Answer: 1560632 joules
Explanation:
The change in thermal energy (Q) required to heat ice depends on its Mass (M), specific heat capacity (C) and change in temperature (Φ)
Thus, Q = MCΦ
Given that:
Q = ?
Mass of frozen water (ice) = 1kg
C = 4184 J/(kg K)
Φ = (Final temperature - Initial temperature)
= 100°C - 0°C = 100°C
Convert 100°C to Kelvin
(100°C + 273) = 373K
Then, Q = MCΦ
Q = 1kg x 4184 J/(kg K) x 373K
Q = 1560632 joules
Thus, the change in thermal energy is 1560632 joules

Option a: alkene
Styren is C6H5CH=CH2, i.e. ethenylbenzene
Answer:
Instensive physical properties
Explanation:
bc they don't depend the amount of matter in the substance
1.5 L KNO3 solution* (2.0 mol KNO3/ 1 L KNO3 solution)= 3.0 mol KNO3.
The correct answer is (3) 3.0 mol.
Hope this would help~
