Do atoms combine to form molecules in simple whole number ratios?
They do combine in whole number ratios, but these ratios need not be simple - particularly in some organic compounds.
What do you get with changing ratios that combine in elements?
In this mode different compounds are obtained.
Do elements that combine in changing ratios form mixtures?
When elements combine in changing ratios, they form compounds rather than mixtures. Mixtures are made up of different substances that are not chemically bonded together, while compounds are formed by chemical bonding between elements in specific ratios.
Do atoms combine in only one-to-one ratios to form compounds?
No, this affirmation is not correct.
What color do you get when you combine black and red?
When you combine black and red, you typically get a dark shade of purple or burgundy, depending on the specific ratios used in the mixture.
How did dalton explain the formation of compounds?
Dalton proposed that elements combine in simple whole number ratios to form compounds, based on his atomic theory. He suggested that atoms of different elements combine in specific ratios to form compounds, where each compound has a unique composition. This explanation laid the foundation for understanding chemical reactions and the formation of compounds.
Which elements proved difficult for mendeleev to add to his table because they were found to combine in various ratios with other elements?
The noble gases, such as helium, neon, and argon, were difficult for Mendeleev to add to his table as they were found to be chemically inert and did not easily combine with other elements in fixed ratios. This challenged the periodicity of his table, which was based on the repeating patterns of chemical properties.
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.
Did Dalton's atomic theory state that atoms of different elements combine in simple whole-number ratios can form compounds?
Yes, Dalton's atomic theory included the idea that atoms of different elements can combine in simple whole-number ratios to form compounds. This concept helped explain the law of definite proportions.
What is formed when two or more elements combine?
When two or more elements combine, they form a compound. Compounds are composed of atoms of different elements bonded together in specific ratios.
Daltons atomic theory stated that atoms?
are indivisible and identical in weight and size within a given element. Atoms combine in simple whole-number ratios to form compounds, and chemical reactions involve the rearrangement of atoms.
Oxygen can combine with carbon to form two compounds carbon monoxide and carbon dioxide The ratio of the masses of oxygen that combine with a given mass of carbon is 1 or 2 This is an example of?
Law of multiple proportions, which states that when two elements can combine to form more than one compound, the mass ratios of one element that combines with a fixed mass of the other element will be in small whole number ratios.
