Ageographical area where plants, animals, the landscape, and the climate all interact together is called a(n)

environment
ecosystem
biome
food web

Actually, the correct answer is an ecosystem. Which is an area where plants, animals, the landscape, and climate all interact together.

This is correct because in an ecosystem, all forms of the environment, which includes living things and nonliving things, interact and affect one another.

"you start with 15.67 g mgco3-xh2o, when heated and all the water is removed, you are left with 7.58 g mgco3 only.

therefore, you had 15.67 - 7.58 = 8.09g h2o  

moles of each :

7.58g mgco3 = ? moles = 7.58g / 83.4g/mole = 0.09moles  

8 09g h2o = ? moles = 8.09g / 18g/mole = 0.44moles  

molar ratio between the two by dividing both numbers by the smallest number :

0.09 / 0.09 = 1  

0.44 / 0.09 = 4.8
