Problem- A 50/50 blend of engine coolant and water (by volume) is usually used in an automobile's engine cooling system. If your car's cooling system holds 5.20 gallons, what is the boiling point of the solution? Make the following assumptions in your calculation; at normal filling conditions, the densities of engine coolant and water are 1.11 g/mL and 0.998 g/mL respectively. Assume that the engine coolant is pure ethylene glycol (HOCH2CH2OH), which is non-ionizing and non-volatile, and that the pressure remains constant at 1.00 atm. Also, you'll need to look up the boiling-point elevation constant for water.

What is the maximum amount of O2 in grams that can be obtained from 2.00 x 102 g of nitroglycerin?
It is often possible to change a hydrate into an anhydrous compound by heating it to drive off the water (dehydration).
CaC2(s) + 2H2O(l) = C2H2(g) + Ca(OH)2(aq) . If 34 g of CaC2 are consumed in this reaction, how much H2O is needed?
Explain the equation is provided below, but, when break up the NH4OH(aq) into its ions= NH3+ and H2O(l) I can't seem to get the equation balanced.
The Cr electrode acts as the anode, and the Ag electrode acts as the cathode. To maintain electric neutrality, you add a KNO3 salt bridge separating the two half-cells. Use this information to solve Parts B, C, and D. The half-cell is a chamber in..
