How did lavoisier distinguish between compounds and elements?
Lavoisier distinguished between compounds and elements by conducting experiments to show that compounds can be broken down into simpler substances, while elements cannot be further broken down by chemical means. He also proposed the Law of Conservation of Mass, which states that the total mass of substances present before a chemical reaction is equal to the total mass after the reaction, providing further evidence for the distinction between compounds and elements.
What experimental evidence led to the formulation of the law of multiple proportions?
The experimental evidence by John Dalton, who analyzed the ratios of elements combining to form different compounds, led to the formulation of the Law of Multiple Proportions. This law states that when elements form different compounds, the ratio of the masses of one element that combine with a fixed mass of the other element can be expressed in small whole numbers.
What evidence do scientists have that the inert gases are not completeky inert?
Scientists have observed that certain conditions can cause inert gases like xenon, krypton, and argon to form compounds with other elements. Additionally, experiments have shown that inert gases can react with elements under extreme conditions, such as high pressure and temperature. These observations challenge the traditional view that inert gases are completely unreactive.
What experimental evidence do you have for the existence of ionic bonding?
That the disassociated ions conduct electricity. They must be charged and oppositely charged to conduct electricity in solution and the must dissasociate to a reasonable degree to do so. Thus. NaCl Na + ( cation ) and Cl - (anion ) are electrolytes conducting electricity in solution. This is a common chemistry class demonstration.
What evidence convinced John Dalton that elements must be made of individual particles called atoms?
John Dalton was convinced that elements must be made of individual particles called atoms due to his observations of ratios in chemical reactions. He analyzed the ratios at which elements combine with each other to form compounds, and proposed that atoms combine in simple whole number ratios, leading to the development of his atomic theory.
Which is evidence that elements can combine to form new compounds?
Chemical reactions that involve the rearrangement of atoms in reactants to form new compounds are evidence that elements can combine to form new compounds. Additionally, the existence of a wide variety of compounds with unique properties and compositions further supports this concept. The ability to predict the outcomes of chemical reactions using the principles of stoichiometry and chemical bonding also demonstrates the combination of elements to form compounds.
Are coincidences evidence of God's existence?
Not likely. Coincidences are evidence of coincidence, or if you will, random chaos, which is what the universe is all about. Asking if they are evidence of God's existence is like asking if water is evidence of a fish's existence.
Is there any evidence of the Holy Ghost?
Just as there is no evidence for the existence of God, so there is no evidence for the existence of the Holy Ghost. It is a matter of faith, and faith alone.

How can one demonstrate or provide evidence for the existence of gravity?
One can demonstrate the existence of gravity by conducting experiments that show objects falling towards the Earth when dropped, observing the orbits of planets around the sun, and measuring the acceleration of objects due to gravity. These observations and measurements provide evidence that gravity is a force that attracts objects towards each other.
How can one provide evidence or demonstrate the existence of gravity?
One can provide evidence of gravity by conducting experiments that show objects falling towards the Earth when released, observing the orbits of planets around the sun, and measuring the acceleration of objects due to gravity. These observations and measurements demonstrate the existence of gravity as a force that attracts objects towards each other.
Is there evidence for homer's existence?
none.
Is keyshia cole a devil worshiper?
There is no evidence to support this claim. There is no evidence of the existence of a being called "the devil". Scientifically, the existence of a devil is an impossibility.
Where on the moon is there evidence of the existence of ice?
Evidence of frozen water are near the poles
What is the evidence for the existence of crustal plates?
Worldwide, the mountains are the evidence of crustal plates.
Do merpeople exist?
No. There is no evidence of the existence of merpeople.
