Identify the type of single replacement reaction in; 2Li(s) + 2 H2O(l) – 2LIOH(aq) + H2 (9)
water or matel or nonmatel . hydrogen reaction

"standard molar enthalpy:

h2o ( liquid water ) : - 285.8 kj/mole

h2o ( water vapor ) : - 241.8 kj / mole.

δhrxn = - 241. 8 - ( - 285.8 )= -241.8 + 285.8 = 44.0

answer: 44.0 kj"

no, the red giant is the hottest with 2.00.000.000 degrees celsius. while the white dwarf only 25,000 degrees celsius.

it forms an anion that has a larger radius. anions have a negative charge and are larger than the original atom.
