The oxidation number of an element is the charge the element would have if the compound that it is a part of consisted only of ions. When the oxidation number of an element increases, it is said to undergo oxidation. When the oxidation number decreases, t...
What is the molar mass of Na2SO4? What is the molar mass of copper(II) sulfate, cuso4? What is the molar mass of Fe(NO3)2*9H20 What is the molar mass of Fe(NO3)2? What is the weight in grams of 1 mole of ammonium sulfate (NH4)2SO4? What is the relative formula mass of ...
It is a branch of natural science that examines the building blocks of matter, including the atoms, molecules, and ions that make up compounds and their composition, structure, behaviour, and changes that occur when they interact with other things. The quantum mechanical approach is currently used...
Exact mass can be defined as the average mass of the atoms of an element measured in an atomic mass unit. It is also known as weight average molecular weight. Weight average molecular weight is the weight fraction of molecules in a polymer sample. It is another way of determining themolecul...

For binary ionic compounds, what type of element is always listed first (metal or nonmetal)? Which of the following substances will form a metallic solid? SiC CO_2 KCl Ti Which are the ionic compounds? a) N2O b) NaCl c) BaBr2 d) SiO2 e) AlF3 ...
What kind of reaction is this? {eq}Fe(s) + CuSO_4(aq) \to Fe_2(SO_4)_3(aq) + Cu(s) {/eq} Chemical Reactions: The process of chemical reaction is crucial in the formation of new substances. It is a consequence of the rearrangement of a element or compou...
This is done by adding coefficients to each substance so the number of each element in the equation is equal on both sides. Net Ionic Equation: The net ionic equation is a chemical equation which represents the changes in the substances in an ionic reaction witho...
What is definition of element? When do you use each of the following equations? a. q = mc^{t} b. q = mHf c. q = mHv What does the term chemical shift mean? What is the best definition of a precipitation reaction? What does the term mixture mean in chemistry?
Is sodium chloride classified as an element, a compound, or a mixture? Explain. What are the different physical properties between HCl and NaCl? Explain the causes of their differences. What happens when H3PO4 is heated with zinc and HCl?
