Answer:

B. C₃H₈ + 5O₂ → 3CO₂ + 4H₂O

Explanation:

  • A combustion reaction can be defined as a class of chemical reactions, that named as "burning", that occurs usually when a <em>hydrocarbon reacts with oxygen to produce carbon dioxide (CO₂) and water (H₂O).</em>
  • So, the correct answer is the choice B, 1.0 mole of propane "hydrocarbon" burned with 5.0 moles of oxygen to produce 3.0 moles of CO₂ and 4.0 moles of H₂O.

Explain why heat is often used in a laboratory experiment. a. To warm up the laboratory, b. To speed up a reaction
uysha [10]

Answer:

To speed up a reaction

Explanation:

Heat, as well as catalysts, increase the reaction rate of some chemical reactions since they cause the enzymes or reagents in charge of carrying out the transformation to products to act faster and increase their kinetic energy of reaction.

How might the molecules inside an ice pack be different from the liquid inside of an insulated cup?​
MatroZZZ [7]

Answer:

The molecules inside the ice pack are frozen therefore they are stuck in place. The molecules inside an insulated cup aren't frozen but still stuck inside of their container so that they can not fly out.

Give the ground-state electron configuration for silicon (SiSi) using noble-gas shorthand. Express your answer in condensed form
nydimaria [60]

Answer:

[Ne] 3s² 3p²

Explanation:

Silicon atoms have 14 electrons. The ground state electron configuration of ground state gaseous neutral silicon is 1s²2s²2p⁶3s²3p².

Using noble gas shorthand, the electronic configuration is reduced to;

[Ne] 3s² 3p². Ne s the nearest noble gas to silicon, Ne contains 8 electrons, this means there's still 4 more electrons to fill. The s orrbital can only hold 2, hence the reaing two is transferred to the p orbital.
