Mass numbers are used to identify different isotopes of an element and are a count of the protons and neutrons found in that isotope's nucleus. Interestingly, the number of protons will remain constant, regardless of the isotope, but the number of neutrons will change. This is because an ato...
In chemistry, if the total number of moles of a chemical substance is available, then the mass of the chemical substance can easily be obtained by taking the product of the molar mass and number of moles of the substance. In the usual measuring unit, the mass is shown by...
The question asks for the mass of the potassium nitrate precipitate, but potassium nitrate does NOT form a precipitate. You probably mean to ask for the mass of the copper(II) hydroxide precipitate.First, write a balanced equation:2KOH(aq) + Cu(NO3...
Finally, we present the promises and challenges that arise when seeking to incorporate microbiome data in dietary planning and portray the anticipated revolution that the field of nutrition is facing upon adopting these novel concepts. Key points Common multifactorial diseases in both industrialized and ...
There are over three million known compounds,with no end in sight as to the number that can and will be prepared in the future.Each compound is unique and has characteristic physical and chemical properties.Let us consider in some detail two compounds——water and mercuric oxide.Water is a ...
Rubidium is the chemical element with the symbol Rb and atomic number 37. Rubidium is a very soft, silvery-white metal in the alkali metal group. Rubidium metal shares similarities to potassium metal and caesium metal in physical appearance, softness and conductivity. ...
Epigenetic memory is defined as the maintenance of gene expression states through cell generations in the absence of the initiating signals. PREs were first discovered in flies, in which they can mediate epigenetic memory of both silent and active states of their associated genes. Epigenetic memory ...
of the sodium-potassium ATPase pump, also identified through compound library screening as a small molecule HIF-1 inhibitor60, has been reported to prevent diet-induced obesity in mice, although the suggested mechanism is through inhibition of the IL-17A phosphorylation of PPARγ in adipocytes61. ...
Visceral leishmaniasis (VL) is a systemic protozoan disease that is transmitted by phlebotomine sandflies. Poor and neglected populations in East Africa and the Indian sub-continent are particularly affected. Early and accurate diagnosis and treatment re
We are embedded in a community where reciprocity is a way of life and ‘favours’ are remembered rather than recorded on a balance sheet. So what should I say to the 31% of Australians who, like the young-would-be farmer, lwho still have to pay the rent, or to the vanishingly small...
