Based on observation of polar and non-polar molecules, polar molecules would attract each other more strongly.

<h3>What are polar and non-polar molecules?</h3>

Polar molecules are those molecules that can ionize or dissociate into their respective positive and negative ions when in an aqueous solution.

Nonpolar molecules, on the other hand, are not ionic i.e. not dissociating into ions when dissolved in water.

Polar molecules like water (H2O) contains an uneven distribution of cations (+) and anions (-), hence, would be more attracted to one another than nonpolar molecules that have an even distribution of ions.

Why couldn't you substitute 3m H2SO4 for concentrated HNO3 when oxidizing copper?
schepotkina [342]

This question seems to be an essay question from experiment. Different solution of oxidizing agent will have different strength.  Sulfuric acid or H2SO4 is weaker oxidizing agent when compared to nitric acid (HNO3). In this case, if you subtitute the H2SO4 you wouldn't be able to get the same result for the experiment.

The reform reaction between steam and gaseous methane (CH4) produces "synthesis gas," a mixture of carbon monoxide gas and dihyd
kenny6666 [7]

Answer:

The answer is "= 0.078 \ kg \ H_2".

Explanation:

calculating the moles in CH_4 =\frac{PV}{RT}

                                                =\frac{(0.58 \ atm) \times (923 \ L) }{ (0.0821 \frac{L \cdot atm}{K \cdot mol})(232^{\circ} C +273)}\\\\=\frac{(535.34 \ atm \cdot \ L) }{ (0.0821 \frac{L \cdot atm}{K \cdot mol})(505)K}\\\\=\frac{(535.34 \ atm \cdot \ L) }{ (41.4605 \frac{L \cdot atm}{mol})}\\\\= 12.9 \ mol

Eqution:

CH_4 +H_2O \to  3H_2+ CO \ (g)

Calculating the amount of H_2 produced:

= 12.9 \ mol CH_4 \times  \frac{3 \ mol \ H_2 }{1 \ mol \ CH_4}\times \frac{2.016 g H_2}{1 \ mol \ H_2}\\\\= 78 \ g \ H_2 \\\\= 0.078 \ kg \ H_2

So, the amount of dihydrogen produced = 0.078 \frac{kg}{s}

You believe you have cracked a secret code that uses elemental symbols to spell words. The code uses numbers to designate the el
Stells [14]

Explanation:

Atomic numbers for neutral atoms are the same as the number of electrons. The number of electrons are used in writing the subshell notation where we can see the highest princpal quantum number(n).

In order to solve this problem, a good knowledge of the periodic table and shell notation is required.  

For example;  

  Given a number 5;  

     We know the number is made of both the atomic number of the element and the highest quantum number.  

  It is easier for us to know the highest quantum number from the shell notation:  

        shell notation 1s²2s²2p¹

        highest principal quantum number is 2

  We are left with atomic number 5-2, which is 3

           The element is therefore Li.  

Part A.   5,     30,      58,      56,     99,     79,    19,     98,     9

             Li       Fe        I         Sb       U       Ta      S      Pa     N

Part B.   9,    99,    30,     95,     19,     47,     79

             N      U       Fe      Ra      S       Mo     Ta
