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: Major scale and minor scale both relate the precision of measurements with more true value of measurement.
Explanation:
Major scale in a measuring device is maximum unit value on the scale that can be measured.
Minor scale in a measuring device is a least unit value on the scale that can be measured.
In a metric ruler major scale is 1 cm and minor scale is 0.1 mm which means one can measure accurate value up-to one decimal point and in 10 ml of graduated cylinder major scale division is 1 ml minor scale division is 0.01.
I think the reason why the reaction is at equilibrium after 60 seconds is because the concentration of both NO2 and N2O4 are : Constant, which means that they do not undergone any change

Answer:
they use echos to communicate
Explanation: dolphins make echos in order to signal there partners, and others in there pod. or they can use it to signal for prey, or signal that they are in trouble.
Answer:Examples of tipping points are everywhere: a glass falling off a table upon tilting; a bacterial population hitting a level where it pushes your body into fever; the boiling point of water, or a cube of ice being thrown into warm water, where it rapidly melts.
