Answer:
the squid population could decrease, because the tuna population is increasing and they would eat more squid, so the dolphin population would also decrease because there would be less squid to eat, and because there are less squid the herring population would increase.
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
Mg is magnesium. NO3 is nitrate. This gives you magnesium nitrate as an answer.
Answer:
One cubic centimeter is equal to one milliliter. Cubic centimeter is used interchangeably with millimeter. Centimeter belongs in the CGS unit system (centimeter-gram-second system) while liter belongs in the SI (Système International d'Unités) unit system. These two are equal.
Explanation:
Each energy sub-level corresponds to an orbital of a different shape which describes where the electron is likely to be found
