Butane, C4H10 C 4 H 10 , is a component of natural gas that is used as fuel for cigarette lighters. The balanced equation of the complete combustion of butane is2C4H10(g)+13O2(g)→8CO2(g)+10H2O(l ) 2 C 4 H 10 ( g ) + 13 O 2 ( g ) → 8 C O 2 ( g ) + 10 H 2 O ( l ) At 1.00 atm a t m and 23 ∘C ∘ C , what is the volume of carbon dioxide formed by the combustion of 4.00

Which of the following statements about hybrid orbitals is or are true? choose all that apply. choose all that apply. under sp2 hybridization, the large lobes point to the vertices of an equilateral triangle. after an atom undergoes sp hybridization there is one unhybridized p orbital on the atom. the angle between the large lobes of sp3 hybrids is 109.5∘

Acalorimeter is to be calibrated: 51.203 g of water at 55.2 degree c is added to a calorimeter containing 49.783 g of water at 23.5c. after stirring and waiting for the system to equilibrate, the final temperature reached is 37.6 degree c. specific heat capacity of water (s = 4.18 j/g∙degree c). calculate the calorimeter constant. (smδt)warm water = -[(smδt)cold water + (calorimeterδtcold water)]

Which material burns faster? metal aluminum
