Characteristics of α, β, and γ rays
1 answer:
Answer:
1. it is symbolized as 4/2 He : Alpha rays
2. it has the weakest penetrating power : Alpha rays
3. It is a high-speed electron : beta rays
4. It possesses neither mass nor charge : gamma rays
5. it has the strongest penetrating power : beta rays
6. its is symbolized as 0/-1e : beta rays
7. it is the most massive of all the components: alpha rays
Explanation:
Let us consider the characteristics of each of the given rays.
α rays: These are helium nucleus so are symbolized by
Due to two protons and two neutrons unlike beta and gamma rays these are the most massive and thus have least penetrating power among the three given rays.
β rays: These are actually high speed electrons and are symbolized as . Due to lesser mass than alpha rays they are more penetrating than them however less penetrating than gamma rays.
γ rays : They carry no charge or mass. Due to least massive among the three rays they have highest penetrating power.

Answer:
(a) Increasing the temperature adds heat which is a reactant shifting the equilibrium rightwards.
(b) Pressure has no effect since the change in the number of moles is zero.
Explanation:
Hello,
In this case, one could represent the given reaction as:
Since it is endothermic. Thus, solving the (a) statement, one identifies the heat as a reagent, that is why the reaction cools down as it progress, therefore, by increasing the temperature, heat is added, that is, a reagent is added, which shifts the equilibrium rightwards, in other words, more NO is produced so its concentration increases.
Furthermore, for the (b) statement, since the change in the number of moles is zero, based on the stoichiometric coefficients as shown below:
Such value implies that the pressure has no effect on the concentration, taking into account the following form of the law of mass action:
Thus, since ,
, so no effect in concentration is due to the pressure.
Best regards.
