Hello there!
In this case, according to the given information, it turns out firstly necessary for us to set the equation for the calculation of density and mass divided by volume:
Thus, we can find the mass of the unknown by subtracting the total mass of the liquid to the mass of the flask and the liquid:
So that we are now able to calculate the density in g/mL first:
Now, we proceed to the conversion to lb/in³ by using the following setup:

Answer:
Sound waves required a medium.
Explanation:
In space, there is only vacuum hence no any medium for sound wave travel.
Since sound waves are mechanical waves, they require a material medium such as air, hence no sound transmission.
Answer:
2 Cu2O + C → 4 Cu + CO2
This is an oxidation-reduction (redox) reaction:
4 CuI + 4 e- → 4 Cu0 (reduction)
C0 - 4 e- → CIV (oxidation)
Cu2O is an oxidizing agent, C is a reducing agent.

Answer:
Explanation:
when dissolved in water, dissociates into ions, including hydrogen ions. According to Arrhenius, an acid can be defined as a material that increases the concentration of hydrogen ions in water.
I believe the answer is A.
