There are 6.022×1023 molecules in one mole of glucose so you would just divide this number by 100 and multiply the result by 54 which would leave you with 3326.67324 molecules in 0.54 moles of glucose
Atoms don't undergo a change in state during phase change. In fact phases or states can only be defined for groups of atoms. It is the energy state of these groups of atoms that decides the state and defines temperature.
<span>In the process of evaporation molecules at the surface of the liquid gain higher energy when they are 'hit' with molecules of the gas surrounding it during their constant Brownian motion which gives it the energy to break away from the surface. This happening over a large scale of the liquid surface is what is evaporation.</span>
Answer:
is tht wht u want
Explanation:
1 grams Sodium is equal to 0.043497607849056 mole.
Number #2 is joule
In the SI system the unit of heat is the joule. The calorie was defined so that the heat capacity of water was equal to one.The heat capacity of a substance is the amount of heat required to raise the temperature of a defined amount of pure substances by one degree.
Number #3 is Endothermic
Why? I can't explain. I Just left class where they were just explaining that.
Answer:
When the Zebra arrived they ate all the food so the Unionid mussels declined as they died from the lack of food. Causing the Zebra Zebra numbers to increase and Unionid numbers to decline.
