How does an object become negatively charged?

Chemistry

neonofarm [45]3 years ago

It gains electrons. Electrons are negatively charged subatomic particles; so when an atom gains an electron it becomes net negative.

Paha777 [63]3 years ago

<u>Answer:</u> The correct answer is it gains electrons.

<u>Explanation:</u>

There are 3 subsatomic particles in an atom: Electrons, neutrons and protons.

Neutrons does not carry any charge on them. They are neutral particles.

Protons carry positive charge on them.

Electrons carry negative charge on them.

In an element, number of protons and electrons remains the same.

When an element looses electrons, the number of protons increases than electrons. Thus, the element will have a positive charge.

When an element gains electrons, the number of electrons is more than the number of protons. Thus, the element will have a negative charge.

Hence, the correct answer is it gains electrons.

A 1.00 L of a solution is prepared by dissolving 125.6 g of NaF in it. What would be the molarity of this solution?
DedPeter [7]

Answer:

2.99 M

Explanation:

In order to solve this problem we need to keep in mind the definition of molarity:

  • Molarity = moles of solute / liters of solution

In order to calculate the moles of solute, we <u>convert 125.6 g of NaF into moles</u> using its <em>molar mass</em>:

  • 125.6 g NaF ÷ 42 g/mol = 2.99 mol NaF

As the volume is already given, we can proceed to <em>calculate the molarity</em>:

  • Molarity = 2.99 mol / 1.00 L = 2.99 M

Why is a typical car battery in a car is filled with a solution of sulferic acid
Lesechka [4]

Answer:

Sulfuric acid has a higher density than water, which causes the acid formed at the plates during charging to flow downward and collect at the bottom of the battery.

Which bond has the greatest ionic character? A) H-Cl B) H-F c) H-O d) H-N
Len [333]
 I really hope that this helps.  H-F because the difference in electronegativity is the greatest, about 1.9 on the Pauling scale. The term means which bond has the greatest polarity and is thus most similar to an ionic bond, which involves the transfer of an electron (in opposition to covalent bonds, which share electrons). It is H-F because out of all the atoms here bonded with H, ie hydrogen, F is the most electronegative which means it can pull the bonded electrons to itself more than can Cl, O, and N. <span>That means a stronger polarization of the electron cloud forming the bond with hydrogen and therefore a stronger ionic character.</span>

At PO2 = 40 mm Hg, which statement about the saturation of either myoglobin (Mb) or hemoglobin (Hb) is true? At PO2 = 40 mm Hg,
Damm [24]

Answer:

At this partial pressure of oxygen, Mb would be almost completely saturated but Hb would not.  

Explanation:

The oxygen saturation curves for Mb and Hb are quite different. The curve for Mb is hyperbolic while that for Hb is sigmoidal.

Mb reaches oxygen saturation before Hb.

Thus, at a partial pressure of 40 mmHg, Mb is almost completely saturated but Hb is not.
