ankoles [38]
It will sink below the surface. Since dish soap is a surfactant, it will alter the water's surface tension. Lowering the surface tension, the water will no longer be able to support the mass of the twig.

2C3H7OH + 9O2 -> 6CO2 + 8H2O
MAVERICK [17]

Answer:

Up to 18\; \rm mol \rm CO_2.

Explanation:

The equation for this reaction: 2\; \rm C_3 H_7 OH + 9\; O_2 \to 6\; CO_2 + 8\; H_2O is indeed balanced.

Notice that the coefficient of \rm C_3 H_7 OH is 2 while that of \rm CO_2 is 6.

Therefore, each unit of this reaction would consume 2 units of \rm C_3H_7OH while producing 6 units of \rm CO_2. In other words, this reaction would produce three times as much \rm CO_2\! as it consumes \rm C_3H_7OH\!.

If all that 6\; \rm mol of \rm C_3H_7OH molecules are actually consumed through this reaction, three times as many \rm CO_2 molecules would be produced. That corresponds to 3 \times 6\; \rm mol = 18\; \rm mol of \rm CO_2\! molecules.

The combustion of a sample of butane, C4H10 (lighter fluid), produced 2.46 grams of water.
hodyreva [135]
The first step with any of these problems is putting the mass in grams in terms of moles. How many moles of water are represented by 2.46 g of water? The relationship is the molar mass of water, which is about 18 g/mol. So dimensional analysis shows that 2.46 g water = 2.46 g/18 g = 0.0556 moles of water. That's part a.
