C - Analyze data and draw conclusions. After an experiment or in this case; an investigation, you would analyze your data that you collected from the investigation/experiment, and draw conclusions based on your data.
Answer:
A scientist measures the standard enthalpy change for the following reaction to be -139.5 kj :
h2(g) + c2h4(g)c2h6(g)
based on this value and the standard enthalpies of formation for the other substances, the standard enthalpy of formation of c2h4(g) is _____ kj/mol
Explanation:
Hydrogen ΔHof (kJ/mol) ΔGof (kJ/mol) So (J/mol K)
H2 (g)
0
0
130.7
Carbon ΔHof (kJ/mol) ΔGof (kJ/mol) So (J/mol K)
C2H6 (g)
-84.7
-32.8
229.6
Answer:How do you calculate the pH of a sulfuric acid solution?
So, the pH of the sulfuric acid solution can then be calculated: pH = -log10[H+(aq)] pH = -log10[c + x]
...
Example: Calculating pH of Sulfuric Acid using R.I.C.E. Table and Quadratic Equation.
x = -b ± √(b2 -4 × a × constant) 2a
(i) x = (-0.512 + 0.535)/2 = 0.012
Explanation:
Answer is: C. a long chain of carbon atoms with hydrogen atoms attached to them.
Starch is example of polymer.
Main component of bread is flour and main component of flour is starch.
Starch is a polymeric carbohydrate consisting of a large number of glucose units bonded by glycosidic bond. Starch is a white, tasteless and odorless powder that is insoluble in cold water or alcohol.
Another example, polystyrene is a synthetic aromatic hydrocarbon polymer made from the monomer styrene.
