Answer:
Metallic structure
Explanation:
They have a high melting point due to the strong forces of attraction between the positive ions (cations) and the delocalised electrons. Moreover, they conduct electricity due to the sea of delocalised electrons.
<em>[Extra: It could be an ionic compound since they also have a high melting point, however they only conduct electricity in liquid or aqeouus state.]</em>
it will expand as water moves into it.
Azeotropic mixture. I think
Answer:
a. sulfur difluoride SF₂
b. sulfur hexafluoride SF₆
c. sodium dihydrogen phosphate NaH₂PO₄
d. lithium nitride Li₃N
e. chromium(III) carbonate Cr₂(CO₃)₃
f. tin(II) fluoride SnF₂
g. ammonium acetate NH₄(CH₃COO)
h. ammonium hydrogen sulfate NH₄(HSO₄)
i. cobalt(III) nitrate Co(NO₃)₃
j. mercury(I) chloride Hg₂Cl₂
k. potassium chlorate KClO₃
l. sodium hydride NaH
Explanation:
The names give us information about the composition. First, we mention the cation and then the anion. In the formula, we follow the same order. Each part has a charge but the resulting compound is electrically neutral.
