Sentence examples for of multiple proportions from inspiring English sources

As the Swedish chemist Jöns Jacob Berzelius wrote to Dalton: "The law of multiple proportions is a mystery without the atomic theory".

Thus, Gay-Lussac's law relates volumes of the chemical constituents within a compound, unlike Dalton's law of multiple proportions, which relates only one constituent of a compound with the same constituent in other compounds.

Dalton predicted that, when two elements combine in a series of compounds, the ratios of the masses of one element that combine with a fixed mass of the second are reducible to small whole numbers; this is now known as the law of multiple proportions.

On the basis of the law of definite proportions, Dalton deduced the law of multiple proportions, which stated that when two elements form more than one compound by combining in more than one proportion by weight, the weight of one element in one of the compounds is in simple, integer ratios to its weights in the other compounds.

Dalton's measurements, crude as they were, allowed him to formulate the Law of Multiple Proportions: When two elements form more than one compound, the masses of one element that combine with a fixed mass of the other are in a ratio of small whole numbers.

This is the law of multiple proportions, predicted by Dalton and soon confirmed by a range of experiments.

Ostwald even attempted to derive the basic chemical laws of constant and multiple proportions without the help of the atomic hypothesis.

The contemporary laws of constant and multiple proportions deal with a concept of elemental proportions understood on the basis of the concept of mass.

The χ or Fisher's exact test was used to compare categorical variables between groups and as a test of heterogeneity among multiple proportions.

BHI containing Pac-525 peptide at concentrations of 0.125 mg/mL, 0.25 mg/mL, and 0.5 mg/mL (equal to the multiple proportions of MBC) was added into the wells and was further aerobically incubated at 37°C for 24 h.

With his discovery of multiple combining proportions in acid salts in 1808, he also supplied crucial support for the English scientist John Dalton's atomic theory, and he invented a widely used slide rule of chemical equivalents in 1813.
