Answer:

gamma rays only is the correct answer.

Explanation:

Every radiation has different penetrating power to penetrate in materials and the flow of particles through a material is called penetration power.

Penetrating power of the gamma rays is very high because it has no mass and charges that the reason it can travel far in the air than beta particles and alpha particles.

Alpha particles can be blocked by paper and beta particles can easily passes through paper but it cannot pass through aluminum sheet whereas gamma particles are hardest to blocked, gamma particles can be blocked by heavy shielding.

Thus the radiation can pass through sheet of metak and hit the target is only gamma rays.

For the process 2SO2(g) + O2(g) --> 2SO3(g),

CaHeK987 [17]

Answer:

–187.9 J/K

Explanation:

The equation that relates the three quantities is:

$\Delta G = \Delta H - T \Delta S$

where

$\Delta G$ is the Gibbs free energy

$\Delta H$ is the change in enthalpy of the reaction

T is the absolute temperature

$\Delta S$ is the change in entropy

In this reaction we have:

ΔS = –187.9 J/K

ΔH = –198.4 kJ = -198,400 J

T = 297.0 K

So the Gibbs free energy is

$\Delta G=-198,400-(297.0)(-187.9)=254.2 kJ$

However, here we are asked to say what is the entropy of the reaction, which is therefore

ΔS = –187.9 J/K

Type of bond between na+1 ion and Cl-1 ion is ion

makvit [3.9K]

A neutral sodium atom, for example, contains 11 protons and 11 electrons. By removing an electron from this atom we get a positively charged Na+ ion that has a net charge of +1. Atoms that gain extra electrons become negatively charged. A neutral chlorine atom, for example, contains 17 protons and 17 electrons.
