Answer:
Final temperature = 6.00 °C
Explanation:
The expression for the calculation of the enthalpy change of a process is shown below as:-
Where,
is the enthalpy change
m is the mass
C is the specific heat capacity
is the temperature change
Thus, given that:-
Mass of water = 200.0 g
Specific heat = 4.18 J/g°C
Let final temperature be x °C
= -11.7 kJ (Negative sign as heat is lost)
Also, 1 kJ = 1000 kJ
= -11700 J
So,
Final temperature = 6.00 °C
Answer:
Diastereomers can have different physical properties and reactivity. They have different melting points and boiling points and different densities.
Answer:
elements on the left-hand side of the periodic table such as sodium and magnesium prefer to lose electrons to form a cation because this requires less energy to obtain a stable octet, and vice-versa for the right-hand side of the periodic table e.g. fluorine. However, using this reasoning I am not sure why all transition metals tend to lose electrons rather than gain them.
Answer:
The law of reflection states that the angle of incidence and the angle of reflection are always equal.
