They both have 1 electron in their valence shell.....
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.
250gTi x (1mol/47.87 [molar mass]) =5.22247 moles
Answer:
3 moles of CaO
Explanation:
The chemical balanced equation is;
2Ca + O₂ → 2CaO
The ratio of calcium(Ca) to Calcium Oxide(Cao) in this equation is 2:2.
Now, when 3 moles of calcium react with oxygen, Cao produced will be;
3 moles of O₂ × 2 moles of CaO/2 moles of Cao = 3 moles of CaO
The answer is A! Heat energy is thermal energy. To remember all Energy use M.E.L.T.S!
M- Mechanical energy
E- Electrical energy
L- Light energy
T- Thermal energy
S- Sound energy
