Answer:
The kind of bond formed depends on the identity of the bonding atoms and the shape of the molecule formed for covalent bonds.
Explanation:
There are various kinds of chemical bonds that could be present in a compound;
I) ionic bond
ii) covalent bond
iii) metallic bond
The kind of bond present in the compound depends on the elements involved in the bond. Metals and nonmetals mostly form ionic bonds win which electrons are transferred from metal to nonmetal.
Nonmetals commonly form covalent bonds with each other by sharing electrons in single, double and triple bonds. One may decide if the bond between two elements is ionic, covalent or polar covalent by looking at the electro negativity difference between the bonding atoms as well as the observed molecular geometry.
Finally, two metals are bonded by metallic bonds. This is the kind of bonds found in metallic crystals.
Answer:
<h3>The answer is 78 g</h3>
Explanation:
The mass of a substance when given the density and volume can be found by using the formula
<h3>mass = Density × volume</h3>
From the question
volume = 10 cc
density = 7.8 g/cc
So we have
mass = 7.8 × 10
We have the final answer as
<h3>78 g</h3>
Hope this helps you
Answer : The number of silver atoms produced will be
Explanation : Given,
Number of atoms of copper =
The given balanced chemical reaction,
From the balanced chemical reaction we conclude that,
As, number of copper atoms react to give number of silver atoms.
So, number of copper atoms react to give number of silver atoms.
Therefore, the number of silver atoms produced will be
