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>
I´m pretty sure its magnesium iron silicate.
OMG yessss that is so cute she will totally accept
Answer:
Herbivores would increase causing producers to decrease.
Explanation:
If the carnivores are gone, herbivores wouldn't get eaten and increase, and more herbivores mean less producers available.
