1.rosita went to baguio in talker 5 hours to travel a distance of a km what was the speed 2.how long was your trip when it covered a distance of 100 km at a speed of 50 km/h
3.tarlac is 180 km from manila how many meters are you going to travel if you want to visit your relatives in tarlac
4.gilbert runs at a speed of 9 km/h he runs for 6 hours how far does he travel
5.the rabbit runs for the distance of 12 meters in 6 seconds what is its speed ​

answer: enthalpy

explanation:

for a exothermic reaction, the energy is released i.e. the energy of the products is lower than the energy of the reactants.

= enthaply

= energy of products

= energy of reactants

as , thus comes out to be negative. negative value of enthalpy shows that the reaction is exothermic.

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
