Answer:
i) 0,7 molH20/s
ii)11,2 g O/s
iii)1,4 g H/s
Explanation:
i) To find the molar flow rate of water, we just convert the mass of water to moles of water using its molecular weight(g/mol) and changing to the proper units (lb to grames and hours to seconds):
ii) Now we just consider the oxygen in the water stream (for 1 mole of water there is 1 mole of oxygen):
iii)Just considering the hydrogen in the stream (for 1 mole of water there is 2 moles of hydrogen):
Answer:
Explanation:
The solid consists of positive and negative ions, so it is an ionic solid.
Ionic solids are brittle, usually water-soluble, and poor thermal conductors as solids. Thus, the correct answer is .
(A) is wrong. It describes a covalent solid, which is soft and always a poor conductor.
(B) is wrong. It describes a covalent solid, which is also low-melting.
(D) is wrong. It describes a metal, and a metal does not contain negative ions.
