We know that,
acceleration (a) = final velocity(V)-initial velocity(U)/ Time taken(T)
The rate at which radioactive decay occurs & how much radioactive decay has occurred
Answer:
Boron has a larger radius and the protons in carbon exert more pull.
Explanation:
Remember than elements have greater radius as they are closer to the bottom left corner, so boron would have the larger radius here. Carbon has a smaller radius, which makes it easier for the protons in carbon to exert more pull.
Answer:
protista, fungi, plant, animal
Explanation:
this is the answer
The statement that is true among the given statements is ΔH1 = 2ΔH2. The correct option is d. ΔH1 = 2ΔH2
From the question,
We are to determine which of the given statements is true.
From the given reactions,
We have
1. N2 (g) + O2 (g) ----> 2NO (g) ΔH1
and
2. 1/2 N2 (g) + 1/2 O2 (g) ---> NO (g) ΔH2
ΔH1 is the enthalpy change for reaction 1
and
ΔH2 is the enthalpy change for reaction 2
Enthalpy is an extensive property. The enthalpy change for a given reaction depends on the stoichiometry of the reaction.
From the given equations,
We can observe that the stoichiometry of reaction 1 is twice that of reaction 2.
Therefore, the enthalpy of reaction 1 will also be twice the enthalpy of reaction 2
That is,
ΔH1 = 2ΔH2
Hence, the statement that is true among the given statements is ΔH1 = 2ΔH2. The correct option is d. ΔH1 = 2ΔH2
