yes
Ionic compounds generally have higher melting and boiling points.
Covalent bonds do not melt. Compounds with covalent bonds melt and the melting point depends primarily on whether there are discrete molecules held together by intermolecular forces (which have lower melting points) or giant covalent networks such as in silica or diamond (which tend to have higher melting points).
Ionic compounds generally have a higher melting point. This is because the bonds between the negative and positive ions are strong, and this keeps the solid together as the temperature rises. Covalent compounds have comparatively weak bonds between the molecules, so as the temperature rises, these bonds are broken easily and the substance turns into a liquid.
Factors affecting the solubility:1. the nature of solute/solvent (chemical composition, polarity)2. temperature3. pressure4. stirring5. surface area of the solute6. some added compounds7. amount of the solute 8. the geometry of the beaker
Yes, metals can melt in a home fire if the fire reaches temperatures high enough to exceed the melting point of the metal. The melting point of different metals varies, with some requiring higher temperatures to melt than others. Items made of materials with lower melting points, such as aluminum, may be more likely to melt in a typical home fire compared to those made of materials with higher melting points, like steel.
yes, for the same molecule. However, some substances don't have a liquid phase and so the melting point is exactly the same as the boiling point at normal pressures (sublimation is the phase change from solid -> gas)
Because they have interlocking electrons as the different elements' electrons have been 'tangled'
Some common properties of organic compounds include having covalent bonds, containing carbon and hydrogen atoms, being flammable, having low melting and boiling points, and often having a complex molecular structure.
Ionic compounds generally have higher melting and boiling points.
Compounds bonded by covalent bonds do not necessarily have low melting points. Some have whereas some don't have.Some polymers and hydrocarbons have very high melting points. But it can be said that they don't have melting points as high as ionic compounds. It is so because ionic bonds are stronger than the covalent bonds.

False, all minerals DO NOT have the same melting point

Elements have fixed melting and boiling points, while compounds have varying melting and boiling points depending on their composition. Mixtures do not have fixed melting and boiling points, as they are composed of multiple substances which each have their own individual melting and boiling points.

There are two molecular network structures that result in high melting points. The covalent structure of carbon forms rigidity of diamond. A diamond can in fact boil but it requires an extreme temperature because of this structure. Salt (NaCl) has a rigid ionic lattice structure between its sodium and chloride atoms. This gives salt a melting point of some 801 degrees Celsius.
