Answer:
oceanic crust is a thinner layer that lies under the ocean. continental crust is thicker than the oceanic crust and forms landmasses
Hope this is correct!
Answer:
Can yo take the picture complete?
thanks
Explanation:
Answer:
CH₄ + 2O₂ → CO₂ + 2H₂O
Explanation:
This kind of reaction in which a hydrocarbon combines with oxygen gas is a combustion reaction. They are mostly used to produce heat energy that can be transformed into other forms of energy.
Every chemical reaction is made up of reactants and products. The combining species on the left hand side are the reactant and the products are the result of the combination.
Note: in writing chemical equations, the state of matter must always be included.
Reactants : Methane gas CH₄
Oxygen gas O₂
Product: Carbon dioxide CO₂
Water vapor H₂O
CH₄ + 2O₂ → CO₂ + 2H₂O
The answer should be (D) endothermic reaction.
Reason : - Reactions in which energy is absorbed are called endothermic reactions. In your provided question, 150 kcal energy is being <u>absorbed</u>, and thus, we can say that it is an endothermic reaction.
Explanation:
We should have an invariant point condition (The degree of freedom F=0 as per phase rule) for a quadruple point to occur and to test whether this argument is valid or not we must implement phase rule in a given case.
So, as per the Phase Principle F= C-P+2 Here in this situation all types are allotropic implying they consist of the same chemical compound, i.e. each have the same chemical composition.
Then constituents C=1, P= 4 (because they have 4 phases) Also no parameters for the given system are 2, Pressure and Temperature, these are found by including 2 in the formula of phase rule
Therefore, F= 1-4+ 2=-1 is certainly not equal to 0 and therefore the claim that they found a quadruple point is counterfeit.
