I think the correct answer from the choices listed above is option C. Radiation, Chemical agents and Viruses may cause genetic mutations. These substances are known to have mutagenic effects to humans. As you look at MSDS of some chemical agents you can see these effects. Long exposure to radiation are said to bring this effect. Lastly, viruses can influence genetics.

How to find electronegativity differences

lidiya [134]

To calculate electronegativity, start by going online to find an electronegativity table. You can then assess the quality of a bond between 2 atoms by looking up their electronegativities on the table and subtracting the smaller one from the larger one. If the difference is less than 0.5, the bond is nonpolar covalent.

4. Balance the following chemical equation. Say what the coefficients "a"

lisabon 2012 [21]

Answer:

a = 4

b = 3

Explanation:

SOLUTION :-

Balance it by using 'hit & trial' method , and you'll get the answer :-

2Fe₂O + 3C → 4Fe + 3CO₂

⇒ a = 4 ; b = 3

VERIFICATION :-

In reactant side of equation :-

Number of atoms in Fe = 2×2 = 4
Number of atoms in O = 2×3 = 6
Number of atoms in C = 3×1 = 3

In product side of equation :-

Number of atoms in Fe = 4×1 = 4
Number of atoms in C = 3×1 = 3
Number of atoms in O = 3×2 = 6

Number of atoms of each element is equal in both reactant & product side of equation. Hence , the equation is balanced.
