which deflects winds to the right or left

The statement that best describes a chemical property related to the particles that make up a material is A) nickel is a good conductor of electricity because the metallic bonds between its atoms allow electrons to move freely. Option A

Chemical properties describe how substances undergo chemical reactions or interactions with other substances. In this case, the statement about nickel highlights a specific chemical property related to its ability to conduct electricity.

Nickel is a metallic element with a unique atomic structure. It possesses metallic bonds, which involve the sharing of electrons between atoms within a metal lattice. In metallic bonding, the valence electrons of metal atoms are delocalized, meaning they are not strongly associated with any specific atom but are free to move throughout the material.

The presence of these mobile electrons in nickel enables it to conduct electricity effectively. When a potential difference is applied across a conductor like nickel, the mobile electrons can move in response to the electric field, carrying electrical charge from one point to another.

Option B) is incorrect because hardness is a physical property related to the arrangement and bonding of atoms, not a chemical property.

Option C) is also incorrect because malleability is a physical property resulting from the ability of metal atoms to slide past each other when a force is applied, not a chemical property.

Option D) describes the electronic configuration of chlorine, which is a characteristic of its atom but does not directly relate to a chemical property associated with the particles that make up a material.

In summary, option A best describes a chemical property related to the particles that make up a material, specifically nickel's ability to conduct electricity due to the presence of mobile electrons enabled by metallic bonds.

Option A

A covalent compound is a compound with a metal and a nonmetal ion sharing valence electrons (option A).

A covalent compound is a molecule formed by covalent bonds, in which the atoms share one or more pairs of valence electrons.

Covalent bond is a type of chemical bond where two atoms are connected to each other by the sharing of two or more electrons.

Chemical compounds are generally grouped into one of two categories as follows;

Covalent or molecular compounds generally result from two nonmetals reacting with each other. The elements form a compound by sharing electrons, resulting in an electrically neutral molecule.

Answer:

Dissociation

Explanation:

When HCl and NaOH are mixed with water, the HCl and NaOH molecules interacts with the water, forming what is known as ions. Ions are atoms with electric charge.

When HCl, it forms H+ and Cl-. The mixture is acid because what define a mixture as acid is the amount of H+ ions.

When NaOH mixes with water, it forms Na+ and OH- ions. The amount of OH- ions in a mixture defines it as basic.

Explanation:

Nuclear reactions are reactions which occur with changes in the nucleus of an atom. Nuclear reactions usually occur with the release of large amounts of energy and radiation. Radiactive elements are elements that are involved in nuclearbreactions due to the unstable nature of their nucleus. They disintegrate spontaneously with the emission of radiations. The major types of radiations released during nuclear reactions are;

1, Alpha particles - these are positively charged radiations with strong ionizing power. Each alpha particle is a helium nucleus

2. Beta particles - these are very fast moving stream of electrons. They are negatively charged particles .

3. Gamma radiation - is a form of electromagnetic radiation.

In the alpha absorption of Cu-61, the proton number of the atom increases by 2 while the mass number increases by 4 and the Cu-61 atom is changed to Ga-65 atom. The nuclear equation is given as follows:

⁶¹₂₉Cu + ⁴₂He --->⁶⁵₃₁Ga

Answer:

587.5 L (Option A)

Explanation:

The reaction is:

2 C₈H₁₈ + 25O₂  → 16CO₂  + 18H₂O

We know that in STP conditions 1 mol of any gas is contained in 22.4L

Then, we can make a rule of three, to determine the moles of produced carbon dioxide.

22.4L is the volume for 1 mol

376 L will be the volume for  (376 . 1) 22.4 = 16.78 moles at STP conditions.

Stoichiometry is 16:25.

16 moles of CO₂ are produce by the reaction of 25 moles of O₂

Then, 16.78 moles of CO₂ were produced by (16.78 . 25) /16 = 26.2 moles.

Now, the rule of three again.

1 mol of oxygen gas is contained at 22.4L, at STP conditions

26.2 moles might be contained at (26.2 . 22.4)/1 = 587.5 L

Answer:

Helium (He)

Lithium (Li)

Beryllium (Be)

Boron (B)

Explanation:

The chemical elements which have two (2) electron shells are: Lithium and Boron.

Valence electrons can be defined as the number of electrons present in the outermost electron shell of an atom. Thus, valence electrons is typically used to determine whether or not an atom or group of chemical elements found in a periodic table can form a chemical bond with others.

This ultimately implies that, valency is a property that is typically used in determining the chemical properties of chemical elements.  

An electron shell can be defined as the outermost shell of an atom around the atomic nucleus. Thus, it is considered to be an orbit accompanied by electrons around the nucleus of an atom.

Answer:

3.18 L

Explanation:

Step 1: Given data

Step 2: Convert P₁ to mmHg

We will use the conversion factor 1 atm = 760 mmHg.

0.985 atm × 760 mmHg/1 atm = 749 mmHg

Step 3: Calculate the final volume of the gas

Assuming ideal behavior and constant temperature, we can calculate the final volume using Boyle's law.

P₁ × V₁ = P₂ × V₂

V₂ = P₁ × V₁/P₂

V₂ = 749 mmHg × 3.65 L/861.0 mmHg = 3.18 L

Pressure is on the y-axis of a typical phase diagram, and temperature is on the x-axis. A phase transition when we cross the lines or curves on the phase diagram.

The pressure and temperature point on a phase diagram where a material's liquid and gaseous phases merge into a single phase.

The merged single phase is known as a supercritical fluid above the critical point temperature.

Phase diagrams are graphical representations of the connections between the various phases that appear in a system under equilibrium conditions.
