How many moles of copper are formed when 3.8 moles of zinc are mixed with copper (II) sulfate?

Answers

Answer 1
Answer: CuSO₄+ Zn = Cu + ZnSO₄

1 mole Zn ---------> 1 mole Cu
3.8 mole Zn ------> ?

moles Cu = 3.8 x 1 / 1

= 3.8 moles of Cu

hope this helps!
Answer 2
Answer:

Final answer:

When 3.8 moles of zinc are mixed with copper (II) sulfate, the same number of moles of copper will be formed.

Explanation:

To determine the number of moles of copper formed when 3.8 moles of zinc are mixed with copper (II) sulfate, we need to consider the balanced chemical equation for the reaction.

Zn + CuSO4 → Cu + ZnSO4

The stoichiometry of the reaction tells us that 1 mole of zinc reacts with 1 mole of copper sulfate to produce 1 mole of copper. Therefore, if 3.8 moles of zinc are mixed with copper sulfate, the same number of moles of copper will be formed.

Knowledge of atomic structure has evolved over time. Thomson discovered that atoms contain electrons, Rutherford discovered that most of the mass of an atom is concentrated in its center, and Bohr discovered that electrons orbit the nucleus. Taken together, what do these discoveries demonstrate

Answers

 J.J. Thompson's plum pudding model was devised after thediscovery of electron but before the discovery of the nucleus of the atom.Rutherford, who overturned Thompson's plum pudding model proposed that onhis experiment (Rutherford model) he discovered that the atom has a tiny, heavynucleus, which is named as nucleus of the atom. While the most important properties of atomic and molecular structure was explained using the simple [picture ofan atom called the Bohr Model. This model was proposed by Niels Bohr. He alsoconcluded that an atom is a small, positively charged nucleussurrounded by orbiting electrons.  Thedifferent theories and discoveries  by the great scientists mentioned abovedemonstrate the atomic model and composition of atoms.

Mg(s) + 2HCl(aq) mc019-1.jpg H2(g) + MgCl2(aq)What is the most likely effect of an increase in pressure on this reaction?



The reactant surface area increases.

The reaction rate decreases.

The reaction is not affected at all.

The reaction stops completely.

Answers

The increase in pressure alters the equilibrium of the reaction. In this case, the number of gaseous products in the reactant side is zero while the product side contains 1 gaseous product. The increase in pressure favors the side with less number of gaseous molecules which is the reactant side. Hence, the reaction rate decreases.

How are ions Formed?

Answers

Answer & explanation:

For an atom to be electrically neutral, it must have the same amount of protons and electrons, but this does not always happen, so compounds called ions arise.

Ions are formed when an atom of an element has electron gain or loss due to reactions. They can be classified into cations and anions.

Anions are atoms that receive electrons, so they are negatively charged.

Examples: Cl⁻, O⁻², N⁻³

Cations are atoms that lose electrons and thus become positively charged.

Examples: Na⁺, Al⁺³, Pb⁺⁴

In addition, some compounds are formed in bonds between negative and positive ions. These are called ionic bonds.

Example: Formation of sodium chloride (table salt).

Na⁺ + Cl⁻ → NaCl
Ions are formed when atoms lose or gain electrons in order to fulfill the octet rule and have fuller valence electron shells.
