Answer:
-81.5 degrees C or 191.5 K
Explanation:
We want to use Charles' gas law: V/T = V/T
Our initial volume is 3.20 L, and our initial temperature is 125 degrees C, or 125 + 273 = 398 degrees Kelvin.
Our new Volume is 1.54 L, but we don't know what the temperature is. So, we use the equation:
3.20 L / 398 K = 1.54 L / T ⇒ Solving for T, we get: T = 191.5 K
If we want this in degrees Celsius, we subtract 273: 191.5 - 273 = -81.5 degrees C
Answer:
3NaOH + H3PO4 ---> 3H2O + Na3PO4
Explanation:
You would first do research. (d)
The research part will help you find what ideas worked and what ideas didn't work.
1) gain
(just remember this OIL-Oxidation Is Loss and RIG-Reduction Is Gain)
2) decrease
