Answer:
1,31÷2 =10,11
Explanation:
c10h22+31÷2o2=10co2+11h2o
Answer:
The purpose of the experiment is to see how water of different temperature and salinity affect the density.
Explanation:
Temperature and salinity directly affect the density of the water. Water of low temperature is more dense than water of high temperature, BUT, (fresh)water with no salt is less dense than (sea)water with more salt, so temperature and salinity change density of water.
<h2>Answer:</h2>
<em>8.67kJ/mol</em>
<h2>Explanations</h2>
The formula for calculating the amount of heat absorbed by the water is given as:

Determine the moles of KI

Since heat is lost, hence the enthalpy change of the solution will be negative that is:

Determine the enthalpy of solution in kJ•mol-1

Hence the enthalpy of solution in kJ•mol-1 for KI is 8.67kJ/mol
C) Steam has the most energy.
Steam has more energy than Ice and Water because the particles in ice are close together, the particles in water flow more loosely than in a solid like ice and in steam they are very active.
I hope that helps u understand :)
