It's true because gravity retract everything.
Answer:
Based on my EXPLAIN i think the answer is C.
Explanation: A chemical reaction is a process that leads to the chemical transformation of one set of chemical substances to another. Classically, chemical reactions encompass changes that only involve the positions of electrons in the forming and breaking of chemical bonds between atoms, with no change to the nuclei (no change to the elements present), and can often be described by a chemical equation. Nuclear chemistry is a sub-discipline of chemistry that involves the chemical reactions of unstable and radioactive elements where both electronic and nuclear changes can occur.
The salt bridge prevents the direct mixing of one half-cell solution with the other and allows ions to migrate from one half-cell to another.
Answer:
Explanation:
Hello!
In this case, since the heat involved during a heating process is computed in terms of mass, specific heat and temperature change as shown below:
Thus, since the heated mass of water was 88 g, the specific heat of water is 4.184 J/g°C and the temperature change is 6.0 °C, we can compute the heat as shown below:
Best regards!
Density=mass/volume. Put the mass (2790g) over the volume (205mL)
Density= 2790g/205mL
Your answer should be in g/mL.
Hope this helped! :)
