(2) ionic and is formed by the transfer of two valence electrons
(3) covalent and is formed by the sharing of two valence electrons
(4) covalent and is formed by the transfer of two valence electrons
The bond between Br atoms in a Br2 molecule is covalent and is formed by the sharing of two valence electrons.
The bond between Br atoms in a Br2 molecule is covalent and is formed by the sharing of two valence electrons.
In a covalent bond, atoms share electrons to complete their outer electron shell. In the case of a Br2 molecule, each Br atom has 7 valence electrons and needs 1 more electron to achieve a stable octet arrangement, so they share one pair of electrons to achieve this.
The bond between Br atoms in a Br2 molecule is covalent and is formed by the sharing of two valence electrons.

report the answer to the
appropriate number of
significant figures.
1204.2 +4.79613 = [ ? ]
This problem is providing a mathematical expression which the result should be expressed with the correct significant figures. At the end, the result is 1209.0 because of the following:
In science, the use of significant figures is crucial as long numbers are not necessarily required when reporting a numerical value, for that reason the importance of reporting measurements with the correct number of significant figures.
In the case of additions, we perform the normal operation as the first step:
1204.2 +4.79613 = 1208.99613
Next, we round the result to the leastnumber of decimal places, in this case one because 1204.2 has just one decimal place, unlike the 4.79613 which has five, so that we round the 8 up to 9 and leave a 0 as the onlydecimalplace:
1209.0

The expression for representation of concentration of a solution has been 3.5 M. Thus, option 2 is correct.
Concentration has been defined as the amount of substance present in a volume of solution. The concentration has been given by varying units. The concentration has been given by mass per unit volume.
It can be represented by moles/L or g/L. The expression that has been similar to moles/L has been molarity.
Thus, the expression for representation of concentration of a solution has been 3.5 M. Thus, option 2 is correct.
