Answer: K+ and P 3−
Explanation:
Electrostatic force of attraction is the attraction between different molecules that comes from them being electrically charged.
For molecules to have an electrostatic force of attraction, they need to have opposing charges because like charges repel each other but opposite charges attract.
In the question above, the only option that has opposing charges is option D so this is the correct option.
Answer:
The new temperature is 894 K or 621 °C
Explanation:
Step 1: Data given
Initial volume of the container = 2.000L
Initial temperature = 25.0 °C = 298 K
Volume increased to 6.00 L
Step 2: Calculate the new temperature
V1/T1 = V2/T2
⇒with V1 = the initial volume = 2.00L
⇒with T1 = the initial temperature = 25 °C = 298 K
⇒with V2 = the increased volume 6.00 L
⇒with T2 = the new temperature
2.00 L / 298 K = 6.00 L / T2
T2 = 894 K = 621 °C
The new temperature is 894 K or 621 °C
