What shapes have the smallest surface area per volumn?
The fewer the number of sides that a polygon has, the higher the surface area to volume ratio. This increases until the polygon has an infinite number of sides, or has become a perfect sphere, when the ratio is the smallest.
What is the lowest whole number ratio of ions in an ionic compound called?
an empirical formula For an ionic compound, the empirical formula is called a formula unit.
How do you calculate a ratio from a percent?
Formula to calculate the ratio
What is the ratio 18 to12 in its smallest form?
3:2
What is the empirical formula of a compound that contains 32.39 percent sodium 22.53 percent sulfur and 45.07 percent oxygen?
First assume you have 100 g of the substance & then convert to moles using the molecular weight of each element:Na: 32.39 g / (22.99 g/mol) = 1.409 mol NaS : 22.53 g / (32.07 g/mol) = 0.703 mol SO : 45.07 g / (16.00 g/mol) = 2.817 mol ONext divide each mole amount by the smallest one of the group, in this case sulfur. This gives you the ratio of each element in the compound.Na: 1.409 mol / 0.703 mol = 2.00S : 0.703 mol/0.703 mol = 1.00O: 2.817 mol/0.703 mol = 4.01Round to the nearest whole number & you get the formula: Na2SO4 (sodium sulfate)
What is The smallest whole-number ratio of the element in an ionic or covalent bond?
The smallest whole-number ratio of elements in an ionic or covalent bond is determined by the lowest whole-number ratio of atoms present in the compound's chemical formula. For example, in water (H2O), the ratio of hydrogen to oxygen atoms is 2:1, hence the smallest whole-number ratio.
An empirical formula may not be the smallest whole number ratio of atoms in a compound true or false?
True. An empirical formula is the simplest whole number ratio of atoms in a compound, but it may not always be the smallest possible ratio. The molecular formula, which gives the exact number of atoms in a compound, may be a multiple of the empirical formula.
The formula of a compound with the smallest ratios is called?
The formula of a compound with the smallest ratios is called the empirical formula. It represents the simplest whole-number ratio of atoms in a compound.
Which formula of a compound has the smallest whole-number mole ratio of elements?
The compound with the smallest whole-number mole ratio of elements can be determined from its empirical formula, which represents the simplest whole-number ratio of atoms in the compound. To find this, divide each element's molar amount by the smallest molar amount present in the compound.
What is he smallest whole number ratio of the elements in an ionic or covalent compound?
The smallest whole number ratio of elements in an ionic or covalent compound is known as the empirical formula. It represents the simplest ratio of atoms of each element in a compound.
What is the smallest whole-number ratio?
formula unit
The empirical formula may not represent the actual composition of a?
compound accurately because it only gives the simplest whole number ratio of elements in a compound. It does not provide information about the actual number of atoms or the arrangement of atoms in the molecule.
The empirical formula is always the accepted formula for what?
The lowest whole-number ratio of atoms in a molecule
What formula gives the lowest whole-number ratio of moles of atoms in a mole of molecules?
The formula that gives the lowest whole-number ratio of moles of atoms in a mole of molecules is the empirical formula. This formula represents the simplest whole-number ratio of atoms in a compound. It is determined based on the elemental composition of the compound.
What tells the ratio of atoms?
The ratio of atoms is determined by the chemical formula of a compound. This formula indicates the type and number of atoms present in a molecule. The subscripts in a chemical formula provide the ratio of each type of atom in the compound.
Which best describes an empirical formula?
An empirical formula represents the simplest whole-number ratio of elements in a compound. It does not provide the actual number of atoms of each element in a molecule, but it gives the relative proportion of each element present.
When determining empirical formulas from laboratory data the mole ratio is used to determine what?
The mole ratio is used to determine the ratio of atoms of different elements in a compound. This information helps in identifying the empirical formula of the compound based on the smallest whole number ratio of atoms present in the compound.
