5.6 atm
In a container, the sum of partial pressures equals the total pressure. If the sun is 9.8 atm and the partial pressure of oxygen is 4.2 atm, the rest of the gases must account for the other 5.6 atm.
Reactivity.
All the others are examples of a physical property.
Answer:
atoms
Explanation:
![0.85 moles Fe*\frac{6.022*10^2^3}{1 mole Fe} =5.12*10^2^3](https://tex.z-dn.net/?f=0.85%20moles%20Fe%2A%5Cfrac%7B6.022%2A10%5E2%5E3%7D%7B1%20mole%20Fe%7D%20%20%3D5.12%2A10%5E2%5E3)
Use dimensional analysis to convert to moles by putting the moles of Fe (iron) on top and multiply by Avogadro's constant to cancel out moles and be left with atoms.
The balanced equation is 2H2 + O2 –> 2 H2O. It takes two hydrogen atoms for every oxygen atom to produce this reaction, so the mole ratio between hydrogen and oxygen is 2:1
Answer is 2:1
Answer: The quantity of heat produced by the reaction is +26710.656J
Explanation:
Quantity of Heat, Q = mass * specific heat capacity *temperature change
Q = mCpTc, where m= mass, Cp= specific heat capacity, Tc is temperature change
m= 210.0g, Cp=4.184J/(g · oC), Tc= 57.6 - 27.2 = 30.4 oC
Q = 210.0g *4.184J/(g · oC) * 30.4 oC
Q = +26710.656J
Therefore, the quantity of heat produced by the reaction is +26710.656J.
Note: <em>Even though heat is given out by the system and is normally written as a negative value to indicate that heat is lost, the answer is written as a positive decimal number according to instruction.</em>
