Explanation:

Plastic takes time to degrade which means it has great longevity. Plastic does not break as easily as glass or other materials. It lasts long and offers great service. Plastic storage containers offer greater flexibility than any other packaging materials.

Answer:

781×10¯² g of MgCl₂.

Explanation:

The balanced equation for the reaction is given below:

Mg + 2HCl —> MgCl₂ + H₂

Next, we shall determine the mass of HCl that reacted and the mass of MgCl₂ produced from the balanced equation. This is illustrated below:

Molar mass of HCl = 1 + 35.5

= 36.5 g/mol

Mass of HCl from the balanced equation = 2 × 36.5 = 73 g

Molar mass of MgCl₂ = 24 + (35.5×2)

= 24 + 71

= 95 g/mol

Mass of MgCl₂ from the balanced equation = 1 × 95 = 95 g

SUMMARY:

From the balanced equation above,

73 g of HCl reacted to produce 95 g of MgCl₂.

Finally, we shall determine the mass of MgCl₂ produced by the reaction of 6 g of HCl. This can be obtained as follow:

From the balanced equation above,

73 g of HCl reacted to produce 95 g of MgCl₂.

Therefore, 6 g of HCl will react to produce = (6 × 95)/73 = 781×10¯² g of MgCl₂.

Thus, 781×10¯² g of MgCl₂ were obtained from the reaction.

Lead has an atomic number of 82. Which statement describes all neutral atoms and ions of lead?
IRINA_888 [86]

The neutral atom of lead must have 82 protons while ions can have b or less than 82.

The atomic number of an element is the number of protons in the nucleus of the element.

Also, for neutral atoms, the number of protons equals the number of electrons.

In ionic form, the number of protons/electrons of an atom may vary and be different from that of the neutral form.

Positive charges mean that the ion has less proton than its neutral version while negative charges mean that it has more electrons than its neutral version.

Thus, the neutral atom of lead will contain an equal number of protons as the electrons while its ionic form can have more or less than 82 protons.
