Give evidence to support or dispute: “In nature, the chance of finding one isotope of an element is the same for all elements.”
alekssr [168]

Answer:

False, isotopes have different occurrence percentages, so the changes are different.

Explanation:

Hello,

In this case, since it is false that the isotopes of all the elements can be found with the same chance (occurrence) we can consider the following facts:

1. Carbon atom has two major occurring isotopes: C-12 (98.93%) and C-13 (1.07%).

2. Bromine atom has two major occurring isotopes: Br-79 (50.69%) and Br-81 (49.31%).

3. Calcium has four major occurring isotopes: Ca-40 (96.941%), Ca-42 (0.647%), Ca-43 (0.135%) and Ca-44 (2.086%).

Which show us that the chances of finding any isotope differ among elements.

Regards.

Charlie the Chemist heats a 62.51 g piece of copper from 22.9°C to 345.0°C. Calculate the amount
Ivanshal [37]
  • Mass=m=62.51g
  • Initial temperature=T_i=22.9°C
  • Final temperature=T_f=345.0°C
  • Specific heat of copper=0.0920cal/g°C
  • ∆T=T_f-T_i=345-22.9=322.1°C

\\ \tt\hookrightarrow Q=mc\Delta T

\\ \tt\hookrightarrow Q=62.1(0.0920)(322.1)

\\ \tt\hookrightarrow Q=1840.22172cal

\\ \tt\hookrightarrow Q=1840.222cal

\\ \tt\hookrightarrow Q=1840.2cal
