# Cliche worksheet #1 writing and balancing formula equations answers

Calculate the number of molecules of CO2 produced by the reaction of 2. STP is standard temperature and pressure, which is, 0oC and Kpa. To calculate the molar mass, divide the number of litres by the number of moles. Add about 10 mL of concentrated HCl to a gas collecting tube. Name the compound NO2. Since there is only one nitrogen atom AND it is the first element the prefix mono is not used. Add the ide ending to get oxide. There are two oxygen atoms so we also add the prefix di to get dioxide. Name the compound N2O.

Since there are two nitrogen atoms we need to add the prefix di to get dinitrogen. There is only one oxygen atom we add the prefix mono mono IS used for the second element to get monoxide.

Write the formula for carbon tetrachloride. There is no prefix before carbon in the chemical name, therefore, there is only 1 C atom in the chemical formula.

Chloride is derived from chlorine, whose symbol is Cl. Thus, there are 4 Cl atoms in the chemical formula. Write the formula for dinotrogen pentaoxide. Thus there are 2 N atoms in the chemical formula. Thus, there are 5 O atoms in the chemical formula. The advantage to using the new system is that you have one less system to learn.

Rules for naming Type III binary compounds: The cation is always named first and the anion second. A simple cation obtained from a single atom takes its name from the name of the element. Include a Roman numeral to indicate the oxidation number charge on the metal cation.

Write the name for the compound by combining the names of the ions. The Roman numeral is IV. The Roman numeral is I.

Write the formula for carbon IV chloride. The charge on chlorine is Write the formula for nitrogen V oxide. The charge on oxygen is Therefore, we need 2 N atoms and 5 O atoms to balance the charges.Chemistry - how to write balanced ionic equations, Molecular, Complete Ionic, and Net Ionic Equations, examples and step by step solutions, How to write ionic and net ionic equations, How to write a double replacement net ionic equation, what are spectator ions, precipitation reaction, single displacement reaction.

Equations involving unknown variables are solved by balancing the left member and the right member. For example, in the equation y + 5 = 12, I know that the left member must equal 12 for it to balance with the right member.
