The paper clips will magnetically connect to the nail. With the copper wire wrapped around then nail, it makes a magnetic field that, when powered will cause metal objects to come toward it, hence why it is called an "electromagnet".
Hope this helps!!!
Metal
On the periodic table its atomic number is 89
The Semi-metals aka the metalloids are atomic umbers 5,14,32,33,51,52,and 85
The Metals are everything that is located to the left of the metalloids excluding Hydrogen(H) and Helium (He)
Everything to the right of the metalloids are non-metals including Hydrogen (H) and Helium (He)
Answer:
The balanced equation would be
2Na(s) + 2H2O(l) ===> 2NaOH(aq) + H2(g)
where
s---solid
l--- liquid
aq--- aqueous
g---- gas
Are the states of each substance
Answer:
Applying this same method to the carbonate ion, we have 3 resonance structures with bond orders of 2, 1, 1 when considering the bond between carbon and a single oxygen.
Explanation:
CO32- has three resonating structures. The way to calculate the bond order for most conpounds having resonating structures is:(No.of bonds/No.of resonating structures) Since, CO32- has 4 bonds, Thus answer will be 4/3 or 1.3333..
