An Ionic Bond
Explanation:
Salt compounds are formed by the "donating" of electrons.
Answer:
A. Jordan is on a moving train. He throws the ball toward the front of the train
Explanation:
Use the formula for volume. V = lwh. Plug in the numbers for length, width, and height. Now we have V = 4.0 x 2.0 x 1.0, which is 8.0. So the volume of the block is 8.0 cm.

Answer: 
for the reaction is -90kJ
Explanation:
The balanced chemical reaction is,
The expression for Gibbs free energy change is,
![\Delta G=[n\times G_{products}]-[n\times G_{reactants}]](https://tex.z-dn.net/?f=%5CDelta%20G%3D%5Bn%5Ctimes%20G_%7Bproducts%7D%5D-%5Bn%5Ctimes%20G_%7Breactants%7D%5D)
Putting the values we get :
![\Delta G=[3\times G_f{S,rhombic}+2\times G_f{H_2O}]-[2\times G_f{H_2S}+1\times G_f{SO_2}]](https://tex.z-dn.net/?f=%5CDelta%20G%3D%5B3%5Ctimes%20G_f%7BS%2Crhombic%7D%2B2%5Ctimes%20G_f%7BH_2O%7D%5D-%5B2%5Ctimes%20G_f%7BH_2S%7D%2B1%5Ctimes%20G_f%7BSO_2%7D%5D)
![\Delta G=[(3\times 0kJ/mol)+(2\times -229kJ/mol)]-[(2\times -34kJ/mol) +(1\times -300kJ/mol)]](https://tex.z-dn.net/?f=%5CDelta%20G%3D%5B%283%5Ctimes%200kJ%2Fmol%29%2B%282%5Ctimes%20-229kJ%2Fmol%29%5D-%5B%282%5Ctimes%20-34kJ%2Fmol%29%20%2B%281%5Ctimes%20-300kJ%2Fmol%29%5D)
Thus for the reaction is -90kJ
