Refer to the activity series chart and determine which of the following displacement reactions can occur. A.
2Ag(s) + Zn(NO3)2(aq) → 2AgNO3(aq) + Zn(s)

B.
2Cu(NO3)2(aq) + 2Ag(s) → 2AgNO3(aq) + Cu(s)

C.
CuSO4(aq) + Fe(s) → FeSO4(aq) + Cu(s)

D.
3MgSO4(aq) + 2Al(s) → Al2(SO4)3(aq) + 3Mg(s)

Why is the vapor pressure of a warm lake higher than the vapor pressure of a cold lake? o a. warm water has a greater heat of vaporization. ob. warm water evaporates more quickly. cool water evaporates more quickly. od. cool water has a greater heat of vaporization.

Why do you suppose the structural polysaccharide cellulose does not contain branches? why do you suppose the structural polysaccharide cellulose does not contain branches? branches in the molecule would generate side chains that would almost certainly make it difficult to pack the cellulose molecules into globules, thereby decreasing the flexibility and strength of the globules. branches in the molecule would generate side chains that would almost certainly make it difficult to pack the cellulose molecules into microfibrils, thereby increasing the rigidity and strength of the microfibrils. branches in the molecule would generate side chains that would almost certainly make it difficult to pack the cellulose molecules into globules, thereby increasing the flexibility and strength of the globules. branches in the molecule would generate side chains that would almost certainly make it difficult to pack the cellulose molecules into microfibrils, thereby decreasing the rigidity and strength of the microfibrils.

About 3% of the water on earth is freshest. only about 40% of that freshwater is available for human use. why is so much freshwater unavailable for human use?
