2. Malachi uses some glue to fix a broken plate. He puts the glue under a desk lamp but the glue
doesn't dry. Then he puts the glue out in the sun and it dries. Why does light from the sun dry the
glue when light from the desk lamp does not?
a
Because the glue can take in energy from the light from the sun, but not from the light from
the lamp.
b
Because light from the sun pulls energy out of the glue and light from the desk lamp does
not.
с
Because the sun gives off a type of light that carries energy, and light from the desk lamp
does not
d
Because light from the sun carries heat molecules, and light from the desk lamp does not.

Explanation:
Draw the Lewis dot structure for the compound gallium oxide with the chemical formula Ga2O3
Answer:
Refer to your periodic table. Lewis dot structures are based off the number of valence electrons an atom has.
Looking at the compounds, we can see that Gallium has three valence electrons in its outer shell and oxygen has six. Oxygen and Gallium are going to share electrons with one another, making a V shape in their diagram.
One Oxygen would make a double bond with a Gallium, leaving one valence electron to another oxygen. That oxygen takes that Final electron. It now has 7 in its outer shell. The remaining Gallium and Oxygen do the same double bond as the one before, leaving the 7 valence electron oxygen with one more electron.
The Lewis dot structure of Ga₂O₃ is shown below.
In molecular structure, Lewis structures describe the relationship between molecules' atoms and their lone pairs of electrons. Lewis structures are also used to predict molecular geometry in conjunctions with hybrid orbitals.
Ga₂O₃ is the inorganic compound of gallium (III) oxide. It is a semiconductor with a very wide bandgap. It is widely used in power electronics. It is also used in phosphors and gas sensing.
There are several polymorphs of gallium oxide. The most stable polymorph of gallium oxide is the polymorph of gallium(III)(monoclinic).

in the carbon cycle what primary way that carbon is removed from the atmosphere??
Water and carbon dioxide are byproducts. Notice that photosynthesis and respiration are essentially the opposite of one another. Photosynthesis removes CO2 from the atmosphere and replaces it with O2. Respiration takes O2 from the atmosphere and replaces it with CO2.
When two atoms share six electrons with one another, what type of bond do they form?
O A. a double ionic bond
O B. a triple ionic bond
O C. a double covalent bond
O D. a triple covalent bond
Answer: The answer is D
Explanation:Covalent bonds are formed when atoms share one or more electrons. Ionic bonds are formed when one atom transfers electrons to another atom. how are bond energy and bond strength related? Please give me Brainliest
When two atoms share six electrons with one another, the type of bond do they form is: D. a triple covalent bond.
A covalent bond can be defined as a bond that exists in chemical compounds and it typically involves the sharing of electrons between the atoms of a non-metallic chemical element.
In Chemistry, there are three (3) main types of covalent bond and these include:
A single covalent bondA double covalent bondA triple covalent bondA triple covalent bond is a type of covalent bond that is formed when the two (2) atoms of a non-metallic chemical element share six electrons with one another instead of the usual two in a single covalent bond.
In conclusion, a triple covalent bond is usually stronger than the equivalent single covalent bond and double covalent bond.

Learning Task 3: Answer the following
separate sheet of paper.
Among the three pictures A, B, and C, which of the following will best represent:
ODUK
1. An atom? Why?
2. A cation? Why?
3. An anion? Why?
Explanation:
Picture A which shows an overall negative charge represents an anion. Anion are formed when an atom gains an electron. In doing that, the total number of electrons (negative charge) is greater than the number of protons (positive charge), hence it would have an overall negative charge.
Picture B which shows a neutral charge represents a neutral atom. In an atom, the number of electrons equals the number of protons.
Picture C which shows an overall positive charge represents a cation. Cation are formed when an atom loses an electron. In doing that, the total number of electrons (negative charge) is less than the number of protons (positive charge), hence it would have an overall positive charge.

14) The central iodine atom in the ICl4- ion has __________ nonbonded electron pairs and __________ bonded electron pairs in its valence shell.
Answer:
Two non bonded electron pairs and four bonded electron pairs
Explanation:
An image of the compound as obtained from chemlibretext is attached to this answer.
The ion ICl4- ion, is an AX4E2 ion. This implies that there are four bond pairs and two lone pairs of electrons. As expected, the shape of the ion is square planar since the lone pairs are found above and below the plane of the square. This is clear from the image attached.
The central iodine atom in the ICl4- ion has two (2) nonbonded electron pairs and four (4) bonded electron pairs in its valence shell.
An electron can be defined as a subatomic particle whose net electric charge is negative. A valence electron can be defined as an electron in the outer shell that can eventually participate in the formation of a chemical bond.An electron pair is a group of two electrons of a given atom or shared by two different atoms as a chemical bond.In conclusion, the central iodine atom in the ICl4- ion has two (2) nonbonded electron pairs and four (4) bonded electron pairs in its valence shell.
