Not sure but i think living things adapt to their environment.
Adaptations are traits giving an organism an advantage in a certain environment. And variations of individuals is important for a healthy species. So i think adaptation might be the right answer because animal will try to adapt the certain environment. I hope this answer will help you.
In the question, the number of atoms per unit cell is required for:
A) Polonium (Po)
In polonium, the structure is simple cubic, meaning there are 8 corner atoms, which add up to one atom per unit cell.
B) Manganese (Mn)
The structure of the Mn can be considered to be a body centered cubic (BCC) and the number of atoms for this is 8 corner atoms and 1 central atoms, making a total of 2 atoms per unit cell.
C) Silver (Ag)
Silver has a face centered cubic (FCC) unit cell structure, where there are 8 corner atoms and 6 atoms on the faces, so there are a total of 4 atoms per unit cell.
The given formula for heat, Q=mc(Tf-Ti), is the best way to solve such problems with changes in temperature. It can be said that m is the mass of the substance. C is the specific heat of the substance. The term (Tf-Ti) is the change in temperature.
Q = mc(Tf-Ti) = 480g(0.96 J/g-C)(234-22) = 97689.6 Joules of heat
Answer:
The atomic mass of Zinc is 65.30 Da
Explanation:
<u>Step 1: </u>Data given
3 major isotopes
⇒ Zinc-64
atomic mass = 63.929 Da
Peak intensity = 100
⇒ Zinc-66
atomic mass = 65.9260 Da
Peak intensity = 57.4
⇒ Zinc- 68
atomic mass = 67.9248 Da
Peak intensity = 38.6
<u />
<u>Step 2:</u> Calculate the natural abundance
∑peak intensity = 100 + 57.4 + 38.6 = 196
Zinc-64 : 100/196 = 0.5102 ⇒ 51.02 %
Zinc-66 : 57.4/196 = 0.2929 ⇒ 29.29 %
Zinc-68 : 38.6/196 = 0.1969 ⇒ 19.69 %
<u>Step 3:</u> Calculate the atomic mass if Zinc
63.9291 * 0.5102 + 65.9260*0.2929 + 67.9248*0.1969 = 65.3007 Da
The atomic mass of Zinc is 65.30 Da
