combinedAnswer
It can be two or more of the same elements combine together
It can be two or more different elements combined
Step-by-step explanation:
A molecule is a group of two or more atoms that form the smallest identifiable unit into which a pure substance can be divided and still retain the composition and chemical properties of that substance.
A molecule can also be two or more different elements combined.
A mixture of hydrogen and oxygen would not need to have a certain ratio of hydrogen atoms to oxygen atoms to differ from the compound known as water.
<h3>Why is water a compound not a mixture?</h3>
A water molecule has 2 hydrogen atoms bonded chemically to oxygen atoms and has the formula H₂O.
In a chemical reaction, two atoms react together chemically to form a new product which means the reactants lose their individual properties and obtain new properties of the product formed.
Hence, water is a compound as hydrogen and oxygen atoms are bonded chemically to each other.
On the other hand, if oxygen and hydrogen form a mixture which is a physical change then they retain their individual properties in the mixture. They do not need to be in a specific ratio and there are no chemical changes taking place.
Chemical change determines if a substance is a mixture or a compound.
Thus, a mixture of hydrogen and oxygen is different from water if it doesn't have a certain ratio of hydrogen atoms to oxygen atoms.

Answer:
Pressure will double
Explanation:
Gay - Lussac Law => P ∝ T with volume and mass held constant.
=> P₁/T₁ = P₂/T₂ => P₂ = P₁T₂/T₁
T₂ = 2T₁
P₂ = P₁(2T₁)/T₁ = 2P₁
Double absolute temperature => double pressure
Answer:
monochlorinated products: 4
dichlorinated products: 12
Explanation:
Chlorination of alkanes is a reaction that takes place when the chlorine is in presence of light. This actually decomposes the chlorine, and one atom of Chlorine substracts an hydrogen from the alkane. Now, this hydrogen substracted comes usually from the most substitued carbon, because it's more stable (A tertiary carbon is more stable than a secondary carbon, and this more stable than primary).
When this happens, the other chlorine atom, goes as electrophyle in that carbon and formed the chlorinated product. Now, although a tertiary carbon is more stable, we can still have (in minor quantities) chlorinated products that comes from a secondary and primary carbon. The first picture shows the general mechanism of the chlorination, and the possible products for a monochlorinated.
The second picture shows the possible dichlorinated products, which are in higher quantities than the monochlorinated basicallu because of the variety of positions the chlorine can be. So, second picture shows all the products.
