Answer:Hummingbirds have long, needlelike beaks they use to probe deep into flowers. The hummingbird's beak is just a protective sheath for its tongue, which is actually what the hummingbird is using to get the nectar out of the flower. The tip of their tongue is forked and has little hairs all over it.
Explanation:
Answer:
1.22 x 10²⁵ molecules CO₂
Explanation:
To find the amount of molecules, you need to multiply the number of moles by Avogadro's Number. Avogadro's Number is a ratio which represents the amount of molecules per every 1 mole. It is important to arrange this ratio in a way that allows for the cancellation of units (since you are going from moles to molecules, moles should be in the denominator). The final answer should have 3 sig figs like the given value.
Avogadro's Number:
6.022 x 10²³ molecules = 1 mole
20.2 moles CO₂ 6.022 x 10²³ molecules
--------------------------- x -------------------------------------- = 1.22 x 10²⁵ molecules
1 mole
