Answer:
.
Start color: yellowish-green.
End color: dark purple.
Assumption: no other ion in the solution is colored.
Explanation:
In this reaction, chlorine gas 
oxidizes iodine ions 
to elemental iodide 
. At the same time, the chlorine atoms are converted to chloride ions 
.
Fluorine, chlorine, bromine, and iodine are all halogens. They are all found in the 17th column of the periodic table from the left. One similarity is that their anions are not colored. However, their elemental forms are typically colored. Besides, moving down the halogen column, the color becomes darker for each element.
Among the reactants of this reaction, is colorless. If there's no other colored ion, only the yellowish-green hue of would be visible. Hence the initial color of the reaction would be the yellowish-green color of .
Similarly, among the products of this reaction, is colorless. If there's no other colored ion, only the dark purple hue of would be visible. Hence the initial color of the reaction would be the dark purple color of .
Molality is obtained by dividing the number of moles of solute by the mass in kilogram of the solvent. None of the dimensions is dependent in temperature. On the other hand, molarity is obtained by dividing the number of moles of solute by the volume in liters of the solution. Volume is temperature dependent.
They speed up reactions by lowering activation energy. Many enzymes change shape when substrates bind.
Answer: The pressure after the tire is heated to 17.3°C is 167 kPa
Explanation:
To calculate the final temperature of the system, we use the equation given by Gay-Lussac Law. This law states that pressure of the gas is directly proportional to the temperature of the gas at constant pressure.
Mathematically,
where,
are the initial pressure and temperature of the gas.
are the final pressure and temperature of the gas.
We are given:
Putting values in above equation, we get:
Hence, the pressure after the tire is heated to 17.3°C is 167 kPa
When it’s warmer so when temperature encreases
