The element which is most likely to be magnesium  is the element with the electronic configuration same as magnesium.

It is defined as a substance which cannot be broken down further into any other substance. Each element is made up of its own type of atom. Due to this reason all elements are different from one another.

Elements can be classified as metals and non-metals. Metals are shiny and conduct electricity and are all solids at room temperature except mercury. Non-metals do not conduct electricity and are mostly gases at room temperature except carbon and sulfur.

The number of protons in the nucleus is the defining property of an element and is related to the atomic number.All atoms with same atomic number are atoms of same element.

Answer: here u go

Explanation:

The ionization energy can be thought of as a kind of counter property to electronegativity in the sense that a low ionization energy implies that an element readily gives electrons to a reaction, while a high electronegativity implies that an element strongly seeks to take electrons in a reaction.

Answer: Ionization energy is the energy required to remove an electron from a neutral atom in its gaseous phase.

Explanation: Conceptually, ionization energy is the opposite of electronegativity. The lower this energy is, the more readily the atom becomes a cation.

Answer:

Principle stating that specific groups of organisms have followed, or succeeded one another in a definite sequence through Earth history

Explanation:

Principle stating that specific groups of organisms have followed, or succeeded one another in a definite sequence through Earth history describe Faunal succession because it is a principle that indicate that fossil plants and animals succeed each other in a sequential manner even if they occur in different places. Successive strata and faunas are linked together to form composite section in the Earth's history.

Answer:

Chlorine has higher ionization energy.

Explanation:

Sodium is present on left side of periodic table in period 3 while chlorine is present on right side of periodic table in period 3.

As we move from left to right across the periodic table the number of valance electrons in an atom increase. The atomic size tend to decrease in same period of periodic table because the electrons are added with in the same shell. When the electron are added, at the same time protons are also added in the nucleus. The positive charge is going to increase and this charge is greater in effect than the charge of electrons. This effect lead to the greater nuclear attraction. The electrons are pull towards the nucleus and valance shell get closer to the nucleus. As a result of this greater nuclear attraction atomic radius decreases and ionization energy increases because it is very difficult to remove the electron from atom and more energy is required. Thus chlorine have higher ionization energy as compared to the sodium.

Answer:

The answer is A  S8 + O16 → 8SO2

Explanation:

The balanced chemical equation is -:

S₈ + O₂-----> 8SO₂  therefore (d) is correct .

A balanced chemical equation is an equation that has equal numbers of atoms for each element both on the reactant and product sides.

Methods to balance the chemical equation -:

The number of atoms for a given element is calculated by multiplying its coefficient with the element’s subscript in its chemical formula.

The coefficients in front of the formulas to show how many molecules of that material are used or produced.

Answer:

Heat required to melt 42 g if ice is 13,860 J

Explanation:

The amount of heat required to melt  grams of water at 0°C is given as follows;

The mass of the ice (water), m = 42 g

The latent heat of fusion of ice Δ[tex]H_f[/tex]= 330 J/g

Therefore, heat required to melt 42 grams is given as follows;

Heat required to melt ice = Mass of the ice, m × The specific latent heat of fusion of the ice, Δ[tex]H_f[/tex]

Heat required to melt 42 g if ice = m × Δ[tex]H_f[/tex] = 42 g × 330 J/g = 13,860 J

Heat required to melt 42 g if ice = 13,860 J.

Answer:

Mass is measured in kg

Acceleration is measured in m/s^2

Weight is measured in Newtons

Momentum is measured in kg/m^2

Answer:

In general, the word energy refers to a concept that can be paraphrased as "the potential for causing changes", and therefore one can say that energy is the cause of any change. The most common definition of energy is the work that a certain force (gravitational, electromagnetic, etc) can do. Due to a variety of forces, energy has many different forms (gravitational, electric, heat, etc.) that can be grouped into two major categories: kinetic energy and potential energy. According to this definition, energy has the same units as work; a force applied through a distance. The SI unit of energy, the joule, equals one newton applied through one meter, for example. Energy has no direction in space, and is therefore considered a scalar quantity. Energy is a conserved quantity, meaning that it cannot be created or destroyed, but only converted from one form into another. Thus, the total energy of the universe always remains constant. One form of energy can be readily transformed into another; for instance, a battery converts chemical energy into electrical energy.

Answer:

The solution will fit into the container.

Explanation:

The following data were obtained from the question'

Volume of solution = 170 L

Length of container (L) = 2.5 ft

Height of container (H) = 60 cm

Width of container (W) = 0.8 m

Volume of container (V) =?

Next, we shall express the length, height and breadth I the same unit of measurement. In this case, we shall all in centimetres (cm).

For the length:

1 ft = 30.48 cm

Therefore,

2.5 ft = 2.5 ft × 30.48 cm / 1 ft

2.5 ft = 76.2 cm

Thus the length is 76.2 cm

For the width:

1 m = 100 cm

Therefore,

0.8 m = 0.8 m × 100 cm / 1 m

0.8 m = 80 cm

Thus, the width of the container is 80 cm.

Next, we shall determine the volume of the container as follow:

ength of container (L) = 76. 2 cm

Height of container (H) = 60 cm

Width of container (W) = 80 cm

Volume of container (V) =?

Volume = length × width × height

Volume = 76.2 × 80 × 60

Volume = 365760 cm³

Finally, we shall convert 365760 cm³ to litre (L). This can be obtained as follow:

1000 cm³ = 1 L

Therefore,

365760 cm³ = 365760 cm³ × 1 L/ 1000 cm³

365760 cm³ = 365.76 L

Therefore, the volume of the container is 365.76 L

Since the volume of the container (i.e 365.76 L) is bigger than the volume of the solution (i.e 170 L), therefore, the solution will fit into the container.

Explanation:

The question is incomplete because the image of the alcohol is missing. However, I will try give you a general picture of the reaction known as hydroboration of alkenes.

This reaction occurs in two steps. In the first step, -BH2 and H add to the same face of the double bond (syn addition).

In the second step, alkaline hydrogen peroxide is added and the alcohol is formed.

Note that the BH2 and H adds to the two atoms of the double bond. The final product of the reaction appears as if water was added to the original alkene following an anti-Markovnikov mechanism.

Steric hindrance is known to play a major role in this reaction as good yield of the anti-Markovnikov like product is obtained with alkenes having one of the carbon atoms of the double bond significantly hindered.

A stable arrangement of eight valence electrons : ³⁵Cl⁻¹

Chlorine is a halogen gas, located in group 17, p block

Chlorine has an atomic number of 17 and an atomic mass of 35

Electron configuration: [Ne] 3s²3p⁵

If we look at the electron configuration, then Cl will bind 1 more electron so that the configuration is stable like Argon (atomic number 18)

So by binding this one electron, chlorine forms negative ions (anions)

³⁵Cl⁻¹

B. Cl⁻² binds 2 electrons, exceeding the octet rule

C. Cl⁺¹, releases 1 electron, remains unstable

D. Cl, the neutral form of Cl, is still unstable with a 7-electron valence configuration
