the first one sentence should be writter in this way: El veintiocho de octubre de mil setecientos cuarenta y seis un poderoso terremoto causó graves daños a la ciudad y destruyo el Callao.

the second one sentence should be written in this way: Este desastre llevó a una intensa devoción por una imagen de Cristo llamada El Señor de los Milagros.

Tried that...not right

It's apparently a different formula since the temperature is not the standard 298 K Work for the first: delta G is equal to -514.4 kJ lnK = 514.4/(0.008314)(550) lnK = 112.5 e^112.5 = 7.17*10^48 = k - which Mastering Chemistry says is wrong

I figured it out... You use the formula ln(k2/k1) = (delta H)/R * [(1/T1)-(1/T2)] 1) 5.24 * 10^44 2) 8.86 * 10^-13

Weight varies according to whether or not you are in Earth gravity. Mass is constant. This is a physical change, so I think that its form changed. Density is how much mass is spread over volume.

For B should the mixed number be 7/2?

You have to remember that there's no force being created on the x axis, the answer below must've been wrong because of that.

it would be 2.40*9.81 which would get you 23.554N.

oops i also forgot to do 23.554cos(36.3) which would be 18.983.
