Explain how to write the formula for phosphorus tribromide. Molecular Formulae: To determine the chemical formular of a molecule or compound unit, we can use the valencies, especially for diatomic molecules. For neutral atoms of the elements with less than 4 valence electrons, the group numbe...
How to find the chemical formula of an ionic/covalent compound. Give explanation. What are the rules for combining two non-metals in a chemical reaction? How do the subscripts work when combined? Explain your answer. How do you write formulas for binary compounds (for example, CuCO3)?
Molecular Formula:Molecular formula and empirical formula are two significant aspects of chemistry. Both these phenomena contribute to helping students engage in different calculations and understand the subject better. It is one of the basic concepts of Chemistry and plays an important role in building...
The name of a compound usually gives you all the information you need to write its chemical formula. The first part of the name denotes the cation, or positively charged ion that forms the molecule, while the second part denotes the anion, or negative ion. A balanced chemical formula also ...
{eq}NO_{2}^{-} {/eq} can accept a hydrogen ion to become {eq}HNO_{2} {/eq}, so it is the conjugate base. Step 2: Write and balance the chemical reaction This time, since we are adding HCl, a strong acid, to the buffer solution, we write an equation for the reaction ...
Steps on How to Perform a Titration of Excess Weak Acid with a Strong Base Step 1: Write a balanced chemical equation for the acid-base reaction. Step 2: Create an Initial Change Equilibrium (ICE) Table and fill out the table with the stoichiometric quantities. Using the given...
