Chemistry
2 answers:
Zielflug [23.3K]3 years ago
8 0

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.

ira [324]

Answer:

333.33 KPa

Explanation:

P1V1=P2V2

p2=P1v1/v2

p2= (2.50 L* 100 kPa)/0.75 L

P2=333.33 kPa

Explain the Valence Bond Theory in a paragraph not less than five sentences
Morgarella [4.7K]
A valence bond is something used to explain chemical bonding. And as well a molecular orbital. So Two atoms that have unpaired electrons in their orbitals that overlap rises to give a chemical bond. So basically. The two atoms give each other's unpaired electron to form a filled orbital to make a hybrid orbital and for it to bond together.

Suppose 45.0 g of water at 85 °C is added to 105.0 g of ice at 0 °C. The molar heat of fusion of water is 6.01 kJ/mol, and the s
Elis [28]

Answer:

A. Final Temp = 36.428C and

47.9g ice will melt

Explanation:

Given the following data:

Mass of water (M1) = 45.0g = 0.045kg

Temperature (T1) = 85C = 358k

Mass of ice (M2) = 105g = 0.105kg

Temperature (T2) = 0c = 273k

Specific heat of water (C) = 4.18j/gC = 0.00418kj/kgc

Molar heat of fusion of water = 6.01kj/mol

Therefore, heat required (q) = MCT

M1C(T1-T2) = M2C∆T

By putting the data we have

0.045×0.00418×(358-273) = 0.105×0.00418×∆T

∆t = 0.045×0.00418×85/0.105×0.00418

∆t = 36.428C

Gram of ice that would melt would be 47.9g

How many grams of SO2 can be produced if<br> 2.5 moles of O2 are used?<br> S2 + 2O2 → 2SO2
loris [4]

Answer: mass of SO2 is 160 g

Explanation: according to equation number of moles of SO2

Is same as amount of Oxygen, also 2.5 moles.

Molar mass of SO2 is 32.07 +2·16 = 64.07 g/mol

Mass is m= nM = 2.5 mol· 64.07 g/mol= 160.175 g
