Answer:
The correct answer is - (Choice A) A Photosynthetic plants can move carbon from the atmosphere into an ecosystem’s food web.
Explanation:
Photosynthesis is the process performed by photosynthetic or green plants in presence of light atmospheric carbon dioxide and water converted into glucose (6 carbon compound) and oxygen.
This glucose or sugar is utilized by the plants that are producers in the ecosystem food web. These producers are fed by consumers and carbon molecules transfer from all the trophic levels in the food chain or food web in the process.
Answer:
The sun is at the (edge) of our solar system
and is much (hotter) than anything else in the solar system (95%) of the entire mass of the solar system is contain in the sun
Answer:
a)CN=12
b)APF=74 %
c)a=0.35 nm
d)ρ=9090.9 
Explanation:
Given that
Nickel have FCC structure
We know that in FCC structure ,in FCC 8 atoms at corner with 1/8 th part in one unit cell and 6 atoms at faces with 1/2 part in one unit cell .
Z=8 x 1/8 + 1/2 x 6 =4
Z=4
Coordination number (CN)
The number of atoms which touch the second atoms is known as coordination number.In other word the number of nearest atoms.
CN=12
Coordination number of FCC structure is 12.These 12 atoms are 4 atoms at the at corner ,4 atoms at 4 faces and 4 atoms of next unit cell.
APF
We know that for FCC
Now by putting the values
APF=0.74
APF=74 %
a=0.35 nm
Density
We know that M for Ni
M=58.69 g/mol
a=0.35 nm
ρ=9090.9
Answer:
Explanation:According to the law of conservation of mass (mass remains the same throughout a reaction), mass is conserved in this case. This can be proven by comparing the weight of two enclosed glass containers of the reaction. They will most likely have the same weight because the products the chemical reaction creates would most likely produce a gas that can be trapped if there is no opening in the glass container. To further investigate, compare the weights of the products of the reaction with an enclosed container to another container with no lid of the same reaction.
With an atomic number of 55, that means there are 55 protons. Because electrons do not count towards atomic weight, the element would have 150-55 neutrons. So, 95 neutrons.
