What is one advantage to using this form of circuit? (AKS 10b)
O A.

Explanation:

1one electron and -1 for anions

2 O2- indicates an ion of oxygen having two extra electrons. I.e., since an oxygen atom normally has 8 protons and 8 electrons, this ion has 10 electrons (-10 charge) and 8 protons (+8 charge) giving it a charge of -2 (-10 + 8 = -2).

It shows that the mountain may have once been under water and was raised by natural processes. Maybe

The fossil provide scientists about the way this area might have changed over time, the evidence It shows that the mountain may have once been underwater and was raised by natural processes.

Any surviving remnants, impression, or evidence of a once-living creature from a previous geological epoch is referred to as a fossil. Examples include fossilized bones, shells, exoskeletons, animal or microbe impressions in stone, amber-preserved artifacts, hair, petrified wood, oil, coal, and DNA traces.

There are four basic categories of fossils, each generated in a unique method and useful for conserving various kinds of animals. These include genuine form fossils, trace fossils, mold fossils, and cast fossils.

Usually, sedimentary rocks include fossils, however rarely, low-grade, fine-grained metamorphic rocks will as well. Sometimes, after the fossils have been removed, the surrounding rock has developed molds.

Thus, option D is correct.

Answer:

3 valence electrons

The element with the atomic number 113 would fall in the 13th column of the periodic table Group IIIA. This group has an electron configuration that would end as p1 , meaning there would be 3 valence electrons. The valence electrons are the electrons found in the highest energy level in the s and p orbital.

Explanation:

Nihonium has to be the #113 element of the periodic table

A. is the correct answer because Boron has 3 electrons too,

All elements in Group 13 have three electrons in their outermost energy level. The two most popular elements in this group are Boron and Aluminum.

Boron element would have properties most similar to the new element. Therefore, option (A) is correct.

The chemical properties of elements depend on the number of valence electrons in their valence shell. Elements in the same group in the modern periodic table have the same number of valence electrons. Therefore, chemical elements situated in same group of the modern periodic table have similar chemical behavior.

The chemical elements having an identical outer electronic configuration in their atoms are placed in the same group of the periodic table. These valence electrons of an element are responsible chemical behavior and reactivities of the elements.

Therefore, both Boron and a new element with atomic number 113  have three electrons in their valence shells. So they belong to the same group and will have similar chemical properties.

Answer:

The IUPAC name of given compound is 3−5−ethyl−5−−3−methylheptane. Explanation: The parental chain is of 7 carbons with single bonds hence it is heptane. Two substituents ethyl and methyl group are attached from an equal distance. Hence according to the alphabetical order preference, counting starts from carbon which is close to an ethyl group.

Density, [tex]d=2.09\ g/cm^3[/tex]

Explanation:

Given that,

Mass of a flask is 450 g

Volume of benzene added to the flask is 145 mL or 145 cm³

The weight of the flask and benzene is found to be 754 g.

We need to find the density of the benzene.

Weight of benzene added = total weight of flask and benzene-mass of flask

m = 754 g - 450 g

m = 304 g

Density = mass/volume

So,

[tex]d=\dfrac{304\ g}{145\ cm^3}\\\\d=2.09\ g/cm^3[/tex]

So, the density of the benzene is [tex]2.09\ g/cm^3[/tex].

Answer:

Mass = 40.4 g

Explanation:

Given data:

Mass in gram = ?

Volume of SO₂ = 14.2 L

Temperature = standard = 273 K

Pressure =  standard = 1 atm

Solution:

The given problem will be solve by using general gas equation,

PV = nRT

P= Pressure

V = volume

n = number of moles

R = general gas constant = 0.0821 atm.L/ mol.K  

T = temperature in kelvin

1 atm × 14.2 L = n × 0.0821 atm.L/ mol.K   × 273 K

14.2 atm.L = n ×  22.41 atm.L/ mol

n = 14.2 atm.L/22.41 atm.L/ mol

n = 0.63 mol

Mass of sulfur dioxide:

Mass = number of moles × molar mass

Mass = 0.63 mol × 64.1 g/mol

Mass = 40.4 g

Explanation:

When a substance is heated, it gains thermal energy. Therefore, its particles move faster and its temperature rises. When a substance is cooled, it loses thermal energy, which causes its particles to move more slowly and its temperature to drop.

When the temperature of a substance is increased, i.e., if you double the Kelvin temperature of a substance, you double the average kinetic energy of its molecules. When the average kinetic energy of the molecules goes up (a rise in temperature), the average speed of the molecules increases.

Answer:

Examples 1, 3 and 4

Explanation:

An unexcited atom is an atom in the ground state i.e the atom has it's valence electrons in it's lowest energy level possible. This actually implies the normal electronic configuration of the atom. Thus, examples 1, 3 and 4 have the actual electronic configuration with there valence electrons in the lowest possible energy level.

Example 1: 1S² 2S² 2P⁴

Example 3: 1S² 2S² 2P⁶ 3S¹ (There seem to be a mistake in the question provided, P energy level can only 6 electrons not 8)

Example 4: 1S² 2S² 2P⁶ 3S¹

NOTE: If you take a look at example 2, it will be deduced that the 3P energy level has only 3 valence electrons and the last valence electron jumped to 3d energy level; making that atom appear to be in it's excited state.
