Answer : The correct option is, only alpha particles.

Explanation :

Penetration power : It is defined as the movement of the rays or the particles through the object.  As more the energy of a particle, the more will be the penetrating power.

The ascending or increasing order of the penetration power of the particles will be :

Alpha rays < Beta rays < Gamma rays

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

  • The alpha particles can be stopped by the paper, cloth, human skin.
  • The beta particles can pass through the paper, cloth, human skin but it can not pass through the aluminum foil.
  • The blocking of gamma rays is very difficult. It can be stopped only by concrete, lead, or other heavy shielding.

Hence, the particles can be stopped by human skin is only alpha particles.

A sample of hydrated cobalt (II) chloride has a mass of 5.22 g. After heating, it has a mass of 2.85 g. What is the percent by m
Tom [10]
Answer:
mass of water in hydrate = 2.37 grams

Explanation:
The mass of the hydrated cobalt (III) chloride is the summation of the salt and the water it contains.
This means that:
Total mass of sample = mass of salt + mass of water

Now, we are given that:
total mass of sample = 5.22 grams
mass of salt = mass of sample after heating = 2.85 grams

Substitute to get the mass of water as follows:
5.22 = mass of water in hydrate + 2.85
mass of water in hydrate = 5.22 - 2.85
mass of water in hydrate = 2.37 grams

Hope this helps :)
