What information is needed to calculate the percent composition of a compound?
The formula of the compound and the Atomic Mass of its elements.
What is white crystalline compound called?
A white crystalline compound could be a wide range of substances, such as salt (sodium chloride), sugar (sucrose), or aspirin (acetylsalicylic acid). More specific information is needed to identify the compound accurately.
Is white crystalline solid a compound or an element?
A white crystalline solid can be either a compound or an element. It depends on the specific substance in question. For example, table salt (sodium chloride) is a white crystalline compound, while pure elemental sulfur can also be a white crystalline solid. Testing and analysis are usually needed to determine whether the solid is a compound or an element.
How many hydroxide ions are needed to form a neutral ionic compound with an aluminum ion?
Three hydroxide ions are needed to form a neutral ionic compound with an aluminum ion. Aluminum has a charge of +3, while hydroxide has a charge of -1 per ion. Therefore, the formula Al(OH)3 is needed for a neutral compound.
What type of change is needed to break down a compound?
Chemical change is needed to break down a compound. It involves breaking the chemical bonds that hold the molecules of the compound together, resulting in the formation of new substances. This process can be brought about by various means such as heat, light, or the presence of other chemicals.
What information is needed to calculate the percent composition of a compound?
The formula of the compound and the Atomic Mass of its elements.
What two elements are chemically combined in a compound?
atoms of hydrogen and oxygen chemically combined to form water
What is the molecular formula of a compound that has the molar mass of 207?
Without further information, it's not possible to determine the molecular formula of a compound just from its molar mass. Additional details about the elements present and their respective ratios are needed to ascertain the specific molecular formula.
What is the chemical name O7?
The chemical name O7 does not correspond to a specific compound. In chemical nomenclature, the symbol O represents oxygen, but the number 7 on its own does not provide enough information to identify a particular molecule. More details, such as the elements involved and their proportions, are needed to determine the specific compound.
What information is needed to determine the orientation of the orbital?
Magnetic quantum number (m_l) is needed to determine the orientation of an orbital.
Is the amount of elements needed to make a compound always the same?
The proportions are always the same.
Which two pieces of information about a country are needed to determine its determine its population density?
population and life expectancy
What additional information is needed to calculate the molecular formula from the percent by mass of each element in a compound?
In addition to the percent by mass of each element, you also need the molar mass of each element. This information allows you to convert the percent by mass into grams and then into moles, which is necessary to determine the empirical formula and subsequently the molecular formula of the compound.
True or false Mendeleev needed to organize information about 63 elements?
True
What information is needed to determine molecular formula?
the empirical formula and the molar mass
What information is needed for a mortgage calculator?
"The information that is needed for a mortgage calculator will be income and source of other income, debt and other assets that can be used to determine payments."
What is the formula for Hydrogen fluoride?
HF This is an example of a covalent compound, so prefixes are needed to determine how many of each atom are in the compound. Since there are none, it is given that there are one of each.
