Describe all the types of chemical reactions with example.​

Answers

Answer 1
Redox is a type of chemical reaction in which the oxidation states of atoms are changed. Redox reactions are characterized by the actual or formal transfer of electrons between chemical species, most often with one species undergoing oxidation while another species undergoes reduction. The chemical species from which the electron is removed is said to have been oxidized, while the chemical species to which the electron is added is said to have been reduced.
Transcription is the process of copying a segment of DNA into RNA. The segments of DNA transcribed into RNA molecules that can encode proteins are said to produce messenger RNA. Other segments of DNA are copied into RNA molecules called non-coding RNAS. Averaged over multiple cell types in a given tissue, the quantity of MRNA is more than 10 times the quantity of ncRNA.
Chelation is a type of bonding of ions and molecules to metal ions. It involves the formation or presence of two or more separate coordinate bonds between a polydentate ligand and a single central atom. These ligands are called chelants, chelators, chelating agents, or sequestering agents. They are usually organic compounds, but this is not a necessity, as in the case of zinc and its use as a maintenance therapy to prevent the absorption of copper in people
Catalysis is the process of increasing the rate of a chemical reaction by adding a substance known as a catalyst. Catalysts are not consumed in the reaction and remain unchanged after it. Often only very small amounts of catalyst are required. Catalysts generally react with one or more reactants to form intermediates that subsequently give the final reaction product, in the process regenerating the catalyst.

2. 10.00 grams of a sample of hydrated PtCl4 are heated and lose 3.00 g of water. How many moles of water are combined with each mole of PtCl4?

Answers

Answer:

8 mol

Explanation:

Step 1: Calculate the mass of PtCl₄ in the sample

10.00 grams of a sample of hydrated PtCl₄ are heated and lose 3.00 g of water. The mass of PtCl₄ is:

mPtCl₄ = 10.00 g - 3.00 g = 7.00 g

Step 2: Calculate the moles corresponding to 7.00 g of PtCl₄ and 3.00 g of H₂O

The molar mass of PtCl₄ is 336.9 g/mol.

7.00 g × 1 mol/336.9 g = 0.0208 mol

The molar mass of H₂O is 18.02 g/mol.

3.00 g × 1 mol/18.02 g = 0.166 mol

The molar ratio of H₂O to PtCl₄ is:

0.166 mol H₂O/0.0208 mol PtCl₄ ≈ 8 mol H₂O/ 1 mol PtCl₄

What eventually happens to all radioactive isotopes?
A. They become stable after one half-life.
B. They emit particles, electromagnetic radiation, or both.
C. They absorb energy when they decay.
D. They are pulled apart by strong nuclear forces.

Answers

Answer:

B. they emit particles electromagnetic radiation or both

Radioactive isotopes emit particles, electromagnetic radiation, or both. The correct option is B.

Radioactive decay occurs in all radioactive isotopes and involves the release of particles, electromagnetic radiation, or both.

Radioactive decay occurs owing to the instability of the isotope's atomic nucleus.

The nucleus releases surplus energy in the form of particles (such as alpha particles or beta particles) or electromagnetic radiation (such as gamma rays) in order to achieve a more stable state.

This random process continues until the radioactive isotope is converted into a stable isotope.

Thus, correct option is B.

6c.Calculate the maximum volume, in dm3, of chlorine gas at Stp that can be obtained from 23.4 tonnes of molten sodium chloride. 1 tonne= 10^6 Mr of NaCl=58.5 molar volume of chlorine at stp= 24dm3 Give your answer in standard format.

Answers

Answer:

4.48×10⁶ dm³

Explanation:

We'll begin by converting 23.4 tonnes to grams (g). This can be obtained as follow:

1 tonne = 10⁶ g

Therefore,

23.4 tonnes = 23.4 × 10⁶

23.4 tonnes = 2.34×10⁷ g

Thus, 23.4 tonnes is equivalent to 2.34×10⁷ g

Next, we shall determine the number of mole in 2.34×10⁷ g of NaCl. This can be obtained as follow:

Mass NaCl = 2.34×10⁷ g

Molar mass of NaCl = 58.5 g/mol

Mole of NaCl =?

