What is nucular decay

1 answer:

6 0

Nuclear decay is the decay of atoms on the atomic scale. “Radioactive decay is the process by which an unstable atomic nucleus loses energy by radiation. A material containing unstable nuclei is considered radioactive. Three of the most common types of decay are alpha decay, beta decay, and gamma decay, all of which involve emitting one or more particles or photons.”

The mass of a proton is 1.00728 amu and that of a neutron is 1.00867 amu. what is the binding energy (in j) of a 61co nucleus? (

bazaltina [42]

With the given equations the binding energy is $1.372 *10^{-12} J$ .

<h3>How will you calculate binding energy using the given equations?</h3>

Step 1: The given data is:

The proton's mass 1.00728 amu

The neutron's mass 1.00867 amu

The mass of a cobalt-61 nucleus is 60.9325 amu

Step 2: Calculate binding energy

The mass defect = the difference between the mass of a nucleus and the total mass of its constituent particles.

Cobalt61 has 27 protons and 34 neutrons.

The mass of 27 protons = 27*1.00728 u = 27.19656 u

The mass of 34 neutrons = 34*1.00867 u = 34.29478 u

Total mass of protons + neutrons = 27.19656 u + 34.29478 u = 61.49134 u

Mass of a cobalt61 nucleus = 60.9325 amu

Mass defect = Δm = 0.55884 u

ΔE =c²*Δm

ΔE = $(3.00 *10^8 m/s^2) *(0.55884 amu))*(1.00 g/ 6.02 *10^{23} amu)*(1kg/1000g)=8.36 * 10^{-11} J$

Step 3: Calculate binding energy per nucleon

ΔE $= 8.36* 10^{-11} J$

binding energy $= \frac{8.36* 10^{-11}}{60.9325} J = 1.372 *10^{-12} J$

The binding energy per nucleon $= 1.372 *10^{-12} J$

Do saturated and unsaturated fatty acids have high or low boiling points? ...?

kati45 [8]

The geometry of the double bond is almost always a cis configuration in natural fatty acids. These molecules do not "stack" very well. The intermolecular interactions are much weaker than saturated molecules. As a result, the melting points are much lower for unsaturated fatty acids.
