A. It is an ionic bond because electrons are being shared
B. It is a covalent bond because electrons are being shared
C. It is an ionic bond because electrons are being transferred
D. It is a covalent bond because electrons are being transferred.
please answer this no links please!!
Based on the nature of the types of chemical bonding, the example illustrates covalent bonding because electrons are shared between the carbon and hydrogen atoms.
Chemical bondingChemical bonding or combination occurs when atoms of elements combine to form products.
Chemical bonding can either be;
ionic bonding orcovalent bondingCovalent bondingCovalent bonding involves a sharing of electrons by the atoms of elements involved.
Since the example shows electrons being shared between carbon and hydrogen atoms, the example illustrates a covalent bonding because electrons are shared between the atoms.

Is each ion stable? Explain.
Answer:
By satisfying the duet rule or the octet rule, ions are more stable.
Explanation:
Ionic bonds are formed through the exchange of valence electrons between atoms, typically a metal and a nonmetal. The loss or gain of valence electrons allows ions to obey the octet rule and become more stable.
The octet rule states that an atom is most stable when there are eight electrons in its valence shell. Atoms with less than eight electrons tend to satisfy the duet rule, having two electrons in their valence shell. By satisfying the duet rule or the octet rule, ions are more stable.

Which of the following atoms would be expected to be diamagnetic in the ground state?
O magnesium (Mg)
O potassiun (K)
O chlorine (CI)
O cobalt (Co)
The atoms that would be expected to be diamagnetic in the ground state is magnesium
The magnetism of an atom refers to its electronic configuration. A diamagnetic atom is an atom whose electrons are all paired.
A paired electron is an electron that occurs in pairs in its orbital shell.
At their respective ground state, the electronic configuration of the given elements are as follows:
The electronic configuration of magnesium is 1s²2s²2p⁶3s². As such its a diamagnetic atom.
The electronic configuration of Potassium is 1s²2s²2p⁶3s²3p⁶4s¹. Hence, Potassium has one unpaired electron in its outermost shell.
The electronic configuration of Chlorine is 1s²2s²2p⁶3s²3p⁵. Hence, Chlorine has one unpaired electron in its outermost shell.
The electronic configuration of Cobalt is 1s²2s²2p⁶3s²3p⁶3d⁷4s². Hence, the unpaired electrons of Cobalt in its outermost shell are three.
Therefore, the atoms that are diamagnetic in the ground state is magnesium.

How long does it take for a car driving at 10m/s to move 200m?
A.
0.05 seconds
B.
2 seconds
C.
20 seconds
D.
2000 seconds
The time taken by the car driving at 10m/s to move 200m is 20 seconds. The speed of car is 10m/s. Thus option C is correct.
What is speed?Speed is defined as a measurement of the length of time it takes for an object to travel a certain distance.
The SI unit of speed is m/s, and speed is defined as the ratio of distance to time.
A change in speed is an example of acceleration because it is a change in velocity. Acceleration could be for positive or negative. Deceleration is another name for negative acceleration.
There are four types of speed.
Uniform speedVariable speedAverage speedInstantaneous speedSpeed can be expressed as
Speed = Distance / Time
Given, Distance = 200 m
Time = 10 m/s
Speed = 200m / 10m/s
= 20 seconds
Thus, the time taken by the car driving at 10m/s to move 200m is 20 seconds. The speed of car is 10m/s. Thus option C is correct.

Using value of 1.1×10−10 for the Ksp, calculate how many milligrams of Ag2CrO4 will dissolve in 11.5 mL of H2O
Answer:
i think it might be 3.8 milligrams but to be honest i dont know im just trying to help
Explanation:
Using value of 1.1×10−10 for the Ksp, 1.0 milligrams of Ag₂CrO₄ will dissolve in 11.5 mL of H₂O.
What is mass?Mass is defined as the quantity of material that makes up a thing, whereas weight is the force that an object produces. A particle's or an object's mass is a dimensionless number that indicates how much matter is present. Gravity and inertia, which are the two main forces influencing how objects move in space, make mass crucial.
Ag2CrO4 dissociates to form Ag2CrO4 (s). aq 2Ag+ + crO4 (aq)
Ksp = [2Ag+] is an expression for the solubility product constant.
[Ag+] = 2x & [CrO4-] = x 1.1 10 10 = 2[CrO4-] (2x)
2(x) = 4x3 / x = [(1.1×10−10)/4]
1/3 = 3.02 x 10-4 M
Determine the number of CrO4- moles dissolved in 10 ml of water.
Molarity of CrO4- is equal to the number of moles of CrO4- divided by the volume in liters (3.02 x 10-4 M) (10 x 10-3 L)
Number of CrO4- moles equals (3.02 x 10-4)(10 x 10-3) = 3.02 x 10-6 mole.
Number of CrO4- = Number of Ag2CrO4 moles
= 3.02 x 10-6 mole
Ag2CrO4's molar mass = 331.73 g/mole.
3.02 x 10-6 mole of dissolved Ag2CrO4 in water
= 0.0010 g,
= 1.0 milligram.
Thus, using value of 1.1×10−10 for the Ksp, 1.0 milligrams of Ag₂CrO₄ will dissolve in 11.5 mL of H₂O.

The phrase which best describes nuclear fusion is: A. the process by which small nuclei combine into a larger nucleus.
A nuclear reaction can be defined as a type of chemical reaction in which the nucleus of an atom of a radioactive chemical element is transformed by either being joined (fusion) or split (fission) with the nucleus of another atom of a radioactive chemical element and accompanied by a release of energy.
Generally, there are two (2) main types of nuclear reaction and these include:
Nuclear fission: it involves the collision of a heavy atomic nucleus with a neutron, thereby causing a split and release of energy.Nuclear fusion: it involves the joining of two smaller nuclei of atoms to form a single massive or heavier (larger) nucleus with the release of energy.In conclusion, nuclear fusion is best described as the process by which small nuclei combine into a larger nucleus, accompanied by a release of energy.
