How do you know if a molecular compound has a dipole-dipole attraction?

A dipole moment is defined as a measure of the molecular polarity of a compound; the magnitude of the partial charges on the ends of a molecule times the distance between them (in meters). In order for there to be a dipole moment the element must must have molecular polarity which results from molecules with a net imbalance of charge (often a result of differences in electronegativity). If the molecule has more than two atoms, both shape and bond polarity determines the molecular polarity. In general look for a difference in electronegativity of the elements of a molecule which results in polarity and thus a possible dipole moment. Note that molecular shape influence polarity so molecules with the same elements but a different shape (and vice versa) won't have the same dipole moment.

Do you need to know atomic weight to calculate molarity?
Yes, you definitely need to know the molecular weight of a compound to calculate molarity.
A compound has a mass of 16.7g 12.7g Iodine 4g Oxygen Therefore the empirical formula is I2O5 What additional information do you need to work out the molecular formula?
You need to know the Relative Molecular Mass of the compound, then you find the ratio of that compared to the R.M.M. of I2O5 and then multiply the ratio by I2O5. That should be it.
What do you know about chemical compound by looking at it's chemical formula?
the number and kinds of atoms in the compoundIn an ionic compound, the formula gives the ions and their ratios in the crystal lattice. In a molecular compound, the formula gives the numbers of atoms of each element in a molecule.
Is chocolate a solute or solvent?
I don't know absolutely for certain but chocolate is an organic compound which probably means it has covalent bonding. Also is melts at a low temperature and forms a suspension in water which are characteristics of a simple molecular structure which would mean it is not ionic. No I don't think chocolate is an ionic compound.
What steps are used to convert an empirical formula into a molecular formula?
By determining the molecular mass, then dividing the molecular mass by the formula mass of the empirical formula to determine by what integer the subscripts in the empirical formula must be multiplied to produce the molecular formula with the experimentally determined molecular mass.
The molecular mass of the compound is 132 amu. What is the molecular formula?
This is impossible. In order to find this you must know the elements in the compound
What are similarities between molecular formula and empirical formula of a compound?
Both formula helps us to know what types of molecules are involved in the compound
Do you need to know atomic weight to calculate molarity?
Yes, you definitely need to know the molecular weight of a compound to calculate molarity.
What is the number of apples in 0.25 moles of apples?
The question does not contain enough information. The equation is number of moles = mass (of compound) / molecular mass of compound. You do not know the weight of an apple (cannot get one specific figure for this), nor does an apple have a molecular weight
What do you know about a chemical compound by looking at its chemical compound?
the number and kinds of atoms in the compoundIn an ionic compound, the formula gives the ions and their ratios in the crystal lattice. In a molecular compound, the formula gives the numbers of atoms of each element in a molecule.
Substance X is a molecular compound and is not an acid Based just on this information what can you determine about substance X?
X is not an electrolyte, since you know that it isn't an acid. molecular compounds can be both soluble and insoluble.
How do you know a compound is ionic or molecular?
An ionic compound is a pure substance that is formed from a metal and a nonmetal. It has a fairly high melting point and is a conductor of electricity when in a molten or aqueous state . A molecular compound, on the other hand, is a pure substance that is formed from nonmetals. It has a fairly low melting point, and cannot conduct electricity regardless of state. Another important difference between the two is that an ionic compound is a crystalline solid at standard ambient temperature and pressure (SATP), whereas a molecular compound can be in a solid, gas or liquid state at SATP.
How do you calculate grams of a compound in a solution?
- measuring the mass of this compound and the volume (or mass) of the solution - by chemical analysis (and determination of the concentration of this compound) If you know the molarity, multiply moles by molecular weight and adjust per the volume you have. If you don't know the molarity, a simple means is to just evaporate the solvent and weigh the remaining compound
