Well even though im not giving you the whole answer, Im going to tell you what to do in order for you to do it. The main thing you need to do is to determine the delta H and delta S for the reaction.<span>Then subtract the reactants from the products.
On eexample of this is: </span><span>Delta H = (-634.9(CaO)+-393.5(CO2)) - (-1207.6 (CaCO3)) = 179.2 kJ
</span><span>Do the same thing for Delta S but make sure you use the correct units. Delta S is in Joules so you may need to convert. Once you have those values, plug into the equation
</span><span>Delta G= Delta H - T * Delta S
</span>And you will get your result
hope this is very useful for you
Answer:
technology that detects radio waves identified a pulsar at the center of the nebula
Explanation:
Crab nebula(M1) is a blob-like patch which is supernova remnants as far as Constellation of Taurus is concerned.
It has apparent magnitude of 8.4 and can only be viewed by telescope. The astronomers make use of technology that detects radio waves, which identified a pulsar at the center of the nebula, this pulsar is a magnetized rotating compact star which is known with it's electromagnetic emissions.
We know, mole of gas in ideal conditions is 22.414 L
Here, CH4 volume = 8.9L
So, number of moles = 8.9 / 22.414 = 0.397 moles
Here, in balanced equation we have a ratio CH4 : H2O = 1:2.
So, mole so water = , 0.397*2= 0.794 moles
In liters it would be: 0.794 * 22.414 = 17.80 L
In short, Your Answer would be 17.80 Liters
Hope this helps!
Answer:
False, since boiling is a physical change of state. Although it is at 100°C, it is not a chemical property.
Explanation:
Hope this helped!
Fluorine ions reacts with Hydrogen chloride to form more hydrogen fluoride.
Therefore, moles of HCl = 0.005 l × 0.01 M = 5 ×10^-5 moles
The initial moles of Hydrogen fluoride will be;
= 0.0126 M× 0.0250 = 0.00315 Moles
Moles of hydrogen fluoride after the addition of HCl
= 0.00315 + 5.0× 10^-5 = 0.0032 moles
Therefore, the concentration of Hydrogen chloride
= 0.0032 moles/ 0.030 L
= 0.107 M
