Boyle's law gives the relationship between pressure of a gas and volume.
It states that at a constant temperature the pressure of gas is inversely proportional to volume of gas.
PV = k
where P - pressure, V - volume and k - constant
P1V1 = P2V2
where parameters for the first instance are given on the left side and parameters for the second instance are given on the right side of the equation.
substituting these values in the equation
6.21 atm x 3.17 L = 5.57 atm x V
V = 3.53 L
new volume is 3.53 L
Answer:
As a general rule, soluble ionic compounds, strong acids, and strong bases should be written as dissociated ions in the complete ionic equation. Insoluble salts and weak acids are written using the neutral molecular formula since they only dissociate to a very small extent in water.
Explanation:
I think the answer is tenfold
hope this helps :)
Explanation:
The results shows the reactivity of the halogens and how they displace one another from any solution of their compounds.
The oxidizing power of the halogens decreases from top to down on the group. This explains why the more powerful oxidizing halogens displaces the less powerful one from simple salts.
We see that chlorine is able to displace Bromine and iodine
Bromine is only able to displace Iodine
Iodine cannot displace bromine or chlorine
1. Endothermic reaction
2. Exothermic reaction
3. Exothermic reaction
<u>Explanation:</u>
1. Evaporation of alcohol from the skin, here the heat is absorbed by the alcohol so that it gets evaporated from the skin and it is an endothermic process. As the reaction says that, the energy is added to the system, so it is endothermic.
C₃H₈O + 5.2 kJ → C₃H₈O(g)
2. Burning of propane in a gas grill:
C₃H₈ + 5O₂ → 3CO₂ + 4H₂O + 1652 kJ.
Here energy is released or given out which is termed as exothermic reaction.
3. Oxidation of iron to form rust:
4 Fe + 3O₂ → 2 Fe₂O₃ + 2221 kJ.
Here also energy is released along with the products, so it is termed as exothermic reaction.
Whenever energy is absorbed, the reaction is endothermic in contrast if the energy is released then the reaction is exothermic.
