what do members of the chemical manufacturers association pledge in the responsible care program?

Responsible Care® is a voluntary commitment by the global chemical industry to drive continuous improvement and achieve excellence in environmental, health and safety and security performance.

What is microscopic and macroscopic domain?

Explanation: Macroscopic domain: The macroscopic domain includes the study of the phenomenon involving objects of finite size on terrestrial scale and even on astronomical scale. Microscopic domain: The microscope domain includes the study of phenomenon involving molecules,atoms,nuclei,and other elementry particles.

What are macroscopic properties chemistry?

Hint: Macroscopic properties are those properties associated with a macroscopic system – a system consisting of a large number of molecules, atoms or ions. … The properties associated with a macroscopic system includes – pressure, temperature, density, volume, viscosity, resistance, surface tension of liquid etc.

What are the three different levels at which chemists look at materials How do they differ from one another?

How do they differ from one another? Symbolic, Macroscopic, and Microscopic. Symbolic relates the links between compounds, macroscopic looks at chemical changes and reactions at the macroscopic level, and microscopic looks at the chemical changes at atomic levels. You just studied 84 terms!

What are some of the clues that help us determine whether in observe changes physical chemical?

Some clues that help us determine whether an observed change is physical or chemical are: In physical change, you will be able to restore it to its original condition/substance, such as ice melting into water; … Because melted gold is still gold but in a different form, this change is a physical change.

What clues help us to determine whether an observed change is physical or chemical?

Yes; new substances formed, as evidenced by the color changes and bubbles. Some signs of a chemical change are a change in color and the formation of bubbles. The five conditions of chemical change: color change, formation of a precipitate, formation of a gas, odor change, temperature change.

Basic knowledge of chemistry helps you to read and understand product labels. Chemistry can help you make informed decisions. … Chemistry teaches useful skills. Because it is a science, learning chemistry means learning how to be objective and how to reason and solve problems.

What is chemical classification of matter?

Matter can be broken down into two categories: pure substances and mixtures. Pure substances are further broken down into elements and compounds. … A chemical substance is composed of one type of atom or molecule. A mixture is composed of different types of atoms or molecules that are not chemically bonded.

Which of the following is an example of a chemical change?

Burning, cooking, rusting and rotting are examples of chemical changes.

How is matter classified according to their chemical composition?

Matter can be classified into two broad categories: pure substances and mixtures. … A material composed of two or more substances is a mixture. Elements and compounds are both examples of pure substances. A substance that cannot be broken down into chemically simpler components is an element.

How do molecules depend on atoms?

When atoms combine by forming covalent bonds, the resulting collection of atoms is called a molecule. We can therefore say that a molecule is the simplest unit of a covalent compound.

How do atoms relate to molecules?

Atoms can bond together into groups and form a molecule. If the molecule contains atoms of different types bonded together, we call it a compound. For example, two hydrogen atoms and one oxygen atom bonded together creates the compound water. … No bonding or chemical reactions are involved in creating a mixture.

Why do atoms come together to create molecules?

Atoms come together to form molecules because of their electrons. … When two atoms share electrons between them, they are locked together (bonded) by that sharing. These are called covalent bonds. Bonds like this are in oxygen gas, nitrogen gas, and hydrogen gas.

What is the Responsible Care program?

Responsible Care® Responsible Care® is the global chemical industry’s voluntary initiative to drive continuous improvement in safe chemicals management and achieve excellence in environmental, health, safety and security performance.

Should manufacturers be responsible for the effects of the chemicals used in the creation of their products?

Companies and governments must take responsibility for chemicals in use. The company that sells or uses the chemical should be responsible for making it safe for workers and consumers.

What are the responsibilities associated with the chemical industries?

The responsibilities of the chemical industry involves in the offering of the preventive measures to the employees from being captured with hazardous substance, offering the chemicals to other factories in the production of the products, and meeting the needs of the clients.

What do you mean by macroscopic?

Definition of macroscopic

1 : observable by the naked eye. 2 : involving large units or elements. Other Words from macroscopic Example Sentences Learn More About macroscopic.

What is the difference between macroscopic and mesoscopic?

A first difference is that the macroscopic object can be well described by the average properties of the material from which it is made. The mesoscopic object, in contrast, is so small that fluctuations around the average become important.

What is meant by macroscopic domain?

Macroscopic domain includes phenomena at large scales like laboratory, terrestrial and astronomical. It includes following subjects: Mechanics – It is based on Newton’s laws on motion and the laws of gravitation.

What are some examples of macroscopic?

Examples of familiar macroscopic objects include systems such as the air in your room, a glass of water, a coin, and a rubber band—examples of a gas, liquid, solid, and polymer, respectively. Less familiar macroscopic systems include superconductors, cell membranes, the brain, the stock market, and neutron stars.

What are microscopic and macroscopic properties?

Microscopic properties refer to properties of atoms while macroscopic properties refer to properties of molecules. At each scale-size, the properties are further classified in terms of single atoms/molecules or multiple atoms/molecules of different types.

What are the macroscopic and microscopic differences between physical and chemical changes?

In the context of Chemistry, “microscopic” implies the atomic or subatomic levels which cannot be seen directly (even with a microscope!) whereas “macroscopic” implies things that we can know by direct observations of physical properties such as mass, volume, etc.

What is chemistry and branches of chemistry?

The five primary branches of chemistry are physical chemistry, organic chemistry, inorganic chemistry, analytical chemistry, and biochemistry.

Why are there different branches of chemistry?

All Kinds of Chemistry

Scientists can use chemistry to study living things, medicine, the environment, food, and more. Due to this large variety, there are different branches of chemistry which use chemistry to study specific things.

What is chemistry and types of chemistry?

Fundamentally, chemistry is the study of matter and change. The way that chemists study matter and change and the types of systems that are studied varies dramatically. Traditionally, chemistry has been broken into five main subdisciplines: Organic, Analytical, Physical, Inorganic and Biochemistry.

How does knowing the reactants and help you classify a chemical reaction?

How does knowing the reactants and products help you classify a chemical reaction? … The reactants and products determine the type of chemical reaction. If there are more products than reactants, then it is a decomposition reaction. If there are more reactants than products, it is a synthesis reaction.

Which of the following observations can be used to determine whether a chemical reaction has taken place?

Following are the observations to determine whether the chemical reaction has taken place or not: Change in colou. Evolution of gas. Changee in temperature.

What information does a chemical equation provide?

A chemical equation is an expression of the net composition change associated with a chemical reaction. It shows how a certain amount of reactants yields a certain amount of products. Both of these amounts are measured in moles.
