Answer:

D

Explanation:

Gamma radiation penetrates the cell wall of prokaryotic organisms such as bacteria and can inhibit their metabolic functions as well as destroy their DNA.

Debunking the other answers:

A is incorrect as Gamma radiation is used in the treatment of cancer via radiotherapy.

B is incorrect as Gamma rays are too small and would just penetrate any smoke particles.

C is incorrect because Gamma rays are used to disinfect food products to prevent food borne illness. Irradiation is safe to use on food and does not make it radioactive.

Thus, D is correct.

pishuonlain [190]

Answer:

Succinic acid

Explanation:

The most common possibility is succinic acid

As it has decimals after whole no till hundredth it contains OH and C in most of the cases .

Let's check for succinic acid

  • C4H_6O_6
  • 4(12)+4(16)+6
  • 64+48+6
  • 118u

Yes approximately equal

Molecular formula is.

Cabr2 will most likely dissolve in which solvent? 1. bi3 2. h2o 3. br2 4. ccl4 5. c8h18
77julia77 [94]
General principle of solubility is 'like dissolves like'

CaBr_{2} is an ionic compound, wherein the constituent ions (Ca^{2+} and Br^{-}) are held by electrostatic forces of interaction. 

Such ionic compounds are soluble in polar solvents. 

Among the solvent mentioned in question, water (H_{2}O) has maximum polarity. Hence, CaBr_{2} is most likely to dissolve in H_{2}O

What is the number of moles of H2O produced if you combust two moles of CH4 according to the following balanced equation? CH4 +
loris [4]
The combustion of Methane produces CO₂ and water;

                         CH₄  +  2 O₂     →      CO₂  +   2 H₂O

According to balance equation,

        1 Mole of CH₄ on combustion give  =  2 Moles of H₂O
So,
                  2 Moles of CH₄ will produce  =  X Moles of H₂O

Solving for X,
                               X  =  (2 Moles × 2 Moles) ÷ 1 Mole

                               X  =  4 Moles
Result:
           4 Moles 
of H₂O is produced on combustion of 2 Moles of CH₄.

The nonmetals include which of the following groups? Use the periodic table to answer the question. Check all that apply. haloge
kykrilka [37]

Answer is: halogens ans noble gases.

The nonmetals are divided into two categories: reactive nonmetals and noble gases.

Halogen elements are in group 17: fluorine (F), chlorine (Cl), bromine (Br) and iodine (I). They are very reactive and easily form many compounds.

Noble gases are in group 18: helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe) and radon (Rn). They have very low chemical reactivity.
