The formula for table salt is NaCl. According to the law of definite proportions this means that the formula for table salt?
Yes, the formula unit of sodium chloride is NaCl.
What shows the kinds and proportions of atoms in a compound?
A chemical formula shows the kinds and proportions of atoms in a compound. The subscripts in a chemical formula represent the number of atoms of each element present in the compound. For example, in the compound H2O, there are two atoms of hydrogen (H) and one atom of oxygen (O).
Are elements that make up a compound always present in the same proportions?
No, elements in a compound are not always present in the same proportions. The ratio of elements in a compound is determined by its chemical formula.
A chemical formula shows the kind and number of atoms that form a?
molecule. It is a shorthand way to represent the elements and their proportions in a compound. The formula provides information about the composition of the substance.
When geologist say that a mineral always contains certain elements in the definite proportions they mean that the mineral has a definite?
A chemical formula.
What the chemical formula for chocolate milk?
Chocolate milk is a mixture of a lot of different compounds in varying proportions; it has no "chemical formula".
The formula for table salt is NaCl. According to the law of definite proportions this means that the formula for table salt?
Yes, the formula unit of sodium chloride is NaCl.
What is the emperical formula for C6H12?
Empirical formula gives the proportions of the elements present in a compound but not the actual numbers or the arrangement of atoms. The empirical formula for C6H12 is CH2.

No, elements in a compound are not always present in the same proportions. The ratio of elements in a compound is determined by its chemical formula.
Are the proportions of a compound fixed or not fixed?
The proportions of elements in a compound are fixed, meaning that a specific compound will always have the same ratio of elements by mass. This fixed ratio is determined by the chemical formula of the compound.
Does a substance have a chemical formula?
Not necessarily. Alloys are "substances", but they don't generally have a chemical formula, they're mixtures which are not necessarily in stoichiometric proportions. The same is true for any mixture in general.

How are proportions useful in calculating dosages of medication?
It gives us a formula to go by in figuring the correct amount of medications to give.
What is red and green resulting color?
brown Red + Green = black, grey or brown depending on the formula of the colours and the proportions in which they are mixed.
What does a chemical equation have?
It contain the chemical formula of the specified compounds (reactants and final products), it contains the chemical proportions of a compound (coefficients).
