Answer is: mass of slaked lime is 6.92 grams.
Balanced chemical reaction: Ca(OH)₂ + 2NH₄Cl → CaCl₂ + 2NH₃ + 2H₂O.
m(NH₄Cl) = 10 g; mass of ammonium chloride.
M(NH₄Cl) = 14 + 1·4 + 35.5 · g/mol.
M(NH₄Cl) = 53.5 g/mol; molar mass of ammonium chloride.
n(NH₄Cl) = m(NH₄Cl) ÷M(NH₄Cl).
n(NH₄Cl) = 10 g ÷ 53.5 g/mol.
n(NH₄Cl) = 0.187 mol; amount of ammonium chloride.
From balanced chemical reaction: n(NH₄Cl) : n(Ca(OH)₂) = 2 : 1.
n(Ca(OH)₂) = 0.093 mol.
m(Ca(OH)₂) = n(Ca(OH)₂) · M(Ca(OH)₂).
m(Ca(OH)₂) = 0.093 mol · 74.1 g/mol.
m(Ca(OH)₂) = 6.92 g.

Answer:
Human activity is by far the biggest cause of habitat loss.
Humans are now responsible for causing changes in the environment that hurt animals and plant species. We take up more space on Earth for our homes and cities. We pollute habitats. ... Human activity often changes or destroys the habitats that plants and animals need to survive.
Explanation:
Human activities are the various actions for recreation, living, or necessity done by people. For instance it includes leisure, entertainment, industry, recreation, war, and exercise.
Over time, destruction of such habitats leads to reduced biodiversity, weakening the Earth's ecosystems, and ultimately posing a major threat to human life. While, significant tracts of habitat have been lost, and along with them many species of plant and animal, steps can be taken to slow and even reverse the process.
One of the most significant ways in which humans have impacted on the lives of other species is by causing climate change. Many animals, including birds and frogs, now breed much earlier in spring in Britain than they did 20 years ago. Whether or not this is having a harmful effect on them has yet to be determined.
Answer: hey so I’m taking the same test as you right now. I’m on that question and I searched it up and came on here. Would you mind telling me the answer?
