Of the statements in Exercise 10, which are quantitative? Which statement best describes why life on earth is carbon based? What property of carbon most contributes to its ability to form such a diverse range of molecules? Which statement describes a chemical property of silicon 3. As the matter in the match burns, its chemical composition changes, and new forms of matter with new physical properties are created. These are just a few examples of how chemistry impacts your everyday life. Q: 2) Identify each of the following as an element, compound, or mixture.
Q: Identify each of the following as a physical or chemical change:a. Apples turn brown after…. Q: Fact, Law, Hypothesis, or Theory? A: Since you have posted a question with multiple subparts, we will solve first three subparts for you. Which statement describes a chemical property of silicon oxide. There is an additional phrase in our definition of science: "the natural universe. " Examples of compounds include water, penicillin, and sodium chloride (the chemical name for common table salt). Most people have a morning ritual, a process that they go through every morning to get ready for the day. Is a combination of more than one element. English is certainly worth knowing (at least for people in predominantly English-speaking countries), but why isn't it science? A: As you have posted multiple independent questions in a single request we will solve the first…. Q: Determine whether each of the following represents a physical property or a chemical property: (a)….
Normally, this would indicate that carbon forms two bonds, since only two of the electrons are in orbitals that are not already paired. Are tests of the natural universe to see if a guess (hypothesis) is correct. The carbon dioxide produced by the yeast dissolves in the wine. An element is a fundamental chemical part of a substance; there are about 115 known elements.
Our experts can answer your tough homework and study a question Ask a question. It has four valance electrons. Metals are typically shiny, conduct electricity and heat well, and are malleable and ductile; nonmetals are a variety of colors and phases, are brittle in the solid phase, and do not conduct heat or electricity well. Which statement describes a chemical property of silicon nitride. Carbon, however, is able to form hybrid orbitals by combining the three p orbitals and one s orbital to form four identical sp3 orbitals, each containing one electron.
D- It reacts with hydrogen to form a gas. Example Question #5: Understanding Essential Properties Of Carbon. Nonmetals also exist in a variety of phases and colors at room temperature. The relative ratio of other elements to carbon. Explain your answer. Which statement describes a chemical property ? a- Its crystals are a metallic gray. b- It dissolves in alcohol. c- It forms a violet-colored gas. d- It reacts with hydrogen to form a gas. | Homework.Study.com. In Exercise 10, which choices are also solutions? On the other hand, the chemical property is measured or observed once a chemical transformation has taken place. Some sparkling wines (including champagne) are made by sealing a bottle of wine with some yeast in it. Which of these statements are qualitative descriptions? If matter always stayed the same, chemistry would be rather boring. Because of its ability to hybridize orbitals, carbon can also bond to three substituents by forming a double bond, or to two substituents via two double bonds or the combination of a single bond and a triple bond.
Most experiments include observations of small, well-defined parts of the natural universe designed to see results of the experiments. For example, air is matter, but because it is so thin compared to other matter (e. g., a book, a computer, food, and dirt), we sometimes forget that air has mass and takes up space. All scientific fields use mathematics to express themselves—some more than others. The field of science has gotten so big that it is common to separate it into more specific fields. It has a small atomic mass. Name an example of a field that is not considered a science. Finally, understand that science can be either qualitative or quantitative.
When you open a container of soda or beer, you hear a distinctive hiss as the excess carbon dioxide gas escapes. Carbon has four valance electrons, allowing it to form a wide range of bonds with other atoms. Carbon is incapable of forming a quadruple bond, and it is not magnetic. Are the following combinations homogeneous mixtures or heterogeneous mixtures? Properties of Matter: A property of matter can be identified as either a chemical property or a physical property. Q: Which of the following statements describe chemical property?
Answer and Explanation: 1. Find answers to questions asked by students like you. Quantitative expressions are very important in science; they are also very important in chemistry. There are many statements referred to as "the theory of _______" or the "______ theory" in science (where the blanks represent a word or concept). Carbon is phenomenally important to life as we understand it. Science deals only with what occurs naturally.
