2) A student determined the melting point of a substance to be 55.2DC. If the accepted value is 50.1C, what is the percent error in the student's determination?
A) 12.0 B) 5.10 C) 10.2 D) 9.24

C) 10.2

Explanation:

Formula: Actual-Expected/Expected

The actual was 55.2 while the expected was 50.1

55.2-50.1/50.1=0.101796407 * 100= 10.2%

because u need two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei to form isotopes.

so since they all have the same shape? i mean maybe because m& m and reeses are both chocolates
