Answer:
Chemical reactions involve breaking chemical bonds between reactant molecules (particles) and forming new bonds between atoms in product particles (molecules). The number of atoms before and after the chemical change is the same but the number of molecules will change.
Explanation:
Answer:
The final temperature at 1050 mmHg is 134.57 
or 407.57 Kelvin.
Explanation:
Initial temperature = T = 55 = 328 K
Initial pressure = P = 845 mmHg
Assuming final to be temperature to be T' Kelvin
Final Pressure = P' = 1050 mmHg
The final temperature is obtained by following relation at constant volume
The final temperature is 407.57 K
