Answer:
youre gonna have to include the answers for me to help
Explanation:
Answer: Oxygen
Explanation:
As seen from the balanced equation:
2 moles of hydrogen combine with 1 mole of oxygen or 1 mole of hydrogen combine with 1/2 mole of oxygen.
According to Avogadro's law, equal volumes of gases contain equal number of molecules and hence equal number of moles.
Thus if x moles of both gases are present, x moles of hydrogen will combine with 
moles of oxygen and 
moles of oxygen will be left used and will be in excess.
Answer:
Cold water
Explanation:
A simple way to solve this kind of problems is to keep in mind that:
<em>Solids have stronger intermolecular attractive forces than liquids, and liquids have stronger forces than gases.</em>
Cold water behaves more similarly to solids than hot water. Conversely, hot water behaves more similarly to gases than cold water. Thus, cold water has stronger intermolecular attractive forces than hot water.
Dalton's atomic theory was the first complete attempt to describe all matter in terms of atoms and their properties.
Dalton based his theory on the law of conservation of mass and the law of constant composition.
The first part of his theory states that all matter is made of atoms, which are indivisible.
The second part of the theory says all atoms of a given element are identical in mass and properties.
The third part says compounds are combinations of two or more different types of atoms.
The fourth part of the theory states that a chemical reaction is a rearrangement of atoms.
Parts of the theory had to be modified based on the discovery of subatomic particles and isotopes.
The structures and chemistry of individual hydrocarbons depend a large part on the types of chemical bonds that link together the atoms of their constituent molecules. Hydrocarbons are derived by chemical degradation.
