Answer:
Molarityof the solution is 0.1375 M.
Explanation:
We will first find the number of moles of diethyl ether (C4H10O) by finding its molar mass and measured mass.
Molar mass of diethyl ether (C4H10O) = 74.12 g.
Now, volume of diethyl ether (C4H10O) = 1.15 mL and its density = 0.7134 g/mL.
Therefore, measured mass of diethyl ether (C4H10O) = volume x density = 1.15 mL x 0.7134 g/mL = 0.82 g.
Now, number of moles of diethyl ether (C4H10O) = 
= 0.011 Moles.
Volume of the solution = volume of diethyl ether + volume of dichloromethane = 1.15 mL + 78.85 mL = 80 mL.
Now, molarity of the solution = Number of moles of diethyl ether / Volume of the solution( in mL) x 1000 = 
The balanced reaction that describes the reaction between sulfuric and sodium hydroxide to produce sodium sulfate and water is expressed <span>H2SO4 + 2NaOH → 2H2O + Na2SO4. When 65.5 grams of sodium hydroxide reacts with excess sulfur, we need first to convert the mass to moles and multiply by stoich ratio 2/2 or 1. Hence the moles is multiplied to the molar mass of water. The final answer is 29.475 grams water.</span>
One claim that supports one law of thermodynamics in photosynthesis is that energy is conserved, but the form of energy changes (Law 1).
<h3>What is photosynthesis?</h3>
Photosynthesis is a process done by plants and other organisms to obtain energy. This process implies a set of reactions that aim at converting light energy into chemical energy the organisms can use.
<h3>How is photosynthesis related to thermodynamics?</h3>
One way photosynthesis supports the laws of thermodynamics is through the first law that establishes energy is conserved, but the form of the energy can change.
This is because, in photosynthesis, the initial solar energy is transformed into chemical energy by storing the energy in carbon-hydrogen chemical bonds. This means the form of energy has changed but the energy is preserved.
Note: This question is incomplete because the graph is not given; due to this, I answered it based on general knowledge.
