Answer:
1 ans =The atoms that the electrons leave behind become positive ions, and the interaction between such ions and valence electrons gives rise to the cohesive or binding force that holds the metallic crystal together.
Answer:
m O2 = 116,16 g
Explanation:
Ca(ClO3)2 ------------> CaCl2 + 3O2
n Ca(ClO3)2 = 250/207 = 1,21 mol
n O2 = 3n Ca(ClO3)2 = 1,21 * 3 = 3,63 mol
m O2 = 3,63 * 32 = 116,16 g
Answer:
i guess fuels are chemicals
Answer:4.42 g= 1 mol/55.845 =.079 moles of Fe
Explanation:Given 4.42 grams of Fe. The atomic weight of Fe(iron) found on the periodic table is 55.845. Divide grams by the atomic weight to convert to moles.
