In combustion energy is released so it is an exothermic process !!
the answer is 2nd one !!
Answer:
A, C, and D
Explanation:
The correct options that apply to the principal conservation of energy are A, C, and D.
A is correct because energy can neither be created nor destroyed. However, energy can be transfered from one location to another or be converted from one form to another. <em>Whether transferred to converted, the magnitude remains the same.</em>
C is correct because energy cannot be destroyed but can be transferred or converted. <em>Hence, if a body or a location loses temprature, then the loss is being gained by another body or location.</em>
D is also correct. A closed system is a system that does not exchange matter with its surroundings. <em>Hence, the total energy remains the same within the system. </em>

Answer:
The answer to your question is 1.83 x 10²⁵ particles
Explanation:
Data
particles of H₂O = ?
mass of H₂O = 546 g
Process
1.- Calculate the molar mass of Water
Molar mass = (2 x 1) + (1 x 16)
= 2 + 16
= 18 g
2.- Use proportions to find the number of particles. Use Avogadro's number.
18 g ---------------- 6.023 x 10²³ particles
546 g --------------- x
x = (546 x 6.023 x 10²³) / 18
3.- Simplification
x = 3.289 x 10²⁶ / 18
4.- Result
x = 1.83 x 10²⁵ particles
