How do you use H20 in a sentence?
H2O is the formula for water.
What is the chemical symbol for heated water?
All forms of water are shown as H2O. To show the different states use (g) for gas, (s) for solid, and (l) for liquids. To show added heat, you can use the triangle or "delta" symbol. Just like when writing a balanced chemical equation.
What do you use to balance charges when writing a molecule's formula?
Because the chemical formula of the molecule must be neutral.
How do you calculate the formula of hydrated Barium Chloride given that a sample of 10g of BaCl2.nH2O crystals lost 1.475g of of water on heating?
Mass of BaCl2 = crucible + lid + BaCl2.nH2O - empty crucible + lidMass of water contained in hydrated BaCl2: Initial mass - final massNo. of moles of H2O in hydrated salt = No. of moles = mass of H2O/formula mass of H2O Use this answer in ratioNo. of moles of BaCl2 in 3.399 g = No. of moles = mass of BaCl2/formula mass of BaCl2 Use this answer in ratioThe ratio of BaCl2 to H2O is 1 : 2
What is the shorthand way of representing chemical compounds?
Of any compound? There are millions!H20 - waterNaCl - saltCO2 - carbon dioxideSO2- sulphur dioxideCuS04 - copper sulphate
When to use subscripts when writing a formula?
Do you mean subscripts like H2O (ie the 2 would be subscripted)?

What do you use to balance charges when writing a molecule's formula?
Because the chemical formula of the molecule must be neutral.
What are the 3 steps in writing chemical equation?
A. Learn the correct symbols for the elements. (this is similar to reciting the alphabet... a, b, c..., as well as identifying the symoblos we use or each letter.)B. Learn the names and formulas of seven(7) acids and ammonia. The acids and their formulas along with ammonia and its formula are:C. Learn the meaning of several important prefixes and sufixes as they relate to the formula of polyatomic ions, caution charges, and anions.D. Learn the name of the prefixes that are used to denote one(1) through ten(10) atoms in a formula.
What types of compounds use prefixes in the names?
Covalent compounds, particularly binary compounds consisting of two nonmetals, use prefixes in their names to indicate the number of atoms of each element present in the molecule. This helps distinguish between similar compounds with different ratios of atoms.
Why do you use prefixes?
Prefixes are used in language to modify the meaning of a word. By attaching a prefix to a root word, we can create new words with different meanings. This allows us to be more specific in our communication and convey nuanced information.

What is an example of a subscription?
Subscripts are most familiar to use in the writing of chemical formulas such as H2O -- the 2 should be a subscript -- and in mathematics you will see variables with subscripts.
