Answer:

A) a plant

Explanation:

  • A plant cell consists of cytoplasm, chloroplast, nucleus, mitochondria, cell wall, and a Golgi apparatus. They represent a eukaryotic cell of green plants and there are various types of plant cells such as Parenchyma, Collenchyma, Sclerenchyma,  Xylem, Phloem, and the Epidermis.

In a lab, silver nitrate,AgNO₃, is dissolved in water until no solid is observed in the container. Then, a solution of sodium ch
leva [86]

Answer:

The answer to your question is: A, C, E

Explanation:

After reading the information given, we can conclude that both reactants react to form a new solid product and another product that do not precipitate.

The reaction is:

                         AgNO₃ + NaCl   ⇒      AgCl  +  NaNO₃

a. Formation of a solid indicates that a chemical reaction occurred  This option is correct, precipitation indicates that a changed occurred in the solution due to a chemical reaction.

b. The initial disappearance of silver nitrate in water indicates a chemical reaction occurred  No, what is happing is that silver nitrate is dissolving in water, this process is a physical change because matter do not change its nature.

c. The color change of the solution indicates a chemical reaction occurred  This option is true, when a color appears suggest the formation of a new product.

d. A chemical reaction occurred when silver nitrate was added to water

This option is not correct, in this process silver nitrate is dissolving in water but it is not a chemical reaction because matter does not change is nature.

e. A chemical reaction occurred when the solutions were combined  This option is true because silver nitrate and sodium chloride react to form a new product (solid formation and change in color).

f. The lack of temperature change indicates a chemical reaction didn't occur This is false, some reactions do not need a change of color to happen.

Q#5 Balance and list the coefficients from reactants to products.
skad [1K]

A. 2Fe_2O_3(s) +3C(s) → 4Fe(s) + 3CO_2(g)

B. 2Al(s) + 3FeO(s) → Fe(s) + 3Al_2O_3(s)

C. 2Al(s) +3H_2SO_4(aq) → Al_2(SO_4)_3(aq) + 3H_2(g)

What is a balanced chemical equation?

An equation that has an equal number of atoms of each element on both sides of the equation is called a balanced chemical equation.

A. 2Fe_2O_3(s) +3C(s) → 4Fe(s) + 3CO_2(g)

B. 2Al(s) + 3FeO(s) → Fe(s) + 3Al_2O_3(s)

C. 2Al(s) +3H_2SO_4(aq) → Al_2(SO_4)_3(aq) + 3H_2(g)

Given the balanced ionic equation representing the reaction in an operating voltaic cell: zn(s) + cu2+(aq) → zn2+(aq) + cu(s) th
soldi70 [24.7K]

Answer: from the Zn anode to the Cu cathode


Justification:


1) The reaction given is: Zn(s) + Cu₂⁺ (aq) -> Zn²⁺ (aq) +Cu(s)


2) From that, you can see the Zn(s) is losing electrons, since it is being oxidized (from 0 to 2⁺), while Cu²⁺, is gaining electrons, since it is being reduced (from 2⁺ to 0).


3) Then, you can already tell that electrons go from Zn to Cu.


4) The plate where oxidation occurs is called anode, and the plate where reduction occus is called cathode.


So you get that the electrons flow from the anode (Zn) to the cathode (Cu).


Always oxidation occurs at the anode, and reduction occurs at the cathode.
