Answer: B

Explanation: Have to be careful here.Clearly, the samples could have different mass, and COULD have different volume and they could be either solid, liquid or gas.

what is cotinental drift defin this term whith three scientific evidnce in 3-5 sentences HELP ME I'LL MAKE YOUR BRAINEST AND YOU
FinnZ [79.3K]
Continental drift is the movement of Earth’s continents over long periods of time. An evidence for this is that some continents look like puzzle pieces that can fit together, such as South America and Africa. Another evidence is that fossils of the same type have been found in different continents, far apart - suggesting that the two continents once were joined. Another evidence is that identical rocks were found at both sides of the Atlantic Ocean by Alfred Wegener, the main developer of the continents drift theory.

A student tested a sample of carbon (C) by combining it with water. There was no reaction between the carbon and water. The stud
solong [7]

Answer:

No, just because carbon did not react with water, does not mean it wouldn't react with a different compound.

Explanation:

It is common knowledge that carbon is not in group 18, because it is found in all living compounds, and this means it must be reactive with many compounds. We know that water is not very reactive, but it is a good solvent. Meaning that many compounds can dissolve in water, but not chemically react with it. Carbon however is not very soluble because it does not create dipoles or hydrogen bonds. This means it will not show any change when in the presence of water, but if combined with oxygen, can form carbon dioxide.

Elemental analysis of a compound containing carbon, hydrogen, nitrogen, and oxygen gave the following mass percentages for each
svetlana [45]

Elemental analysis of a compound containing carbon, hydrogen, nitrogen, and oxygen gave the following mass percentages for each element: C: 42.36% H: 3.555% N: 16.47% O: 37.62% The <em>molar mass</em> of the compound is  Molecular formula = C6H14N2O2 Consider the total mass of the compound =100g Then mass of carbon = 49.30 g Mass of hydrogen = 9.653 g Mass of nitrogen = 19.16 g Mass of oxygen = 21.89 g Molar mass of carbon = 12.0 g/mol

<h3>What is molar mass ?</h3>

In chemistry, the molar mass of a chemical compound is determined by dividing its mass by the molecular weight of the component that makes up the sample. The molar mass of a substance is a bulk attribute rather than a molecular one. The compound's molar mass is an average over numerous samples, which frequently have different masses because of isotopes. A terrestrial average and a function of the relative abundance of the isotopes of the constituent atoms on Earth, the molar mass is most frequently calculated using the standard atomic weights. For converting between a substance's mass and amount in bulk amounts, the molar mass is the proper unit.
