In general, the electron pairs in a molecule that will adopt a shape to maximize their distance far apart, even charges repel each other as well as unlike charges attract,
for example H2O has two lone electrons pairs but it adopts an angular shape. Hope this help!!
Answer:
Explanation:
= First mass of water = 12 oz
= Second mass of water = 20 oz
= Temperature difference of the solution with respect to the first mass of water = 
= Temperature difference of the solution with respect to the second mass of water =
c = Specific heat of water
As heat gain and loss in the system is equal we have
The final temperature of the solution is .
Answer:
Average atomic mass = 63.553 amu.
Explanation:
Given data:
Abundance of Y-63 = 69.17%
Abundance of Y-65 = 100 - 69.17 = 30.83%
Atomic mass of Y-63 = 62.940 amu
Atomic mass of Y-65 = 64.928 amu
Atomic mass of Y = ?
Solution:
Average atomic mass= (abundance of 1st isotope × its atomic mass) +(abundance of 2nd isotope × its atomic mass) / 100
Average atomic mass= (62.940×69.17)+(64.928×30.83) /100
Average atomic mass = 4353.560 + 2001.730 / 100
Average atomic mass = 6355.29 / 100
Average atomic mass = 63.553 amu.
Answer:
History is the study of the past in all its forms. Philosophy of history examines the theoretical foundations of the practice, application, and social consequences of history and historiography. It is similar to other area studies – such as philosophy of science or philosophy of religion – in two respects.
