If you were a predator bird, which moth would be easier prey to hunt? Why?

Birds will frequently attack when the moths are at rest against a tree, which is why it is so crucial that the insect blends into its surroundings. It is much easier for birds to locate and prey on moths that do match the bark of the tree it is resting against, making it an easier target than a moth that does match.

here's the link to your question!

explanation:

"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  

mgco3-5h2o"