Mole = mass / molar mass

Mole of NaCl = 2.34×10⁷ / 58.5

Mole of NaCl = 4×10⁵ moles

Next, we shall determine the number of mole of chlorine, Cl₂ produced from the reaction. This can be obtained as follow:

2NaCl —> 2Na + Cl₂

From the balanced equation above,

2 moles of NaCl reacted to produce 1 mole of Cl₂.

Therefore, 4×10⁵ moles of NaCl will react to produce = (4×10⁵ × 1)/2 = 2×10⁵ moles of Cl₂.

Thus, 2×10⁵ moles of Cl₂ were obtained from the reaction.

Finally, we shall determine the volume of Cl₂ produced. This can be obtained as follow:

1 mole of Cl₂ at stp = 22.4 dm³

Therefore,

2×10⁵ moles of Cl₂ at stp = 2×10⁵ 22.4

2×10⁵ moles of Cl₂ at stp = 4.48×10⁶ dm³

Thus, the volume of chlorine obtained from the reaction is 4.48×10⁶ dm³

A student conducts an experiment to determine how the temperature of water affects the time for sugar to dissolve. In each trial, the student uses a different amount of water and a different temperature of water. What is wrong with this experimental design? A.The student changed more than one independent variable. B.The student did not change enough independent variables. C.The student needs to perform more trials. D.The student does not have a dependent variable.

Answers

What is wrong with the experimental design is that the student changed more than one independent variable.

WHAT AN EXPERIMENT SHOULD CONTAIN?

An experiment is a procedural method of solving a scientific problem or answering a scientific question. An ideal experiment should contain two variables namely: independent variable and dependent variable.

Dependent variable: This is the variable that the experimenter measures in the experiment. The dependent variable responds to changes made to the independent variable.

Independent variable: This is the variable that is manipulated in an experiment in order to bring about a response.

In the experiment conducted by the student in this question in order to determine how the temperature of water affects the time for sugar to dissolve. The independent variable is the DIFFERENT TEMPERATURE OF WATER while the dependent variable is the TIME TAKEN FOR SUGAR TO DISSOLVE.

N.B: An experiment should have only one independent variable and all other variables should be kept constant. This is to have a reliable result.

However, this student used two independent variables (temperature and amount of water) for the experiment, which is wrong for the experimental design.

Therefore, the fact that the student changed more than one independent variable is wrong for the experimental design.

In ionic bonding Question 41 options: the electrons are shared between the atoms. the process of forming an ionic bond is highly endothermic overall. the bonding that occurs is usually between two nonmetal atoms. a noble gas configuration is formed for each element or ion. At least two of the above statements are correct.

Answers

Answer: In ionic bonding (a noble gas configuration is formed for each element or ion).

Explanation:

IONIC bonding, which is also called electrovalent bonding involves the complete transfer of electrons from one atom to another in order to attain a noble gas electron configuration.

The noble gases or group 0 elements have a completely filled outermost shell of eight electrons. This makes them generally very stable, that is, unreactive. There is a natural drive for other atoms to attain the electron configuration of group 0 (inert gases) elements. This usually results in atoms entering into chemical combinations by losing, gaining or sharing electrons.

Answer:

D: Atmospheric pressure is greater than vapor pressure,and water molecules escape from the solution into the air.

Atmospheric pressure is greater than vapor pressure, and water molecules escape from the solution into the air, which occurs during boiling. The correct option is D.

What is boiling?

Boiling is a process when more heat is given to any liquid, it starts to boil. When the temperature is increased, boiling happens, but only in liquid. The molecules of liquid start to turn into vapor and start to escape into the atmosphere.

It is also called the vaporization of the liquid. The boiling points of different liquids are different, and they start to boil at their own temperature.

Thus, the correct option is D. Water molecules escape from the solution into the air when atmospheric pressure exceeds vapor pressure.
