Answer: nuclear
Explanation: Two nuclei are combining to form one
Answer:
2Fe + 3H2SO4 ---> Fe2(SO4)3 + 3H2
Explanation:
count the number of atoms of each of the elements on both sides of the equation. on the left, you have 1 Fe, 2H, 1 S, and 4 O. on the right you have 2 Fe, 3 S, 12 O, and 2 H. compare both of these. you can see that the number of atoms on both sides doesn't match up. add coefficients to the compounds and elements to balance them. it may take a while to get it right. make sure when you are re counting with the coefficient, you don't forget to distribute it to all atoms (for example, if you have 3H2SO4, you have 3 H2's, 3 S's, and 3 04's)
Answer: Think of each polar bond in a molecule as a little arrow pointing from positive to negative. So, the geometry of the molecule determines the direction that the bond dipole vectors point. The polarity of the molecule results from adding up all these individual bond dipoles.
