It is a compound that is made up of one sodium atom and one chlorine atom. It also has a uniform structure. What is a pure substance in chemistry? A pure substance is made up of one type of element or one type of compound. These substances also have a uniform structure to them with...
The pH scale runs from 0-14. Matter with a pH of 7, like pure water is considered to be neutral. Anything that has a pH of 0 up to 7 is acidic and anything above 7 and up to 14 is basic. Stomach acid is a strong acid at a pH of about 2. Soaps and detergents are more bas...
Question:A solution of 10.0 g of a nonvolatile, non-dissociating compound dissolved in 0.200 kg of benzene boils at 81.2 °C. Calculate the molecular weight of the compound. Ebullioscopic constant for benzene: 2.53 °C/m and Boiling Point of pure benzene: 80.1°C Options: (a) 115 gm/mo...
It is easiest to leave elements found in pure form for last. Step 5: Check the equation once more and ensure the charge and the number of elements on both sides of the equation are balanced. Example Hydrogen (H2) and oxygen (O2) combine to produce water (H2O). H2 + O2→ H2O This ...
In chemistry, a pure substance is a sample of matter with both definite and constant composition and distinct chemical properties.
Atom Definition Chemistry The smallest particle of an element, which may or may not have an independent existence but always takes place in a chemical reaction is called an atom. An atom is defined as the smallest unit that retains the properties of an element. An atom is composed of sub-...
mixtures mixtures in chemistry, a mixture is a compound made up of two or more chemical components that are not chemically linked. a mixture is a physical blend of two or more substances that preserve their identities and are blended in the form of solutions, suspensions, or colloids. table ...
In the case of two fluorine atoms, which both have an electronegativity of 4.0, the electrons are equally shared, leading to a pure covalent bond. Then we have polar covalent bonds (partial sharing) for differences between 0.5 to 2.0. As an example, in a carbon and fluorine bond, w...
