Answer:

The number of protons or electrons in its atomic structure

Explanation:

Elements are substances which constitute the building block of matter. The smallest particles of elements that can ever exist are known as atoms. Atoms of different elements are different in their structure properties. This difference is due to to the number of sub-atomic particles present in the atom of each element.

The three sub-atomicparticles are protons, neutrons and electrons. Protons and neutrons are present in the nucleus of an atom, while the electrons revolve around the nucleus in orbits. The identity of each element is determined by the number of protons present in the atomic nucleus of that element. This is known as the atomic number of that element. For neutral atoms, the proton number is equal to electron number.

For the given element, the electron and proton number are respectively 4, therefore, the atomic number of the element is 4. The element with atomic number 4 is Beryllium.

Explanation:

The mass of the 2.34 × 10²³ atoms of copper is equal to 24.68 grams.

The Avogadro constant can be defined as the proportionality factor that the number of constituent particles in a sample with the amount of substance.

Avogadro’s number can be described as a dimensionless number that represents the number of entities in one mole of any substance. These elementary entities can be molecules, atoms, ions, electrons, or protons, etc.

Avogadro’s constant has a value approximately equal to 6.022 × 10²³ mol⁻¹.

Given, the number of atoms of copper = 2.34 × 10²³

The atomic mass of Cu Copper = 63.5 g/mol

So 6.022 × 10²³ atoms of Cu have mass = 63.5 g

Then 2.34 × 10²³  Cu atoms will have mass = [tex]\frac{63.5 \times 2.34 \times 10^{23}}{6.02 \times 10^{23}}[/tex] = 24.68 g

Therefore, 24.68 grams of Cu are there in 2.34 × 10²³ atoms of Cu.

Answer:

D: When the acidity of a solution increases, the pH increases.

Explanation:

It is totally wrong to assert that when the acidity of a solution increases, the pH of the solution will increase

The right answer is that when the acidity of a solution increases, the pH value decreases.

When two atoms join together they make compounds

Explanation:

A molecule is formed when two or more atoms join together chemically. If atoms combine that are of two or more different elements, we call that a compound. All compounds are molecules, but not all molecules are compounds.

Molarity is the amount of solute in 1L of solution while percent by mass is the ratio of the mass solute to the mass of solution multiplied by 100. Both quantities are used measure the amount of solute in solution.

The question is incomplete however, I will try to explain molarity and percent by mass.

The term molarity means the number of moles of a substance is 1 L of solution while the percent by mass is the ratio of the mass solute to the mass of solution multiplied by 100.

Both molarity and percent by mass shows the amount of solute in a solution.

The process of photosynthesis is the process of converting carbon dioxide and water into energy in the form of carbohydrates using sunlight. Usually done by plants that have leafy za called chlorophyll.

Carbohydrates themselves are formed from the C-carbon, H-hydrogen and O-oxygen components

Rabbit food is carrots that contain carbohydrates, which are part of the photosynthesis process

3. The carrot plant takes in carbon dioxide from the air during photosynthesis.

Reaction

6CO₂ + 6H₂O ⇒ C₆H₁₂O₆ + 6O₂

2. The rabbit eats the carrot plant.

Rabbits meet their carbohydrate source for energy by eating carrots

1. The rabbit decomposes.

Rabbits in time will experience a process of decomposition

4 - Carbon compounds are returned to the soil.

The carbon content in rabbits will also be decomposed into the soil again

Explanation:

An element's location in the periodic table is largely depending on its electrons. The number of valence shell electrons determines its group, and the type of orbital in which the valence electrons lie in determines the element's block. Sometimes during these groups there are more like the alkali metals the non metals and gases :)

2.34 moles

Explanation:

Given that,

Given mass = 16.3 grams

We know that, molar mass of lithium is 6.941 g/mol

Let there are n number of moles. It is given by :

n = given mass/molar mass

[tex]n=\dfrac{16.3\ g}{6.941\ g/mol}\\\\=2.34\ moles[/tex]

So, there are 2.34 moles in 16.3 grams of lithium

Explanation:

-Synthesis reactions are reactions that appear when two distinct atoms or molecules engage to structure a specific molecule or compound. Most of the time, when a synthesis response occurs, electricity is launched and the response is exothermic. However, an endothermic consequence is additionally possible.

-A decomposition response starts offevolved from a single substance and produces extra than one substance; that is, it decomposes. One substance as a reactant and greater than one substance as the merchandise is the key attribute of a decomposition reaction. For example, in the decomposition of sodium hydrogen carbonate (also recognized as sodium bicarbonate)

-A single-replacement response (sometimes referred to as a single-displacement reaction) is a chemical response in which one aspect is substituted for every other factor in a compound, producing a new aspect and a new compound as merchandise

-A double-replacement response (sometimes referred to as a double-displacement reaction) takes place when components of two ionic compounds are exchanged, making two new compounds. A attribute of a double-replacement equation is that there are two compounds as reactants and two distinctive compounds as product

-A combustion response happens when a reactant combines with oxygen, many instances from the atmosphere, to produce oxides of all different factors as products; any nitrogen in the reactant is transformed to elemental nitrogen, N2. Many reactants, referred to as fuels, incorporate normally carbon and hydrogen atoms, reacting with oxygen to produce CO2 and H2O

A chemical reaction may involve one or more reactants to yiled one or more products.

Below we are going to discuss the types of reaction under the following headings;

Synthesis reaction - This is a reaction in which two or more substances come together to yiled a single product.

Decomposition reaction - This involves the breakdown of a substance into new substances.

Single Replacement Reaction- This is a type of reaction in which an atoms replaces another in a compound.

Double Replacement Reaction - This is a reaction in which cations exchange anion partners in a reaction

Combustion - This is a reaction in which a substance is burnt in oxygen.
