What is volumetric analysis in analytical chemistry? What volume (mL) of 1.50 10-2 M hydrochloric acid can be neutralized with 115 mL of 0.244 M sodium hydroxide? A substance has a density of 4.5 g/mL. What is this in kg/L?
Chemistry: Chemistry is the study of elements and compounds, and how they interact with each other. Concepts in chemistry can be applied to practically everything, from cooking to cleaning up environmental disasters. Answer and Explanation:
What is a Mixture ... in terms of Chemistry ? Matter can be classified in various ways according to its structure, behaviours and physical and chemical properties. The main classifications of matter include the categories element and compound, either of which may also be called a substance (...
There are many possible definitions ofmatter. In science, matter is the term for any type of material. Matter is anything that has mass and takes up space. At a minimum, matter requires at least one subatomic particle, although most matter consists of atoms. The wordmatteris sometimes used ...
In chemistry, “mM” stands for millimolar, which is a unit used to express a solute’s concentration in a solution. Explanation: Millimolar (mM) concentrations are often used for convenience when working with solutions of small quantities of substances. One millimolar (1 mM) is equal to one...
"Chemistry is energy," says relationship coach Jaime Bronstein. "It's an energetic connection you can feel." Some indicators of this connection are body language cues like butterflies in your stomach, a rapid heart rate, smiling and prolonged eye contact between the two of you. ...
