A chemical reaction is a process that changes some chemical substances into others. What is involved in the process of forming these new chemical substances?

Elements consist of one type of atom. They cannot be broken down chemically into simpler substances. Hydrogen is an element. Other examples are the noble gasses, the transition elements, and...

Since 8x3=24 and since 12x3=36 you need to add 6oz of chemical B to have 24oz of chemical A and 36oz of chemical B. Take 1/3 of the total mixture...

A chemical bond is typically described as the superposition of 2 electrons, which form a region of HIGH electron density between neighbouring nuclei. Because atomic nuclei are strongly positively charged,...

Chemical change because you are changing the identity of the substance, hence the forming of different bonds .

...i.e.. solid to liquid, liquid to gas...and vice versa. And certainly, , mass per unit volume, changes markedly upon a phase change between a condensed phase, solid or liquid, and...

Chemical change is characterized by the making and breaking of strong chemical bonds, and the formation of new substances. Clearly, during the fermentation, sugars reacted chemically to give carbon dioxide...

Now, of course, as chemists we deal with molar quantities, and the oxidation reaction must involve a series of complex elementary steps, but here the molecule is simply represented as...

Based on the information I got from you: $m_"Zn" = "6.530 g"$ $m_("CuSO"_4cdot5"H"_2"O") = "5.00 g"$ (in lab you tend to be handed the hydrate) From the molar...

Because as substances change from liquid to solid they lose kinetic energy the substances usually lose volume and become more dense. Water in contrast forms a hexagonal crystal that has...

We usually use $"HIn"$ to represent a weak acid, which, as its name suggests, does not ionize completely in aqueous solution, that acts as a $"pH"$ indicator. $"HIn"_ ((aq))...
