Longitudinal waves. In a longitudinal wave the particles in the medium move parallel to the direction waves go. A good example can be the p-waves in an earthquake.
Answer:
Molecular Weight
Explanation:
Chromium(III) Carbonate Cr2(CO3)3 Molecular Weight -- EndMemo.
Answer:
176 g of CO₂.
Explanation:
We'll begin by writing the balanced equation for the reaction. This is illustrated below:
2C₂H₂ + 5O₂ —> 4CO₂ + 2H₂O
Next, we shall determine the mass of C₂H₂ that reacted and the mass of CO₂ produced from the balanced equation.
This is illustrated below:
Molar mass of C₂H₂ = (2×12) + (2×1)
= 24 + 2 = 26 g/mol
Mass of C₂H₂ from the balanced equation = 2 × 26 = 52 g
Molar mass of CO₂ = 12 + (2×16)
= 12 + 32 = 44 g/mol
Mass of CO₂ from the balanced equation = 4 × 44 = 176 g
From the calculations made above,
52 g of C₂H₂ reacted to produce 176 g of CO₂.
