Jude has a mutation in the gene that codes for a certain digestive enzyme. However, these enzymes function normally.

B., the mass of the nucleus of the atom.
Both the protons and the neutrons are inside the nucleus. The atomic number of an atom is the number of protons, and if you subtract the atomic number from the atomic mass you can find the number of neutrons an atom has.
So, the mass of the protons plus the mass of the neutrons, which are both inside the nucleus, equals the atomic mass.

Which statement best describes the collisions of gas particles according to the kinetic-molecular theory?

Andrew [12]

Answer:

b. As particles travel in straight lines, their paths sometimes meet, and then they bounce apart with no gain or loss of energy.

Explanation:

Kinetic - molecular theory -

According to this theory , gas is considered to be as a large number of very small particles , which moves randomly , and due to this randomness collisions occurs , as the particles collide with each other and the wall of the container .

During these collisions , there is no loss or gain of energy , there is only transfer of energy .

The decay constant for 14C is .00012 In 1947, the famous cave paintings in Lascaux, France were discovered and testing revealed

Andru [333]

The question is incomplete, here is the complete question:

The decay constant for 14-C is $0.00012yr^{-1}$ In 1947, the famous cave paintings in Lascaux, France were discovered and testing revealed that charcoal in the cave contained 20% of the 14-C found in living trees. Write a formula for the age of the charcoal (hence of the associated paintings). Show your work to find this formula.

<u>Answer:</u> The formula for the age of the charcoal is $t=\frac{2.303}{1.2\times 10^{-4}yr^{-1}}\log \frac{100}{20}$

<u>Explanation:</u>

Carbon-14 isotope is a radioisotope and its decay process follows first order kinetics.

Rate law expression for first order kinetics is given by the equation:

$k=\frac{2.303}{t}\log\frac{[A_o]}{[A]}$

where,

k = rate constant = $0.00012yr^{-1}=1.2\times 10^{-4}yr^{-1}$

t = time taken for decay process = ? yr

$[A_o]$ = initial amount of the sample = 100 grams

[A] = amount left after decay process = (100 - 20) = 80 grams

Putting values in above equation, we get:

$1.2\times 10^{-4}=\frac{2.303}{t}\log\frac{100}{20}\\\\t=\frac{2.303}{1.2\times 10^{-4}yr^{-1}}\log \frac{100}{20}$

Hence, the formula for the age of the charcoal is $t=\frac{2.303}{1.2\times 10^{-4}yr^{-1}}\log \frac{100}{20}$
