Explanation:
Circular lines on topographic map is called Contour lines these lines shown on two dimension map and depict elevation on the ground . the distance of each contour line is set to represent a certain level of elevation with zero being sea level . mostly map use distance between coutour lines is 10 m
Answeeeeer:
A. cell
Explanation:
Since A is the smallest in the chart, that would correspond to the cell because thats the smallest out of Tissue, Organ and Organism.
Answer: 23 g
the mol of Fe is 11,5/56 = 23/112 (mol)
the mol of CO is
(mol)
we have:
Fe2O3 + 3CO => 2Fe + 3CO2
23/112 69/112 23/56
=> the mol of Fe is 23/56 mol
=> the mass of Fe is 23/56.56 = 23 (g)
Explanation:
This is percent composition
The formula for that is
(Mass of part/total mass) x 100
What’s the total molar mass of CO2?
12.01 +16(2) = 44.01 g/mol
What is the molar mass of Carbon?
Since there is only one carbon it is 12.01 g/mol
(12.01/44.01) x 100 = 27.29%
