Answer:
Land-use change: Humans may destroy natural landscapes as they mine resources and urbanize areas. This is detrimental, as it displaces residing species, reducing available habitats and food sources. ... This can negatively effect an ecosystem because the introduced species may outcompete native organisms and displace them.
Explanation:
Answer: 10
Explanation:
The detailed solution is contained in the image attached. The molar mass of hydrated and anhydrous salts are obtained and the number of moles of hydrated and hydrated salts are equated. The masses of hydrated and anhydrous salts are gives in the question and are simply substituted accordingly. This can now be used to obtain the number of molecules of water of crystallization as required in the question.
Answer:
0.080 M
Explanation:
From the question given above, the following data were obtained:
Concentration of H₂SO₃ = 0.080 M
Concentration of SO₃²¯ =…?
The concentration of SO₃²¯, can be obtained as follow:
H₂SO₃ (aq) <==> 2H⁺ (aq) + SO₃²¯ (aq)
From the balanced equation for above,
1 mole of H₂SO₃ produced 1 mole of SO₃²¯.
Therefore, 0.080 M H₂SO₃ will also produce 0.080 M SO₃²¯.
Thus, the concentration of SO₃²¯ is 0.080 M
