The formula for energy or enthalpy is:
E = m Cp (T2 – T1)
where E is energy = 63 J, m is mass = 8 g, Cp is the
specific heat, T is temperature
63 J = 8 g * Cp * (340 K – 314 K)
<span>Cp = 0.3 J / g K</span>
The number of valence electrons of an element can be determined by the periodic table group (vertical column) in which the element is categorized
Answer: Helium is an type of air that can be used to inflate balloons, balls, and other things that require air. The carbon dioxide we breath out is similar to this helium.
