Answer:
The answer to your question is molality = 0.61
Explanation:
Freezing point is the temperature at which a liquid turns into a solid if a solute is added to a solution, the freezing point changes.
Data
Kf = 1.86 °C/m
molality = ?
ΔTc = 1.13°C
Formula
ΔTc = kcm
Solve for m
m = ΔTc/kc
Substitution
m = 1.13 / 1.86
Simplification and result
m = 0.61
Answer:
2C₄H₁₀ + 13O₂ ⟶ 10H₂O + 8CO₂
Explanation:
2C₄H₁₀ + 13O₂ ⟶ 10H₂O + 8CO₂ . . . . . balanced combustion reaction
C₄H₁₀ + 5O₂ ⟶ 5H₂O + 4CO₂ . . . . not balanced
The two reactions involving Ca are not combustion reactions.
Answer: 270 g H2O
Explanation: solution attached
Use the relationship of 1 mole H2O is equal to its molar mass 18g H2O
15.0 moles H2O x 18g H2O / 1 mole H2O
= 270 g H2O
Answer: Carbon
Explanation: Organic compounds are those made by carbon atoms that link to other carbon or elements such as nitrogen, hydrogen or oxygen with covalent bonds.
The presence of these compounds were associated with living things, because most of them are produced by plants or animals. However nowdays substances like polymers and other synthetically made molecules can also be considered as organic since they are made of carbon.
