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 ...
and it's passion that stems from finding the other person attractive. Sexual chemistry is influenced in large part by pheromones, chemical signals present throughout the animal world that communicate between two members of a species. Bronstein says physical chemistry is, "either not there...
In chemistry, the concentration of any species is denoted by writing it in square brackets. For example, [X] means “the concentration of X.” Given the above definition of pH, the fact that a proton is simply a hydrogen atom that has lost its only electron (H+), and using the squa...
What is the pH of a 0.1 m basic solution? What is pH value in chemistry? What does the pH of a solution represent? What is the pH of 2.3 \times 10^{-4}? How does one calculate the ph of a solution? Calculate the pH of a solution for which H+ = 1.0 x 10-3 M. ...
If she were accepted, she would major in chemistry. He’ll join the band on the condition that he be the backup singer. Subjunctive sentences with multiple clauses Sentences in the subjunctive mood also often, but not always, contain two or more clauses. A clause is a group of words tha...
Inorganic chemistrystudies the chemical compounds in inorganic, or non-living things such as minerals and metals. Traditionally, inorganic chemistry considers compounds that donotcontain carbon (which are covered by organic chemistry), but this definition is not completely accurate, according to theACS....
If you look 'chemistry' up in Webster's Dictionary, you'll see the following definition: "chem·is·try n., pl. -tries . 1. the science that systematically studies the composition, properties, and activity of organic and inorganic substances and various elementary forms of matter ...
pH measurement is an important parameter in nearly every water quality application. In environmental sampling and monitoring, high or low pH values can be indicative of pollution. To determine the pH of water, a pH meter can be used to measure this impor
What does a neutral pH of 7 actually represent? What does pH stand for in chemistry? What is the strongest acid on the pH scale? What are the pH ranges for acids and bases? What is the pH level of sodium bicarbonate? What is the pH of distilled water?
The pH scale is a log scale The scientific definition of pH is: pH = -log10[H+] What these symbols mean: [H+] stands for the concentration of H+ions in the substance in moles per litre (the standard unit for concentration used in chemistry) ...
