Soap is a polar covalent bond because its electrons are not shared equally between the atoms.

Soap is polar because it is not symmetrical in molecularly, this is because it must react with whats on your hand to fully clean it , dish soap is nonpolar/polar in order to combat grease which is also nonpolar, so nonpolar cleans nonpolar and polar cleans polar

Bodies of our solar system in proper Oder of formation

AnnyKZ [126]

The various planets are thought to have formed from the solar nebula, the disc-shaped cloud of gas and dust left over from the Sun's formation. The currently accepted method by which the planets formed is accretion, in which the planets began as dust grains in orbit around the central protostar.

LenKa [72]

Answer: 23 g

the mol of Fe is 11,5/56 = 23/112 (mol)

the mol of CO is $\frac{2,63.10^{24} }{6.10^{23} }= \frac{263}{60}$ (mol)

we have:

Fe2O3 + 3CO => 2Fe + 3CO2

23/112 69/112 23/56

=> the mol of Fe is 23/56 mol

=> the mass of Fe is 23/56.56 = 23 (g)

A multistep reaction can only occur as fast as its slowest step. Therefore, it is the rate law of the slow step that determines

kodGreya [7K]

Answer : The rate law for the overall reaction is, $Rate=k[A][B]$

Explanation :

Rate law : It is defined as the expression which expresses the rate of the reaction in terms of molar concentration of the reactants with each term raised to the power their stoichiometric coefficient of that reactant in the balanced chemical equation.

As we are given the mechanism for the reaction :

Step 1 : $A+B\rightarrow AB$ (slow)

Step 2 : $A+AB\rightarrow A_2B$ (fast)

Overall reaction : $2A+B\rightarrow A_2B$

The rate law expression for overall reaction should be in terms of A and B.

As we know that the slow step is the rate determining step. So,

The slow step reaction is,

$A+B\rightarrow AB$

The expression of rate law for this reaction will be,

$Rate=k[A][B]$

Hence, the rate law for the overall reaction is $Rate=k[A][B]$

Identify the correct statements associated with titration.

Montano1993 [528]

Answer:

Explanation:

because titration by definition, is used to determine the concentration of one reactant in an aqueous solution, it requires a burette to accurately measure the volume of a solution and endpoints in acid-base titration can be determined by a colour indicator or a pH meter

Star_____ has the greatest absolute brightness

Nitella [24]

Answer:

Star A would have the greater absolute brightness. This is because absolute brightness finds out the actual brightness of a star at a standard distance from Earth. If Star A is twice as far from Earth as Star B but they still both appear to have the same amount of brightness.
