Answer:
ammonia gas and hydrogen chloride gas.
<h2>Answer:</h2>
<u>The right option is</u><u> (C) intermediate conductivity and a high melting point</u>
<h2>Explanation:</h2>
Metalloids usually look like metals but behave largely like nonmetals. Metalloids are shiny, brittle solids with intermediate good electrical conductivity. Their properties lie between metals and non metals. All metalloids exist as solids at room temperature and they have very high melting points. The physical properties of metalloids are more likely to be metallic, but their chemical properties tend to be non-metallic
Intermolecular bonding:
Water is a polar molecule exhibit dispersion forces and hydrogen bonding
Salt is a polar molecule exhibit dispersion forces and dipole dipole bonding
Same bonding capacity therefore similar bonding capacity, therefore salt able to dissolves in water
Answer:
C
