Answer : The correct option is, gamma

Explanation :

Penetration power : It is the movement of rays or the particles through an object.  We know that the more the energy of a particle, the more will be the penetrating power.

The increasing order of the penetration power of alpha rays, beta rays, and gamma rays will be,

Alpha rays < Beta rays < Gamma rays

The penetrating power of the alpha, beta and gamma rays varies greatly.

(1) The alpha particles are restricted by the paper.

(2) The beta particles can pass through the paper but it can not pass through the aluminum foil.

(3) The blocking of gamma rays is very difficult. It can be blocked only by concrete, lead, or other heavy shielding.

Hence, the radiation can only be stopped by thick layers of dense metal is, gamma.

Gamma rays have the highest penetrating power so it can only be stopped by thick layers of dense metal. :)

How is a salt formed during a neutralization reaction?
katen-ka-za [31]

Answer:

C. A metal ion takes the place of the hydrogen of an acid

Explanation:

When an acid react with base neutralization reaction take place.

During neutralization reaction water and salt are formed.

For example;

Base sodium hydroxide react with hydrochloric acid and form sodium chloride and water.

The sodium hydroxide consist of sodium metal ion in the form of Na⁺ and OH⁻. when it react with acid hydrogen atom of acid replace by sodium metal and react with anion of acid and form salt called sodium chloride.

Chemical equation:

NaOH + HCl  →  NaCl + H₂O

How are pressure and temperature related in terms of kinetic energy?
mylen [45]

Answer:

As the temperature of the gas increases, the particles gain kinetic energy and their speed increases. This means that the particles hit off the sides more often and with greater force. Both of these factors cause the pressure of the gas to increase.
