I don't know terribly much about radioactive decay, but yes, it WILL decay. If it's half life is 25 days, it will be completely consumed in 50 days. By 100 days, it should be long gone. As far as I know, the reason for this is (besides the simple math which is self-explanatory) the Thorium has so many protons/neutrons, it's unstable and thus undergoes radioactive decay as it cannot maintain stable form.

I hope this helps! :)

Categorize each hydrocarbon as being saturated or unsaturated.
Black_prince [1.1K]

As you have not provided the options, still we can figure out the answer by understanding the key difference between saturated and unsaturated hydrocarbons.

SATURATED HYDROCARBONS are those hydrocarbons which only consist of a carbon carbon single bonds. All the bonds are sigma there are no pi bonds at all. Examples are shown below.

While, UNSATURATED HYDROCARBONS are those hydrocarbons which may contain either a double bond or triple bonds or both of them between the carbon atoms as shown below.

Using the VSEPR theory , what would the representation mean A central atom with 2 connected atoms atom with I lone pair of Jone
VLD [36.1K]

Answer:

The molecule has a bent geometry

Explanation:

Let us look again at the principles of VSEPR theory. The shape of a molecule depends on the number of electron pairs that surround the valence shell of the central atom in the molecule.

Lone pairs distort the molecular geometry away from what is expected on the basis of VSEPR theory.

The molecule described in the question has the form AEX2. Two substituents and one lone pair form three electron domains around the central atom. The expected geometry is trigonal planar but the observed molecular geometry is bent because of the lone pairs present.

What is the wavelength (in nm) of the least energetic spectral line in the visible series of the H atom?
grin007 [14]

Answer:

Brackett Series (n = 4)

Explanation:

The least energetic line of Hydrogen atom lies in <em>Brackett Series </em>when n = 4 because these are least energetic, have longer wavelengths and lies in Infrared region of spectrum.  No traces of <em>Pfund series </em>are formed by H=atoms.
