Another type of weathering that attacks rocks is chemical weathering, a process that breaks down rock through chemical changes. The causes of chemical weathering include action of water, oxygen, carbon dioxide, living organisms, and acid rain. Chemical weathering can produce new minerals as it breaks down rock.
Explanation:
Answer:
2200 g
Explanation:
Data Given:
no. of moles of Ba₃N₂ = 5 moles
mass of Ba₃N₂ = ?
Solution:
Formula used
no. of moles = mass in grams / molar mass
To find mass rearrange the above equation:
mass in grams = no. of moles x molar mass. . . . . . (1)
molar mass of Ba₃N₂
molar mass of Ba₃N₂ = 3(137.3) + 2(14)
molar mass of Ba₃N₂ = 412 + 28
molar mass of Ba₃N₂ = 440 g/mol
Put values in equation 1
mass in grams = 5 moles x 440 g/mol
mass in grams = 2200 g
So,
mass of Ba₃N₂ = 2200 g
Osmium is the densest<span> element on earth. It is a hard, weak, pale blue white move metal in the platinum aggregate that is found as a follow component in amalgams, generally in platinum minerals. Osmium is the densest normally happening component, with a thickness of22.59 g/cm3. There is still some open deliberation that Iridium is the denser component as per hypothetical figurings yet starting at now, Osmium has the most noteworthy measured thickness. </span>
B is the correct answer if I remember
