Answer : The correct option is, gamma rays only

Explanation :

Penetration power : It is defined as the movement of particles or rays through an object. As more the energy of a particle, 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 given rays varies greatly.

The alpha particles can be restricted by a few pieces of paper.

The beta particles can be pass through the paper but can not pass by the aluminum foil.

The blocking of gamma rays are the most difficult. It can be blocked by concrete, lead, or other heavy shielding.

Hence, the radiation can pass through the sheet of metal and hit the target is, gamma rays only

When large masses of magma solidify very slowly far below earths surface, they form igneous rocks that have a ___?
evablogger [386]

The answer is; D,

Because these rocks cool slowly, the rocks are able to form large crystals hence giving the rock a coarse texture. These crystals are big enough to be viewed with the unaided eye. The opposite is extrusive rocks that form on the surface of the earth. These cool rapidly and form fine-grained textured rocks because of the small crystals formed during the rapid cooling process.

Rate law equation The rate of a chemical reaction depends on the concentrations of the reactants. For the general reaction betwe
Studentka2010 [4]

Explanation:

In the following reaction;

aA+bB⇌cC+dD

A and B are the reactants while C and D are the products.

a, b, c and d are regarded as coefficients.

The dependence of the reaction on the concentration of the reactants is given by the rate law.

This is given by;

rate= k [A]^m [B]^n

where

K = Rate constant. Constant for the reaction at that temperature.

m = order of reeaction with respect to A

n = order of reaction with repsect to B

Overall order of reaction is given by m + n

Based on the activity series provided, which reactants will form products? f &gt; cl &gt; br &gt; i cui2 br2 right arrow. cl2 al
dimaraw [331]

The reactants that will form products will be 2CuI_2 + Br2.

<h3>Activity series</h3>

Elements at higher positions in the activity series will be able to displace those in lower positions in solutions.

Thus:

2CuI_2 + Br2 --- > 2CuBr +2 I_2 because Br is higher than I in the activity series.

Cl cannot displace F in Cl2 + AlF_3 because F is higher than Cl in the activity series.

Also, Cl is higher than Br in the activity series, thus, the reaction Br_2 + NaCl cannot form products.

I cannot displace F, thus, CuF_2 + I_2 cannot form products.
