Answer:
Nitrogen has 7 protons, 7 neutrons, and 7 electrons.
So, I'm not entirely sure about the choices you provided :)
Answer:
Carbon-12 is composed of 6 protons, 6 neutrons, and 6 electrons.
Explanation:
Ionic bond (electrovalent bond) is the exchange of ions between atoms of different element while covalent bond is the sharing electron between atoms
The balanced reaction is:
<span>Cu + 2AgNO3 = 2Ag + Cu(NO3)2
We are givent the amount of silver to be produced. This will be the starting point. Calculations are as follows:
</span><span> 3.50 mol Ag ( 1 mol Cu / 2 mol Ag ) = 1.75 mol Cu
</span>
Therefore, we need 1.75 mol of copper in order to produce 3.50 mol of silver.
Answer:
- <u><em>polar covalent bond.</em></u>
Explanation:
Polar covalent bonds are formed when the electrons are not shared equally.
The unequal sharing of electrons happens when the electronegativities of the atoms that form the bonds are different.
The electronegativity of<em> hydrogen </em>atoms is found to be 2.20 and that of <em>oxygen</em> is 3.44.
So, the electronegativity difference found in a H - O bond is 3.44 - 2.20 = 1.24.
That means that oxygen atoms pull the electrons more strongly than hydrogen atoms, which results in that the electrons spend more time closer to the hydrogen atoms than to the oxygen atoms.
