What is stoichometry?
- Calculation of reactants in a chemical reaction
- Calculation of reactants and product in chemical reaction
- Calculation of products in a chemical reaction
- Non of the above
Correct Answer

A. Calculation of reactants and product in chemical reaction

Explanation

Stoichiometry is the calculation of the quantities of reactants and products involved in a chemical reaction. It involves using balanced chemical equations to determine the ratios of substances involved in the reaction. By using stoichiometry, one can calculate the amount of reactants needed or the amount of products that will be formed in a chemical reaction.

3.

Which law is stoichometry based on?
- Law of conservation of mass
- Law of dynamics
- Law of thermodynamics
- Law of density
Correct Answer

A. Law of conservation of mass

Explanation

Stoichiometry is based on the Law of Conservation of Mass, which states that in a chemical reaction, matter is neither created nor destroyed. This law is fundamental to stoichiometry as it allows for the balancing of chemical equations and the calculation of the quantities of reactants and products involved in a reaction. By applying this law, one can determine the ratios of substances in a reaction and make predictions about the amounts of products that will be formed.

Which of the following correctly represent the chemical formula for copper (11) nitrate.
- Cu2No2
- Cu(NO3)2
- CuNO3
- CU2NO3
Correct Answer

A. Cu(NO3)2

Explanation

The correct chemical formula for copper (II) nitrate is Cu(NO3)2. This formula indicates that there are two nitrate ions (NO3-) for every one copper ion (Cu2+), resulting in a balanced compound. The formula Cu2No2 is incorrect because it does not properly represent the charges of the ions. CuNO3 is also incorrect because it does not indicate the correct number of nitrate ions. CU2NO3 is incorrect because it uses an incorrect capitalization for the element symbol and does not represent the charges of the ions correctly.

What is the measure of quantity of matter ?
- Density
- Kilogram
- Volume
- Mass
Correct Answer

A. Mass

Explanation

Mass is the measure of the quantity of matter in an object. It represents the amount of material present in an object and is often measured in kilograms. Mass is different from weight, as weight is the force exerted on an object due to gravity. Mass remains constant regardless of the location, while weight can vary depending on the gravitational pull. Therefore, mass is the correct answer to the question.

Which of the following is not a type of stoichometry?
- Gas
- Composition
- Dynamic
- Non of the above
Correct Answer

A. Dynamic

Explanation

The term "stoichiometry" refers to the calculation of the quantities of substances involved in chemical reactions. It involves determining the ratios of reactants and products in a chemical equation. Gas stoichiometry deals with the calculations involving gases, composition stoichiometry focuses on the composition of compounds, and dynamic stoichiometry is not a recognized type. Therefore, "Dynamic" is not a type of stoichiometry.

What is the product of the following reaction? CH4+2O2
- CO2+H2O
- CO+2H2O
- 2CO2+H2O
- CO2+2H2O
Correct Answer

A. CO2+2H2O

Explanation

The given reaction is the combustion of methane (CH4) with oxygen (O2). This reaction produces carbon dioxide (CO2) and water (H2O). Therefore, the correct answer is CO2+2H2O, which represents the product of the reaction.

When was the term stoichometry first used?
- 1792
- 1793
- 1794
- 1795
Correct Answer

A. 1792

Explanation

The term stoichiometry was first used in 1792.

Rate this question:

Who first use the term stoichometry?
- Charles darwin
- Gay lussac
- Jermias Benjamin
- Boyles Lewis
Correct Answer

A. Jermias Benjamin

Which family is an element in Grouo 16,period 4 found?
- Hallogen family
- Metal family
- Oxide family
- Radon family
Correct Answer

A. Radon family

Explanation

The correct answer is Radon family. In the periodic table, Group 16 is known as the Chalcogens or Oxygen family. This group consists of elements such as oxygen, sulfur, selenium, and tellurium. However, Radon, which is a noble gas, is also located in Group 16. While noble gases are typically not considered part of a specific family, in this case, Radon is an exception and can be considered as a member of the Radon family.
