El metal Mg reacciona con el Hcl para producir gas Hidrógeno Mg +2HCl---MgCl2 + H2. ¿Qué volumen en Litros de H2 en condiciones STP se liberan cuando reaccionan 8.25g de Mg? * 8.60L 6.60L 7.60L 16.60L

7.60 L of hydrogen gas will be liberated.

Explanation:

The number of moles is defined as the ratio of the mass of a substance to its molar mass.

The equation used is:

   ......(1)

Given mass of Mg = 8.25 g

Molar mass of Mg = 24.305 g/mol

Plugging values in equation 1:

The given chemical equation follows:

By the stoichiometry of reaction:

If 1 mole of magnesium produces 1 mole of hydrogen gas

So, 0.340 moles of magnesium will be produce = of hydrogen gas

At STP conditions:

1 mole of a gas occupies 22.4 L of volume

So, 0.340 moles of hydrogen gas will occupy = of hydrogen gas

Hence, 7.60 L of hydrogen gas will be liberated.

answer: option (b) is the correct answer.

explanation:

a covalent bond is formed by sharing of electrons. whereas polarity arises due to difference in electronegativity of two atoms.

therefore, more is the electronegativity of an atom which combines with the titanium, more readily it will induce a partial positive and negative charge.

thus, out of the given options fluorine is most electronegative and has an incomplete octet. therefore, it will readily combine with titanium to share the electrons and complete its octet.  

answer

fusion: the energy source of stars. the energy released from the collapse of the gas into a protostar causes the center of the protostar to become extremely hot. when the core is hot enough, nuclear fusion commences. fusion is the process where two hydrogen atoms combine to form a helium atom, releasing energy.
