When 37.5 ml of 0.625 m h2so4 is added to 37.5 ml of 1.25 m koh in a coffee-cup calorimeter at 23.50°c, the temperature rises to 30.17°c. calculate h of this reaction per mole of h2so4 and koh reacted. (assume that the total volume is the sum of the individual volumes and that the density and specific heat capacity of the solution are the same as for pure water: d = 1.00 g/ml and c = 4.184 j/g×k.) h per mole of h2so4 reacted:

answer: well the scientific fact is the a cell wall isn’t in all life

explanation:

i don,t know so just answer mine

percent abundance for cu-63 can be shown as:

63 x + 65 (1-x) = 62.9296

65 - 62.9296 = 2 x

x = 1.035

thus, percent abundance for cu-63 is 1.035

percent abundance for cu-65 can be shown as:

63 x + 65 (1-x) = 64.9278

65 - 64.9278 = 2 x

x = 0.0361

thus, percent abundance for cu-63 is 0.0361

the mass spectrum of cu-63 showing the intense peak as, this isotope is found in nature more abundantly around 92.38 % in comparison to cu-65 which is found 62.58 % naturally
