Answer:they have the same number of electrons in the valence shell
Explanation:
Well you should study how different chemicals work, and make flashcards to carry around or make notes during class to study for later
Heat required in a system can be calculated by multiplying the given mass to the
specific heat capacity of the substance and the temperature difference. It is
expressed as follows:<span>
Heat = mC (T2-T1)
Heat = 10.0 g (4.18 J/g-C ) ( 6.0 C )
<span>Heat = 250.8 J</span></span>
Because some machine might not work and would give you the wrong answer
