How many atoms are represented in the formula?
A chemical formula is the representation of a molecule of a chemical compound; all the atoms from the molecule of this compound need to be represented in the formula.
Is HOH a compound?
yes it a compound since it is made by chemical composition hydrogen and oxdie to give chemical formula H0H it is also soluble hydrogen but OH is an element
What is the chemical name for the main compound in limestone Give the name not the formula?
The main compound in limestone is calcium carbonate.
Give a chemical compound for carbon and bromine only?
A compound that consists solely of carbon and bromine is CBr4. This compound goes by several names. These names include carbon tetrabromide and tetrabromomethane, which are the most commonly used.
What information do you need to know to determine the chemical formula of an unknown compound?
We need to know the elements contained in this molecule and the percentages.
How many atoms are represented in the formula?
A chemical formula is the representation of a molecule of a chemical compound; all the atoms from the molecule of this compound need to be represented in the formula.
How do you identify and kinds of atoms in a given compound based n its chemical formula?
The chemical formula is representative for a molecule and give indication about the chemical composition.
What does a chemical formula communicate?
A chemical formula shows the composition of a substance. It shows the elements present and their relative numbers. There are several types of formula which give specific types of information, but that's the basics.
What does the formula tell us about a chemical compound?
The formula of a chemical compound tells us the types and number of atoms that are present within the compound. It provides information about the elements the compound is composed of and the ratio in which these elements are combined. Additionally, the formula can give us hints on the structure and properties of the compound.
Is HOH a compound?
yes it a compound since it is made by chemical composition hydrogen and oxdie to give chemical formula H0H it is also soluble hydrogen but OH is an element
Does a chemical formula indicate the relative number of molecules of each kind in a chemical compound?
yes, for example H2O (water) there are 2 hydrogen molecules and 1 oxygen. There are other kinds of chemical formula, such as the empirical formula that give you the smallest ratio of atoms, for example glucose C6H12O6 (6 carbons 12 hydrogens and 6 oxygens) would be CH2O however it should state if the formula is any other type then just the normal chemical formula.
What is the chemical name for the main compound in limestone Give the name not the formula?
The main compound in limestone is calcium carbonate.
Empirical formulas describe the types of atoms in a compound and their?
An empirical formula give information about the chemical composition of a compound. Example: tetracycline with the empirical formula C22H24N2O8 has the following composition: - carbon 59,44 % - oxygen 28,81 % - nitrogen 6,30 % - hydrogen 5,45 % If you're with plato the answer is ratios
Give a chemical compound for carbon and bromine only?
A compound that consists solely of carbon and bromine is CBr4. This compound goes by several names. These names include carbon tetrabromide and tetrabromomethane, which are the most commonly used.
What is a formula unit and give example?
A formula unit is the smallest ratio of ions represented in an ionic compound. It is the simplest ratio of elements in a compound. For example, in table salt (NaCl), the formula unit is NaCl, representing one sodium ion (Na+) and one chloride ion (Cl-) in the compound.
What is molecular composition and give an example?
Methane has the chemical formula CH4; hydrogen is 25 % and carbon 75 %.
Why are oxidation numbers important when writing a chemical formula?
Oxidation numbers help determine the ratio of elements in a compound, which is essential for writing a correct chemical formula. They allow you to balance the charges of the ions or atoms present to ensure overall charge neutrality in the compound. Additionally, oxidation numbers give insight into the transfer of electrons during chemical reactions.
