Answer : The correct Lewis-dot diagram is shown below.
Explanation :
Lewis-dot structure : Lewis-dot structure shows the bonding between the atoms of a molecule. Lewis-dot structure also shows the unpaired electrons present in the molecule. In the Lewis-dot structure, the dot represent the number of valence electrons.
The given molecule is, Hydrogen cyanide (HCN)
As we know that carbon has '4' valence electrons, hydrogen has '1' valence electron and nitrogen has '5' valence electrons.
Therefore, the total number of valence electrons in hydrogen cyanide, = 1 + 4 + 5 = 10
According to Lewis-dot structure, there are 10 number of bonding electrons and 0 number of non-bonding electrons.
The Lewis-dot structure of hydrogen cyanide (HCN) is shown below.
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):
