Answer:
Sorry that I'm late but the correct answers are to dissolve the political bonds between Louisiana and the united states and to declare that Louisiana was a free and independent state, or D and E
Explanation:
Answer:
<h3>The answer is 400 mL</h3>
Explanation:
The new volume can be found by using the formula for Boyle's law which is

where
P1 is the initial pressure
P2 is the final pressure
V1 is the initial volume
V2 is the final volume
Since we are finding the new volume

So we have

We have the final answer as
<h3>400 mL</h3>
Hope this helps you
Answer:
E. All of the above are true.
Explanation:
<em>Which of the following statements is TRUE?</em>
<em>A. State functions do not depend on the path taken to arrive at a particular state.</em> TRUE. State functions like enthalpy (ΔH) and internal energy (ΔE) do not depend on the trajectory, but on the initial and final state.
<em>B. Energy is neither created nor destroyed, excluding nuclear reactions.</em> TRUE. Only in nuclear reactions can energy (E) can be transformed in matter (m) and vice-versa according to Einstein equation: E = m . c² (c is the speed of light).
<em>C. ΔHrx can be determined using constant pressure calorimetry.</em> TRUE. The enthalpy of reaction is the heat involved at constant pressure.
<em>D. ΔErx can be determined using constant volume calorimetry.</em> TRUE. The internal energy of reaction is the heat involved at constant volume.
<span>Kinetic energy is the energy of mass in motion. The kinetic energy of an object is the energy it has because of its motion. ... When we double the mass, we double the energy; however, when we double the velocity, energy increases by a factor of four.</span>
