Answer:
Explanation:
<u>Given Data:</u>
Initial Volume = 
= 7.0 L
Initial Temperature = 
= 300 °C + 273 = 573 K
Final Temperature = = 25.0 °C + 273 = 298 K
<u>Required:</u>
Final Volume = 
= ?
<u>Formula:</u>
<u>[Charles Law] </u>
<u>Solution:</u>
Put the givens
![\displaystyle \frac{7}{573 } =\frac{V_2}{298} \\\\0.01 = \frac{V_2}{298} \\\\\times 298 \ to \ both \ sides\\\\0.01 \times 298 = V_2\\\\3.64 \ L =V_2\\\\\boxed{V_2 =3.64 \ L}\\\\\rule[225]{225}{2}](https://tex.z-dn.net/?f=%5Cdisplaystyle%20%5Cfrac%7B7%7D%7B573%20%7D%20%3D%5Cfrac%7BV_2%7D%7B298%7D%20%5C%5C%5C%5C0.01%20%3D%20%5Cfrac%7BV_2%7D%7B298%7D%20%5C%5C%5C%5C%5Ctimes%20298%20%5C%20to%20%5C%20both%20%5C%20sides%5C%5C%5C%5C0.01%20%5Ctimes%20298%20%3D%20V_2%5C%5C%5C%5C3.64%20%5C%20L%20%3DV_2%5C%5C%5C%5C%5Cboxed%7BV_2%20%3D3.64%20%5C%20L%7D%5C%5C%5C%5C%5Crule%5B225%5D%7B225%7D%7B2%7D)
<span>Sodium carbonate (Na2CO3) reacts with acetic acid (CH3COOH) to form sodium acetate (NaCH3COO), carbon dioxide (CO2), and water (H2O). A chemist carries out this reaction in a bomb calorimeter. The reaction causes the temperature of a bomb calorimeter to decrease by 0.985 K. The calorimeter has a mass of 1.500 kg and a specific heat of 2.52 J/g K. What is the heat of reaction for this system? What equation should I use in this case? I've written down these notes: Steps: 1. Calculate the mass of the solution in total. 2. Convert mass to volume or vice versa if needed. 3. Calculate the temperature change of the solution. 4. Calculate the energy released by the reaction.</span>
The main chemical compound cells use for energy is Adenosine Triphosphate (ATP)
Answer:
nothing
Explanation:
Here no result have been found yet..
Therfore we cannot determine which variable is dependent and which is not
They are classified by similar properties and number of valence electrons and energy levels
