Pachacha [2.7K]

Answer:

a. forming ions, causing reactions that mutate DNA

Explanation:

Ionizing radiation is a type of energy released by atoms in the form of electromagnetic waves or particles. The spontaneous decay of atoms is called radioactivity, and the surplus energy emitted is a form of ionizing radiation. The unstable elements that decay and emit ionizing radiation are called radionuclides.

Exposure of a human being to certain doses of ionizing radiation can cause irreparable changes in the structure of their DNA, that is, in the genes that control the function of cells, and therefore cause a series of changes that can lead to a cancer.

At 1115 degrees Celcius, where iron is still a solid (melting point 1538 degrees Celcius), the unit cell for the most stable cry
svp [43]

<u>Answer:</u> The atomic radius of iron is 128 pm.

<u>Explanation:</u>

To calculate the radius of the metal having FCC crystal lattice, the relationship between edge length and radius follows:

4r=\sqrt{2}a

Where,

a = edge length = 362 pm

r = atomic radius of iron = ?

Plugging values in above equation, we get:

r=\frac{\sqrt{2}\times 362}{4}\\\\a=128pm

Hence, the atomic radius of iron is 128 pm.

Keith_Richards [23]
rate 1 of the reaction = k [A]²

rate 2 of the reaction = k [A/2]² = k[A]² /4

We can see that rate of the reaction will be 4 times less.

Express a fraction that is equivalent to a terminating decimals between 0.5 and 0.75.
olya-2409 [2.1K]
0.5 = 1/2 = 2/4 = 4/8 = 8/16 = 16/32…
0.75 = 3/4 = 6/8 = 12/16 = 24/32…

Then you can easily find the fractions in between are: 5/8, 9/16, 11/16, 17/32, 19/32, 21/32, 23/32...
