The heat is added to 200g ice at 0ºC to make the ice become water. there is no increase in temperature. the heat added is equal to the number of moles of ice melted x molar heat of fusion of ice, 6.01kJ/mole.
<span>200g / 18g/mole = 11.11moles ice </span>
<span>11.11moles x 6.01kJ/mole = 66.78 kJ heat just to melt the ice to water </span>
<span>if you are just looking for the heat to melt the sample of ice, this is where you stop. </span>
<span>if you need to determine the heat to melt the ice AND raise the temperature, this is what you require </span>
<span>the second phase is raising the temperature of the water to 65ºC. this is equal to the mass of the water x specific heat of water x change in temperature </span>
<span>200g x 4.187J/g-ºC x 65ºC = 54431J or 54.431kJ energy to raise the water from 0ºC to 65ºC </span>
<span>the total heat required to melt the ice and then raise the temperature to 65ºC: </span>
<span>66.78kJ + 54.431kJ = 121.21kJ heat</span>
The answer is: Ammonium hydroxide would be found in the pantry because it is found in vinegar.
Ammonim hydroxide (NH₄OH) is base and vinegar is acid.
pH of ammonium hydroxide is greater than 7 and vinegar has pH less than 7.
Ammonium hydroxide is a smelling, colorless liquid.
It is used as cleaning product, disinfectants and stain treaters.
Household ammonia contains 5-10% ammonium hydroxide.

Answer:
Ionic compounds are compounds whereas metals are elements. Ionic compounds are electrolytes whereas metals are conductors. Ionic compounds are brittle whereas metals are malleable and ductile. ... Most ionic compounds will dissolve in polar solvents like water whereas metals will either be insoluble or react with water.
