which side of the periodic table are the metals on

Answer:

Explanation:

The collision theory explains why reactions occur between atoms, ions, and molecules. With the increase in temperature, there is an increase in the number of collisions. Increasing the concentration of a reactant increases the frequency of collisions between reactants and will, therefore, increase the reaction rate.

Oxidation reaction

The kind of reaction involving the transfer of electrons or hydrogen away from a molecule is called oxidation.

In the same vein, the molecule that receives the electron or the hydrogen atom is said to be reduced. This means that oxidation cannot exist in isolation without reduction.

In other words, oxidation is defined as:

Answer:

liquid no not a solid

Explanation:

When you put the substance in a 25 mL beaker. then the state of matter is solid, appearance and texture are powdered and crystalline structure is not solid(powder).

The term "crystalline structure" refers to the arrangement of atoms, ions, or molecules in a crystalline solid. A crystalline solid is a type of material where the constituent particles are arranged in a regular, repeating pattern. This regular arrangement results in a characteristic geometric shape for the crystals. Examples of crystalline solids include salt, sugar, and diamond.

On the other hand, the term "state of matter" refers to the physical form in which matter exists. There are three primary states of matter: solid, liquid, and gas.

Solids have a definite shape and volume and their constituent particles are held tightly together by strong intermolecular forces.

Liquids have a definite volume but no definite shape, and their constituent particles are held together by weaker intermolecular forces.

Gases have no definite shape or volume, and their constituent particles are far apart and move freely.

Other states of matter, such as plasma and Bose-Einstein condensate, also exist but they are less common in everyday life.

Therefore, the state of matter: is solid, its appearance and texture: are powdered, and the crystalline structure: is not solid.

Answer:

P = 5, Ar = 8, C = 4, Ni = 2

Explanation:

All these answers can be based off which column of the periodic table each element is in. This does exclude the transition medals in between the 2nd and 13th columns. Column 1 = 1, Column 2 = 2, Column 3 = 3 and so on. Transition metals can be determined based on their electron configuration, which in this case, Ni has 2 electrons in its outer most shell.

Answer:

the pH of the acid is the property that determines whether an acid is a strong acid or a weak acid

Answer:

C. it involves the sharing of electrons

Explanation:

A covalent bond consists of the mutual sharing of one or more pairs of electrons between two atoms. These electrons are attracted by the two atomic nuclei. A covalent bond forms when the difference between the electronegativities of two atoms is too small for an electron transfer to occur to form ions.

The molality of the solution is 1.4 moles per kilogram (molal).

The molality of the solution is equal to the number of moles of sugar (solute) divided by the number of kilograms of water (solvent). Hence, the molality is determined below:

[tex]m = \frac{3.5\,mol}{2.5\,kg}[/tex]

[tex]m = 1.4\,\frac{mol}{kg}[/tex]

The molality of the solution is 1.4 moles per kilogram (molal).

Answer is: the current solution is unsaturated.

Unsaturated solution means that more of a substance can be dissolve.

For example:

Solubility of potassium chlorate (KClO₃) at 100 grams of water at 80°C is 37.5 g, that means that all 37.5 g is completely dissolves, this is the saturated solution.

If we add 20 grams of potassium chlorate in 100 grams of water, there is less solute than the saturated solution, so this is unsaturated solution.

Anions are the name for ions that have a negative charge. The body contains several common chemicals as ions. Sodium, potassium, calcium, chloride, and bicarbonate are typical examples.

Negatively charged electrons are called anion. When non-metals gain electrons, they are produced. They absorb one or more electrons. They have a negative charge overall as a result. The ion concentration iodide ( I- ), chloride ( Cl- ), and hydroxide are among examples ( OH– ).

The electrode where reduction takes place in any electrochemical cell  is characterized as the cathode. On the other extreme, the positive electrode will draw anions, or negative ions, to itself.

Thus, when an atom obtains electrons, it transforms into the negatively-charged ion known as an anion.

Answer:

b. lemon juice pH=2

Explanation:

Explanation:

Mass ratio C : H : N = 27.3 : 9.10 : 63.6

Mole ratio C : H : N = 27.3/12: 9.10/1 : 63.6/14

( Divide the mass ratio by their molar masses to find the ratio between moles)

Mole ratio = 2.275 : 9.10 : 4.54

= 2.275/2.275 : 9.10/2.275 : 4.54/2.275

= 1 : 4 : 2

Answer is CH4N2

The empirical formula of a compound is [tex]CH_4N_2[/tex]

The empirical formula of a chemical compound is defined as the simplest whole number ratio of the atoms present in a compound.

The empirical formula of a compound defines the simplest ratio of the number of different atoms present. The molecular formula gives the actual number of each different atom present in a molecule. The molecular formula is mainly used which is a multiple of the empirical formula.

Molecular Formula  = n × Empirical Formula

For above given example,

Mass ratio C : H : N = 27.3 : 9.10 : 63.6

Mole ratio C : H : N = 27.3/12: 9.10/1 : 63.6/14

( We divide the mass ratio by their molar masses to find the ratio between moles)

Mole ratio = 2.275 : 9.10 : 4.54 = 2.275/2.275 : 9.10/2.275 : 4.54/2.275

= 1 : 4 : 2

Thus, the empirical formula of a compound is [tex]CH_4N_2[/tex]

Answer:

solution is equal distribution of a solute and liquid

Explanation:

for example water and sugar make a solution

Solutions with a uniform composition are homogeneous solutions. A homogeneous solution, then, has an equal concentration of the constituent substances throughout the entire solution.

Similar to how water molecules are evenly distributed among the Na+ and Cl- ions when sodium chloride dissolves in it. The mixture's composition is constant throughout, and it is difficult to separate the components from one another. Solutions are homogeneous mixtures, which can contain substances in either state (solid, liquid, or gas).

Even if the components were evenly dispersed, they could still be separated at some point in a homogeneous mixture. The components may need to be separated using a procedure like evaporation, distillation, or chromatography, but this is still possible.
