Q.3: What is the difference between chemical and molecular formulas?A: The chemical formula represents the formula of ionic compounds, whereas the molecules formula represents the formula of covalent compounds. For example- Table salt has a chemical formula because it is made up of Na+ and Cl...

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)?
and water and carbon dioxide are two products of a reaction, then it is probably a combustion reaction. Double-displacement reactions tend to involve ionic solutions that produce ionic compounds, one of which forms a precipitate; if you notice a precipitate in your reaction, you know it can li...
They either form covalent bonds, in which the atoms join by sharing electrons with each other, or ionic bonds, in which neutrally charged atoms lose electrons, and bond with other atoms to restore balance. The noble gases are outliers because their atoms already have the maximum number of ...

We may choose a symplectic basis of internal three- forms A to write VA(z) in the form (3.27) and identify the superconformal chiral fields za with the standard projective coordinates for the complex structure moduli [19]. We may then go to the Einstein frame as described in section 3.1,...
