Answer:
The value of the heat capacity of the Calorimeter 
= 54.4 
Explanation:
Given data
Heat added Q = 4.168 KJ = 4168 J
Mass of water 
= 75.40 gm
Temperature change = ΔT = 35.82 - 24.58 = 11.24 ° c
From the given condition
Q = 
ΔT + ΔT
Put all the values in above equation we get
4168 = 75.70 × 4.18 × 11.24 + × 11.24
611.37 = × 11.24
= 54.4
This is the value of the heat capacity of the Calorimeter.
This doesn’t seem like the full question
Strontium, Calcium, Magnesium
Strontium is the most reactive of the three element because of this, it does not exist free in nature but rather exist in combination with other elements in various compounds such as strontianite. Calcium is more reactive than magnesium because it is larger than magnesium and thus, it is more electropositive in nature.
Answer:
hi
Explanation:
There is enough energy in air at room temperature to change some liquids to gases. The temperature of ice water is lower than the temperature of dry ice in alcohol. Carbon dioxide can change directly from the solid phase to the gaseous phase. ... Absolute zero is the temperature at which there is no molecular motion.
