What mass of lp gas is necessary to heat 1.3 l of water from room temperature (25.0 ∘ c ) to boiling (100.0 ∘ c )? assume that, during heating, 16% of the heat emitted by the lp gas combustion goes to heat the water. the rest is lost as heat to the surroundings. express your answer using two significant figures. lp gas burns according to the following exothermic reaction: c3h8(g)+5o2(g)→3co2(g)+4h2o(g)δh∘rx n=−2044kj

How is the shape of the poem “peer” connected to its meaning?

Ok, so i have 2 questions. try to answer them both: (the topic is fire) 1) how can you represent the chemical reaction of fire? 2) what kind of bond is formed in this chemical reaction

Determine the number of moles of air present in 1.35 l at 750 torr and 17.0°c. which equation should you use? n=pv/rt what is the number of moles present? ⇒ 0.056 mol a sample of n2 gas occupying 800.0 ml at 20.0°c is chilled on ice to 0.00°c. if the pressure also drops from 1.50 atm to 1.20 atm, what is the final volume of the gas? which equation should you use? v2= p1v1t2/p2t1 what is the final volume of the gas? ⇒ 932 ml these are the answers
