0.77 moles of aluminum nitrate can be found when 21g of aluminum react with lead (II) nitrate.
<h3>Equation of reaction</h3>
- Al + Pb(NO₃)₂ ---> Al(NO₃)₃ + Pb (s)
From the equation of reaction:
1 mole of aluminum reacts with 1 mole of lead nitrate to produce 1 mole of aluminum nitrate
1 mole aluminum has a mass of 27 g
Number of moles of aluminum in 21 g = 21/27 =0.77 moles
0.77 moles of Aluminum produces 0.77 moles of aluminum nitrate
Therefore, 0.77 moles of aluminum nitrate can be found when 21g of aluminum react with lead (II) nitrate.

Answer:
A niche is more than a physical place; it's a species' role in a specific place and it can change from habitat to habitat.
Explanation:
Niche: In biology, the term "niche" is described as a process through which different organisms tends to fit-in into a specific ecosystem or an ecological community. However, a niche is considered as the "evolutionary result" of a specific species behavioral, morphological, and physiological adaptations associated with its surroundings.
Habitat: In biology, the term "habitat" is described as an environmental or ecological area that is being inhabited by a specific species of plants, animals, or other organisms.
Therefore, a niche is entirely different from a habitat because an organism's niche tends to explain every different aspect of its life whereas its habitat explains the place it lives.
Answer:
just watch the video, what does it start with, write that down for each trial, then what does it end with, then starting mass - ending mass is the change mass
