Answer:
whah the other dude said :) also stay safe
Explanation:
Because each element has an exactly defined line emission spectrum, scientists are able to identify them by the color of flame they produce.
B
Electrons are found in shells or orbitals that surround the nucleus of an atom
Hthe heat required to change the temperfature of 100 grams of water from 25 to 55 c is calculated as below
Q(heat) = M(mass) x C(specific heat capacity) x delta T(change in temperature)
M= 100 grams
C= 4.18 j/g/c
delta T= 55-25 =30c
Q=100 g x4.814 j/g/c x 30c = 12552 joules
