Oxana [17]
Answer is: f<span>ormula for the hydrated compound is CuSO</span>₄·3H₂O.
ω(H₂O) = 25,3% = 0,253.
ω(CuSO₄) = 100% - 25,3%.
ω(CuSO₄) = 74,7% = 0,747.
ω(H₂O) : M(H₂O) = ω(CuSO₄) : M(CuSO₄).
0,253 : M(H₂O) = 0,747 : 159,6 g/mol.
M(H₂O) = (0,253 · 159,6 g/mol) ÷ 0,747.
M(H₂O) = 54 g/mol.
N(H₂O) = 54 g/mol ÷ 18 g/mol.
N(H₂O) = 3.

What may cause some short term environmental changes how would organisms respond to these changes
jolli1 [7]

Answer:

Refer to explanation

Explanation:

Weather is the main cause behind most short term environmental changes

For example, a period of heavy rain may lead to a pond overflowing, and flooding the nearby shrubbery

Animals in the area would adapt to this by trying to keep away from the flooded area until it dries out, once the rain ends
