The density of solutions are assumed to be the same as water. If the density of all 3 solutions was actually 1.1 g/mL, how would the heat of the reaction be affected?
Draw a schematic of the flow. Clearly define and label the axes and any variables to be used. Indicate on the schematic the fluid on top and bottom of the slit.
If a mixture of 41.25 g of aluminum and 58.83 g of oxygen reacts, what mass of aluminum oxide can be formed?
How much heat is required to warm 227 g of ice from -44.9°C to 0.0°C, melt the ice, warm the water from 0.0°C to 100.0°C, boil the water, and heat the steam to 173.0°C?
An automobile gasoline tank holds 36 kg of gasoline. When the gasoline burns, 95 kg of oxygen is consumed, and carbon dioxide and water are produced.
Why does a piece of potato break down a 100% hydrogen peroxide solution faster than lets say a 75% hydrogen peroxide and 25% water
A 51.0 g sample of ethylene glycol, HOCH2CH2OH, is dissolved in 540.0 g of water. The vapor pressure of water at 32°C is 35.7 mm Hg. What is the vapor pressure of the water-ethylene glycol solution at 32°C? (ethylene glycol is nonvolatile.)
