonding ,etc.

Sigma bonds are the strongest covalent bonds while the pi bonds are weaker covalent bonds .Covalent bonds are affected by electronegativities of the atoms present in the molecules.Compounds having covalent bonds have lower melting points as compared to those with ionic bonds.

All of the following undergo hybridization except

A. C
B. Si
C. Mg
D. B

Answers

Answer:

C: Mg

Explanation:

Hybridization of atomic orbitals is a fundamental concept introduced by Pauling that describes the mixing of orbitals at an atom which adds a definite direction to the Lewis - shared electron pair or electron chemical - bond concept.

Carbon(C) can hybridized on sp, sp2 and sp3 simply because it's valence shell gives room for it.

For silicon(si), when forming covalent bonds with other atoms, it's 3s and 3p orbitals are mixed with each other to form new hybrid orbitals.

Magnesium in itself doesn't hybridized except in magnesium hydrides.

Boron orbitals(B): when boron forms bonds with three other atoms like borazine, they are hybridized to either the sp2 or hybridized to the sp3 which occurs when boron forms bonds with four atoms just as is in metal borohydrides.

the one that has one earth goes in rotate the other one goes in revolve

Answer:

causes day and night goes in rotate365 days goes in revolvespins goes in rotate24 hours goes in revolvecauses seasons goes in rotationgo around goes in revolve

Explanation:

Earth is closer to the sun and revolves around it in about 365 days. Sentences: Earth revolves around the sun in 365 days, 5 hours, 59 minutes and 16 seconds. The time a planet takes to revolve around the sun is called a year there for 365 days would be revolve.

It takes the earth abut 24 hours, or one day, to make one complete rotation. At the same time, the earth is moving around the sun. This is called a revolution there for 24 hours is revolve.

the spinning of the earth is called rotation therefore its rotate.

Earth rotates on its axis; this causes us to experience day and night. But Earth's axis is tilted 23.5 degrees (the angle is measured between Earth's equatorial plane and the plane in which it orbits our Sun) therefore causes day and night is rotate.

Instead, Earth has seasons because our planet's axis of rotation is tilted at an angle of 23.5 degrees relative to our orbital plane, that is, the plane of Earth's orbit around the sun. The tilt in the axis of the Earth is called its obliquity by scientists therefore causes of seasons is rotate.

Earth spins around its axis, just as a top spins around its spindle. This spinning movement is called Earth's rotation. At the same time that the Earth spins on its axis, it also orbits, or revolves around the Sun. This movement is called revolution therefore earth spins goes in revolve.

Answers

Answer:

Explanation:

The volume of the two samples of water will be different because volume is the amount of space occupied by a body. It is dependent on the amount of materials it contains.

The 50g sample will have a higher volume compared to the 10g sample. The boiling point and density are intensive properties and do not depend on the amount of matter present. Since both samples are from the same source, they will have the same color.

How is the movement of the electrons different when the atoms are close?

Answers

Answer: The electrons move around between the two atoms. their positive nuclei repel each other. A covalent bond is an electric force of attraction between two atoms that share outer electrons.

Explanation: I hope that helps.

The movement of the electrons different when the atoms are close because when two atoms are very close to each other, the electrons of each atom will then be attracted to both nuclii. If the atoms tries to get two close then the nuclii will repell each other

For better understanding let's explain what the statement means.

Always know that movement of the electrons often differs when the atoms are close because then electrons are said to be inclined or attracted to the other proton only when both protons are closer and the results of what happens if an individual moves the atoms very close to each other they will automatically repel or push away from each other because the same charge is present in them

From the above we can therefore say that the answer the movement of the electrons different when the atoms are close because when two atoms are very close to each other, the electrons of each atom will then be attracted to both nuclii. If the atoms tries to get two close then the nuclii will repell each other is correct
