In a large building, oil is used in a steam boiler heating system. The combustion of 1.0 lb of oil provides 2.4 x 107 J How many kilograms of oil are needed to heat 120 kg of water from 28 C to 100 °C? (Assume that 1 lb = 454 g the specific heat of liquid water is 4.184 J/g °C.)

Express your answer to two significant figures and include the appropriate units. ​

the ratio of the conjugate base to the acid required to attain the desired ph.

the correct answer is b. a strong acid completely dissociates to its ions when dissolved in water. completely dissociates to and ions. a is incorrect because does not fully ionize to and ions and some remain as the compound . c and d are incorrect because, and do not fall into the category of bronsted lowry acids. a bronsted lowry acid is a proton donor and since both molecules do not have a proton to donate they are not bronsted lowry acids. likewise,   if we use the lewis acid definition, they cannot be acids. a lewis acid is an electron pair acceptor. both and have a complete octet so can not accept any electrons which disqualifies them as acids.

warm front forms when a moist, warm air mass slides up and over a cold air mass. as the warm air mass rises, it condenses into a broad area of clouds. a warm front brings gentle rain or light snow, followed by warmer, milder weather.
