Matter is made up of elements and all of the elements that exist are listed on the periodic table. Each element has its own symbol.Answer and Explanation: A chemical equation means a combination of substances reacts to form a new set of substances. ...
when it is added in a solution of Copper Chloride, it replaces Copper and forms Zinc Chloride. Copper is given out in the ionic form. This reaction is also an excellent example ofcationic replacement. We say this because the replacing ion has a positive charge, i.e., 2+....

The atomic number is the only number important to identifying a proper symbol for an element on the periodic table. Answer and Explanation: We identify elements by the proton number. For the notation {eq}\rm X^a_b {/eq}, element {eq}\rm X...
Cu(s) + 2 Ag+(aq) → Cu2+(aq) + 2 Ag(s) Another example of oxidation where an element combines with oxygen is the reaction between magnesium metal and oxygen to form magnesium oxide. Many metals oxidize, so it's useful to recognize the form of the equation: ...
What is an element in the third period (row) of the periodic table with four 3p electrons? Can you explain the factors that can alter the purity of substances in the identification of halides? Describe the effect of pH and temperature on enzyme functioning. What is lactic acid? What are ...

Here, S is a solvent molecule, such as water or dimethyl sulfoxide (DMSO). For example, here is the dissociation of hydrochloric acid in water: HCl(aq) → H+(aq) + Cl-(aq) A strong acid hasa pKa valueless than -2. The pKa value of the acid depends on the solvent. For example,...
2 K(s) + 2 H2O(l) → 2 KOH (aq) + H2(g) All elements in a particular group react in an analogous manner. How Do Alkali Metals React Otherwise? As alkali metals are the most reactive group of metals in the periodic table, each of these metals is capable of reacting with different...
In so doing, the nucleophile is considerably less reactive; everywhere it goes, its lone pairs of electrons are interacting with the electron-poor hydrogen atoms of the solvent. The ability of nucleophiles to participate in hydrogen bonding decreases as we go down the periodic table. Hence fluorid...
