PLS HELP!! <br> Balance this equation: __H2+ 2 O2---&gt; 2 H2O
alekssr [168]

Answer:

 2H₂   +   O₂  →   2H₂O

Explanation:

The expression of the equation is given as:

              _H₂   +   2O₂  →   2H₂O

Now for expression above,

                           Reactants                                          Products

H                              2                                                            4

O                              4                                                           2

to balance the equation, we use 2 moles of hydrogen gas and 1 mole of oxygen gas;

           2H₂   +   O₂  →   2H₂O

The melting point of phenol is 40.5∘C and that of toluene is −95∘C. What is the best explanation for this difference? Select the
romanna [79]

Answer:

None of the above

Explanation:

The (−OH) group on phenol can form hydrogen bonds, and the −CH3 group on toluene cannot.

Phenol has only one hydrogen on the −OH group available to form hydrogen bonds, so the hydrogen bond is stronger. In toluene, the hydrogen bond is spread over all three hydrogens on the methyl group, so the interaction is weaker overall.

Phenol has a higher molecular mass than toluene.

What can be deduced about two gases that have<br> the same molecular mass?
snow_tiger [21]

Answer: Spanish = La ley de Avogadro establece que "los volúmenes iguales de todos los gases, a la misma temperatura y presión, tienen el mismo número de moléculas". Para una masa dada de un gas ideal, el volumen y la cantidad (lunares) del gas son directamente proporcionales si la temperatura y la presión son constantes.

English = Avogadro's law states that "equal volumes of all gases, at the same temperature and pressure, have the same number of molecules." For a given mass of an ideal gas, the volume and amount (moles) of the gas are directly proportional if the temperature and pressure are constant.
