Answer : The amount of heat released, -35057 J
Solution :
Process involved in the calculation of heat released :
![(1):H_2O(g)(100^oC)\rightarrow H_2O(l)(100^oC)\\\\(2):H_2O(l)(100^oC)\rightarrow H_2O(l)(25^oC)](https://tex.z-dn.net/?f=%281%29%3AH_2O%28g%29%28100%5EoC%29%5Crightarrow%20H_2O%28l%29%28100%5EoC%29%5C%5C%5C%5C%282%29%3AH_2O%28l%29%28100%5EoC%29%5Crightarrow%20H_2O%28l%29%2825%5EoC%29)
Now we have to calculate the amount of heat released.
where,
Q = amount of heat released = ?
m = mass of water = 18 g
= specific heat of liquid water =
= enthalpy change for condensation = -40700 J/mole
Now put all the given values in the above expression, we get
![Q=-35057J](https://tex.z-dn.net/?f=Q%3D-35057J)
Therefore, the amount of heat released, -35057 J
Explanation:
A point of temperature at which both solid and liquid state of a substance remains in equilibrium without any change in temperature then this temperature is known as melting point.
For example, melting point of water is
. So, at this temperature solid state of water and liquid state are present in equilibrium with each other.
Therefore, when a 100 g of given pure metal in solid state is heated at its exact melting point which is
then some of the solid will change into liquid state but the temperature will remains the same.
Answer:
A a mountain
Explanation:
this is becuase the two plates are pushing into each other, so all that rock will go where theres the least resistance, up
you can see this when you place your hands (palms down facing each other where the tis touch) on a table or flat surface, if you slowly bring them together ((DONT DO IT HARD OR FAST else u may hurt urself)) your fingertips will begin to want to rise up
the answer is not B becuase:
a canyon is formed when erosion carves into the earth, this oes NOT need to happen at a fault line and deffinitally does not happen n converging plates as shown
the answer is not D becuase:
a ridge is formed when ne plate pushes under the other, pushing that second plate upward, when this happens it forms a chain of mountains, though this is simmilar to the correct answer, the diagram does not show the plates undernieth one another, rather they are pushing against each other
the answer is not C becuase:
a fault is where two plates are moving away from each other, creating a canyon like structure, this is not a canyon however, for it is not formed by erosion, most faults can be found underwater since oceans usually fill in the gap where rock used to be
hope this helps you, sorry if its a lot of reading ^^"
In their chemical formula, Calcium Nitrate is Ca(NO₃)₂ while Sodium Hydroxide is NaOH. The reaction between the two are:
Ca(NO₃)₂ + 2 NaOH → Ca(OH)₂ + 2 NaNO₃
As you can see, this is a double replacement reaction. Focusing on the products, in an aqueous solution, NaNO₃ will dissolve in water because all nitrates are soluble. Ca(OH)₂ is insoluble in water so this is the solid that precipitates.
