It is endothermic and the ∆H = +393.5 kJ.
B.) Helium have <span>two protons and two electrons
Hope this helps!</span>
∆H = m x s x ∆T, where m is the mass of the reactants, s is the specific heat of the product, and ∆T is the change in temperature from the reaction.
Answer:
The answer is its equal to the volume of its container.
