These characteristics are possessed by molecular solids. Examples of molecular solids are hydrocarbons. The atoms are bonded by relatively weak intermolecular forces like dipole forces. Hence, they easily melt. When dissolved in water, they don't dissociate and form ions unlike ionic solids. Therefore, they don't conduct electricity whether in solid or liquid form.
can turn on and off because it is active through an electric current and when the current is gone it no longer works . electromagnets<span>, - devices that create a magnetic field through the application of electricity. Wrecking yards employ extremely powerful electromagnets to move heavy pieces of scrap metal or even entire cars from one place to another. Your favorite band uses electromagnets to amplify the sound coming out of its speakers. And when someone rings your doorbell, a tiny electromagnet pulls a metal clapper against a bell.</span>
I will try to do it but not more than 70.4
Answer:
14 J of heat
Explanation:
Recall that the enthalpy of reaction is defined as the enthalpy change that occurs in a system when matter is transformed by a given chemical reaction, if all reactants and products are in their standard states. Here we have the heat of formation of six moles of the substance and we are expected to use it to obtain the the heat of formation of one mole of the compound and we can do that by simple proportion as shown below;
If 6 moles of the compound produces 84J of heat
1 mole of the substance will produce 1×84/6 = 14 J of heat
