The entropy change ΔS for the combustion of methane to carbon dioxide and liquid water is -242.6 J/mol.K
<h3>What is the Entropy in a Chemical system?</h3>
In a chemical system, Entropy (ΔS) is a quantitative measure of the variety of possible ways to disperse energy inside a chemical system.
- In an isothermal process, entropy is determined as the quantity of heat transmitted to a system.
The chemical reaction for the combustion of methane can be expressed as:
The standard entropy of the combustion is expressed as:
Replacing the standard entropies of the compounds into the above equation, we have:

Answer:
119.24
Explanation:
Step 1: We make the assumption that 369 is 100% since it is our output value.
Step 2: We next represent the value we seek with x.
Step 3: From step 1, it follows that 100%=36.
Step 4: In the same vein, x% = 440.
Step 5: This gives us a pair of simple equations:100%=369(1) 440(2) = x%
Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS(left hand side) of both equations have the same unit (%); we have 100%/x% = 369/440
Step 7: Taking the inverse (or reciprocal) of both sides yields x%/100% = 440/369
Therefore, 440 is 119.24% of 369.
Answer:
b) Find the t-value such that the area in the right tail is 0.01 with 11 degrees of freedom
Explanation:
The FitnessGram PACER Test is a multistage aerobic capacity test that progressively gets more difficult as it continues. The test is used to measure a student's aerobic capacity as part of the FitnessGram assessment. Students run back and forth as many times as they can, each lap signaled by a beep sound.
