If a negatively charged object is brought near a neutrally charged sphere, what will happen? The electrons will move toward the

charged object. The protons will jump to the negatively charged object making both objects neutral. The electrons will jump to the charged object. The electrons will move away from the charged object.

The protons will jump to the negatively charged object making both objects neutral.

Sidana [21]3 years ago

Answer: Option (a) is the correct answer.

Explanation:

When a charged object is brought near a neutral atom then the neutral atom will develop an opposite charge. This process of inducing charge is known as induction.

Hence, when a negatively charged object is brought near a neutrally charged sphere then a positive charge will develop at the sphere. Thus, there will be attraction because opposite charges attract each other and like charges repel each other.

Hence, we can conclude that if a negatively charged object is brought near a neutrally charged sphere, then the electrons will move toward the charged object.

Having done the experiment, explain briefly how the mass of zinc not equal the mass of lead gained (hint: the periodic table)
masya89 [10]

Answer:

Due to the difference in the relative atomic masses and therefore, the molecular masses of Zn and Pb, one mole of Zn is about 3.2 times lighter than one mole of Pb

Explanation:

From the periodic table, we have;

The atomic number of zinc, Zn = 30

The atomic mass of zinc, Zn = 65.38 amu

The molar mass of zinc, Zn = 65.38 g/mol

The atomic number of lead, Pb = 82

The atomic mass of lead, Pb = 207.2 amu

The molar mass of lead, Pb = 207.2 g/mol

Therefore, whereby equal number of moles of Zn is lost and Pb is gained, we have;

Mass of 1 mole of Zn = 65.38 grams

Therefore, 1 gram of Zn = 1/65.38 moles = 0.0153 moles

0.12 grams of Zn = 0.12×0.0153 = 0.00184 moles of Zn

Given that equal number of moles of Zn and Pb are involved in the reaction, the number of moles of Pb gained = 0.00184 moles

The mass of Pb gained = Number of moles of Pb gained × Molar mass of Pb

The mass of Pb gained = 0.00184 × 207.2 = 0.38 g ≈ 0.4 g.

Amount of Pb gained = 0.43 g ≈ 0.4 g

The component which dissolves in a solution is called the?
VladimirAG [237]

The correct answer is Solute

Explanation:

In chemistry, a solution refers to a homogenous mixture of two substances that occurs through dissolution, this means once they are mixed the substances form a uniform new substance and cannot be easily separated. Additionally, in chemistry, the substances involved in a solution are either classified as solutes if they are the substances that dissolve to form a solution or as solvents in the case of substances in which the solute dissolves in. For example, if you mix salt and water, the salt acts as the solute while the water is the solvent. Thus, the component which dissolves in a solution is called the solute.
