Answer:
The unit cell's edge length is 
Explanation:
Number of atom in BCC unit cell = Z = 2
Density of barium metal= 
Edge length of cubic unit cell= a = ?
Atomic mass of Ba(M) = 137.33 g/mol
Formula used :

where,
= density
Z = number of atom in unit cell
M = atomic mass
= Avogadro's number
a = edge length of unit cell
On substituting all the given values , we will get the value of 'a'.


The unit cell's edge length is 
Answer:
Human activities have a tremendous impact on the carbon cycle. Burning fossil fuels, changing land use, and using limestone to make concrete all transfer significant quantities of carbon into the atmosphere. This extra carbon dioxide is lowering the ocean's pH, through a process called ocean acidification.
Explanation:
Not washing sidewalks, taking quick showers and consuming local products are changes that will help to save water and reduce the increase in the temperature of our planet.
<h3>How to save water and protect the planet?</h3>
Not washing the sidewalks, there is a lot of water loss when people wash the sidewalks, looking for other ways to clean the neighborhood is necessary.
Taking baths efficiently, not spending much time in the shower, water will be saved, and new measures to anthropize rivers will not be necessary.
Consume locally produced products, avoiding gas emissions with transport, thus preventing a large amount of fuel from being burned.
With this information, we can conclude that not washing sidewalks, taking quick showers and consuming local products are changes that will help to save water and reduce the increase in the temperature of our planet.

Implantation is the major sign of pregnancy for various women, it is a stage in which a zygote of fertilized egg limplants into the wall of the uterus.
Implantation usually takes place 6 to 10 days post ovulation, or day 20 to 24 of a menstrual cycle. However, it can take place a few days later or earlier. Once fertilization takes place, the egg remains the fallopian tuve for three days prior of getting inside the uterus and starts to implant itself to the walls of the uterus.
