Did J J Thomson's experiments with cathode rays lead to the discovery of the neutron?
No. JJ Thomson's experiments with cathode rays lead to the discovery of the electron.
What are the the contributions of Antoine Laurent Lavoisier to field of chemistry?
Antonine Laurent Lavoisier's contributions: Research on gases, water, and combustion Antoine Lavoisier's famous phlogiston experiment. The work of Lavoisier was translated in Japan in the 1840s. Pioneer of stoichiometry Lavoisier's researches included some of the first truly quantitative chemical experiments. Analytical chemistry and chemical nomenclature Lavoisier investigated the composition of water and air, which at the time were considered elements. Legacy Constant pressure calorimeter. Lavoisier's fundamental contributions to chemistry were a result of a conscious effort to fit all experiments into the framework of a single theory.
Who discovered water is not element?
Antoine Lavoisier, a French chemist, is credited with discovering that water is not an element but a compound of hydrogen and oxygen. He conducted experiments in the late 18th century that led to the understanding of water's composition.
Who discovered the elements of water?
Antoine Lavoisier and Joseph Priestley independently discovered that water is composed of hydrogen and oxygen in the late 18th century. Lavoisier demonstrated this through experiments and chemical analysis, while Priestley isolated oxygen from water through his own experiments.
How did Lavoisier use the scientific method?
Lavoisier applied the scientific method by conducting systematic experiments, making detailed observations, and analyzing data to develop theories and explanations for chemical reactions. He emphasized the importance of precise measurements and reproducibility in his work, which laid the foundation for modern chemistry.
How did lavoisier wife help him to communicate the results of his experiments?
Marie Paulze Lavoisier was instrumental in bringing his experiments to publication as she translated documents and illustrated his scientific texts with incredible competence and efficiency.
What experiments did Antoine Lavoisier perform?
Lavoisier conducted a number of experiments that were based on the assumption that matter can neither be created nor destroyed and validated it through the experiments. This led to the formulation of the Law of Conservation of Mass (or Matter).
What did Lavoisier makes to chemistry?
He was the first to use scientific experiments to learn about atoms.
Why was it important for lavoisier to use sealed in his experiments?
To not let the gas come out ( His Expirement )
Did Thompson's experiments led to the discovery of the neutron?
no
Where and when did Antoine Lavoisier discover oxygen?
Antoine Lavoisier did not discover oxygen. However, he conducted experiments on oxygen and established the role it plays in combustion and respiration. These experiments helped contribute to the understanding of oxygen's properties and its importance in chemical reactions.
Did J J Thomson's experiments with cathode rays lead to the discovery of the neutron?
No. JJ Thomson's experiments with cathode rays lead to the discovery of the electron.
Why was it important for lavoisier to use sealed containers in his experiments?
To not let the gas come out ( His Expirement )
What significant did Lavoisier make to chemistry?
He was the first to use scientific experiments to learn about atoms.
What significance contribution did Lavoisier make to chemistry?
He was the first to use scientific experiments to learn about atoms.
Why could the neutron not be discovered in same experiments as the electron and proton?
Early experiments were based off attraction. The neutron had no charge to attract or repel or to be attracted or repelled. so these experiments could not figure out that there was a neutral particle in the nucleus.
What distinguishes Lavoisier's experiments from his predecessor's?
His experiments were based on quantitative data, not qualitative. Also, he was extremely accurate which was not the case for his predecessors. This allowed him to then develop the Law of Conservation of Mass.
