What is the chemical formula for the blue disulfur trioxide?
The name tells you the formula. Di- means 2, and tri- means 3, so the formula is S2O3.
What does the formula of ammonia tell you?
The formula of ammonia (NH3) tells you the elemental composition of the compound, indicating that it contains one nitrogen atom and three hydrogen atoms. It also gives you information about the ratio of atoms in the molecule, allowing you to predict its chemical properties and reactions.
What information about a molecule does a chemical formula give you?
A chemical formula provides information about the types and numbers of atoms present in a molecule. It tells you the elements that make up the molecule and their ratios.
What does a chemical formula tell you about a pure substance?
It tells you the elements and the proportions of those elements that are present to make the pure substance.
How many atoms does acetic acid have?
Ethanoic (Acetic) Acid formula is CH3COOH This formula tells us that it contains ;=- 2 x C = Two Carbons 4 X H =(3+1) = Four Hydrogens 2 x O = Two Oxygens. 2 + 4 + 2 = 8 So one molecule of ethanoic acid contains 8(eight) atoms.
What tells what elements a compound contains and the exaxt number of each element in a unit of that compound?
a chemical formula
What does a formula tells about a compound?
The chemical composition of the compound
What does a chemical compound formula tell you?
It tells what elements are present in a molecule and how many atoms of each element are present.
What does a compound formula tell you?
A compound formula, or molecular formula, tells you about the chemical composition of the substance in terms of the number of atoms of that element that are present. From there, the empirical formula may also be derived by simplifying the molecular formula, as well as its structural formula.
What do chemical formulas tell you the number of?
A chemical formula tells you the number of each type of atom in the molecule or structure.
Which symbol in Excel tells it that you are about to enter a mathematical formula?
If the first character of a cell is an equals sign (=), then the cell contains a formula.
What is the chemical formula for the blue disulfur trioxide?
The name tells you the formula. Di- means 2, and tri- means 3, so the formula is S2O3.
What is the chemical symbol showing the elements in a compound?
A chemical formula is the symbolic representation of a compound's elements. It consists of the chemical symbols of the constituent elements and numerical subscripts indicating the number of atoms of each element present in the compound. For example, water's chemical formula is H2O, where "H" represents hydrogen and "O" represents oxygen.
What does the formula of ammonia tell you?
The formula of ammonia (NH3) tells you the elemental composition of the compound, indicating that it contains one nitrogen atom and three hydrogen atoms. It also gives you information about the ratio of atoms in the molecule, allowing you to predict its chemical properties and reactions.
What information about a molecule does a chemical formula give you?
A chemical formula provides information about the types and numbers of atoms present in a molecule. It tells you the elements that make up the molecule and their ratios.
What is a set of symbols that tells how many of each type of atoms are found in a molecule?
This is a chemical formula.
What is the formula for chromium III sulfide?
Chromium III is Cr3+. The roman numeral tells you the charge. Sulfide is S2-. You can figure this out from the periodic table. Sulfur needs two electrons to be like Argon, the next noble gas. When they form a compound, they combine in a ratio such that the total positive charge balances the total negative charge. 2 Cr3+ ions have a total charge of +6. 3 S2- ions have a total charge of -6. So the formula is Cr2S3.
