It is correct, next time re-check your answer and don't second guess yourself. ;3
14 since K has 1 valence but there’s two so 2 valence for k and oxygen has 6 but there’s two so 12
Explanation:
Safety hazards means they are are the unsafe working conditions which can cause the workmen injury, illness, or death. Safety hazards are some of the most common risks at the workplace.
Electrical hazards may be defined as a place or a condition which is dangerous and where a person working can come in contact with electrical contact with some energized equipment or any electrical conductor.

The safety steps are :
1. Follow the instruction properly
2. Take proper safety measures like wearing gloves, shoes, not touching any live wires, etc.
3. Follow the clean up procedure properly.
Answer:
The work done on the system is 17.75_KJ
Explanation:
To solve this question we need to know the required equations from the given variables, thus
Initial volume = 85L
Final volume = 12L
External pressure = 2.4 atm.
work done = - PΔV
2.4×(85-12) = 175.2L×atm
Converting from L•atm to KJ is given by
1 L•atm = 0.1013 kJ
(175.2 L•atm) * (0.1013 kJ / 1 L•atm)
= 17.75 kJ
The work done on the system is 17.75_KJ
the volume will be 0.84mol of Y
