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
Emest Rutherford proved that the plum pudding model was incorrect then he experimented by firing cathode rays at gold foil.
Metals are the majority of the periodic table. Also, they are on the left side of the periodic table. The no metals are on the right side of periodic table.

The answer is both are made of cells that contain a nucleus. Since they made up of cells that have a nucleus enclosed within membranes, bees and flowers can be classified under Domain Eukarya. Animals are heterotrophic, have no cell walls and no cloroplasts, while plants are autotrophic, have cell walls with cellulose and have chloroplasts.
