This week, a compound of many names. Brian Clegg explains more. Brian Clegg © Shutterstock As is often the case with a compound that has long been in use, calcium hydroxide is rich in alternative names. Its best known common description, slaked lime, suggests that it is lime (more properly known as calcium oxide) that has drunk its fill. ‘Milk of lime’ refers to its state before…

Your reaction will produce 0.624 g of hydrogen gas. Start by writing the balanced chemical equation for this reaction #Ca_((s)) + 2H_2O_((l)) -> Ca(OH)_text(2(s]) + H_text(2(g]) uarr# Notice that you have a #1:1#mole ratio between calcium and hydrogen gas. This tells you that, regardless of how many moles of calcium react, you produce an equal number of moles of hydrogen…

Oxidative phosphorylation is a metabolic pathway that uses energy released by the oxidation of nutrients to produce adenosine triphosphate (ATP). Although the many forms of life on Earth utilize a range of different nutrients, almost all carry out oxidative phosphorylation to produce ATP, the molecule that supplies energy to metabolism. This pathway is probably so pervasive…

The oxidation state is a way to determine the number of electrons being added or removed from an atom. When electrons are removed, creating a positive atom, then the atom has been oxidized. If electrons are added, making a negative atom, then the atom has gone through reduction. There are several rules which are used as a standard to determine the oxidation state of an atom…
