The bond between Br atoms in a Br2 molecule is(1) ionic and is formed by the sharing of two valence electrons
(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

Answers

The bond between Br atoms in an Br2 molecule is concealment and is formed by sharing of two valence electrons.

Final answer:

The bond between Br atoms in a Br2 molecule is covalent and is formed by the sharing of two valence electrons.

Explanation:

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.

Maple syrup, which comes from the sap of maple trees, contains water and natural sugars. It's a clear, brown liquid and the sugars can’t be separated by filtration. Under which category will you classify it?suspension
colloid
solution
compound
element

Answers

Here, the solution can't be separated by filtration means, the solute is dissolved at greater extent with solvent. The category would be: Colloid

In short, Your Answer would be: "Colloid"

Third time im asking... really need help..Assuming all of the atoms attached to the central atom were identical, which of the following geometries would produce a nonpolar molecule? (Only 3 choices are correct.)

-linear
-trigonal planar
-tetrahedral
-trigonal bipyramidal
-octahedral
-bent (angular)

Answers

I'm not an expert on this, but I have done some work. Non-symmetrical shapes are polar, so octahedral, tetrahedral and linear are non-polar since they are symmetrical

1204.2 +4.79613 = [ ? ]

Answers

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:

Significant figures:

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

Which expression could represent theconcentration of a solution?
(1) 3.5 g
(2) 3.5 M
(3) 3.5 mL
(4) 3.5 mol

Answers

There are a couple of ways in which you can express the concentration of a solution, and here they are: gram per liter (g/L), molarity (M), parts per million (ppm.), and percents (%).
As you can see, only M appears in your answers, which means that the correct option should be (2) 3.5 M.

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.
