Answer:
The correct answer is 1.21 L.
Explanation:
Based on the given information, the reaction will be,
CS2 (l) + 3Cl2 (g) ⇒ CCl4 (l) + S2Cl2 (l)
By using the standard values of the substances, the standard enthalpy of the reaction is,
ΔH° = [(-139.5) + (-58.5) – 0 – (87.3)] kJ/mol
= -285.3 kJ/mol
The amount of heat evolved for 3 moles of chlorine reacted us 285.3 kJ.
Now the number of moles of chlorine needed to react to produce 5.00 kJ is,
= 5.00 kJ × 3 mol Cl2/285.3 kJ
= 0.0526 mol Cl2
Now the volume of chlorine gas at 27degree C and 812 mmHg will be,
Volume = 0.0526 mol Cl2 × 0.0821 Latm/mol K × 300 K/ 1.07 atm
= 1.21 L
Answer:
1.006 * 103
Explanation:
Add the number between 1 and 9 and add a decimal accordingly . so the answer is 1.006 multiplied by 10 raised to power 3
Answer:
Adding enough thermal energy to a substance can cause a change of state to occur. The change of state from a solid to a liquid is called melting. When energy is added to an ice cube, the ice particles speed up as energy is absorbed. When the particles move fast enough, the solid ice melts and becomes liquid water
Answer:
Mg+2HCL-Magnesium Chloride +Hygrogen
Explanation:
N.O of moles=Mass\Molar Mass
192÷24=8
1:1
8×2=16
Sorry but I only know a few
17- decomposers
18- decomposition
21- 10% is lost so 90%
