The answer to this question is A.) Salad
Answer:
The answer to your question is: letter C
Explanation:
a. the sharing of electrons between a hydrogen atom and another atom. This description is not for hydrogen bonding, in hydrogen bonding atoms do not share electrons, to form this bond.
b. the electrostatic interaction between an atom that has lost an electron and an atom that has gained an electron. This definition is describing an ionic bonding, not a hydrogen bonding.
c. the interaction between a hydrogen atom covalently bonded to an electronegative atom and another electronegative atom. This is the right definition of hydrogen bonding, because is mentioning the interaction between a hydrogen and an electronegative atom.
It is possible to have experiments in which you have multiple variables.
Answer:
The difference between alchemy and modern chemistry is alchemy is based on a mystic, supernatural view of reality, whereas chemistry assumes reality is basically natural.

2NaCN(s) + H₂SO₄(aq) --> Na₂SO₄(aq) + 2HCN(g)
The molar ratio between NaCN : HCN is 2:2 or 1:1
Mass of HCN = 16.7 g
Molar mass of HCN = 1 + 12 + 14 = 27 g/mol
Molar mass of NaCN = 49 g/mol
Therefore, the mass of NaCN is
16.7 g of HCN x 49 g/mol of NaCN / 27 g/mol of HCN = 30.3 grams of NaCN
Therefore, 30.3 grams of NaCN gives the lethal dose in the room.
