A. loses electron, bc electrons are negatively charged, protons are positively charged, when electrons are lost, that means there are more protons more
Answer:
Fe₂O₃ + 3Zn → 2Fe + 3ZnO
Explanation:
Step 1: RxN
Fe₂O₃ + Zn → Fe + ZnO
Step 2: Balance RxN
We need 2 Fe's on both sides.
We also need 3 O's on both sides.
- If we multiply ZnO by 3, we will need 3 Zn's as well
Fe₂O₃ + 3Zn → 2Fe + 3ZnO
2,8,1
It's in group 1, so its outershell only has 1 electron, and the other shells are completely filled, so 2 then 8. :)
Answer:
True
Explanation:
The gaseous state is characterized in that the cohesion forces are usually null, in which the particles have their maximum mobility. The particles tend to occupy all the available volume, so their shape and volume are variable. The gaseous state is a dispersed state of matter, which means that the molecules are separated by distances much larger than the diameter of the gas molecules.
Answer:
D
Explanation:
A covalent bond is said to be formed when two electrons are shared between two bonding atoms as in the formation of the water molecule.
