Answer:
The answer to your question is: 1, 2, 1, 2
Explanation:
1 Fe(s) + 2 Na⁺(aq) → 1 Fe²⁺(aq) + 2 Na(s)
Fe⁰ - 2e⁻ ⇒ Fe⁺² Oxidases
Na⁺ + 1 e⁻ ⇒ Na⁰ Reduces
1 x ( 1 Fe⁰ ⇒ 1 Fe⁺²) Interchange number of
2 x ( 2Na⁺ ⇒ 2 Na⁰ ) electrons
To balance the oxidation-reduction reaction Fe(s) + Na+(aq) → Fe2+(aq) + Na(s), follow these steps: balance atoms other than hydrogen and oxygen, balance hydrogen atoms, balance oxygen atoms, verify charges
To balance the oxidation-reduction reaction Fe(s) + Na+(aq) → Fe2+(aq) + Na(s), we need to balance the number of atoms for each element and the total charge on both sides of the reaction. Here's the step-by-step process:
So, the balanced oxidation-reduction reaction is: Fe(s) + 2Na+(aq) → 2Fe2+(aq) + Na(s).

In chemistry, elements and compounds are classified as chemical substances. Elements are substances composed of identical atoms, whereas compounds are substances formed from chemically bonded elements.
In the world of chemistry, both elements and compounds are classified as chemical substances. An element is a substance composed of identical atoms, such as hydrogen or iron. A compound, on the other hand, is a substance formed when two or more elements are chemically bonded together, like water (H2O) or carbon dioxide (CO2). It's important to distinguish these from mixtures and solutions, which can contain multiple substances but aren't chemically bonded, therefore, they are not considered chemical substances in the strict sense.

I won't give you the answer, but I will give you the process and then you can plug in the numbers. I'm guessing you are looking for how many MOLES are in 63.658g of Carbon. What you need to do to solve this is to use the molar mass of Carbon plugged into the dimensional analysis process. That might sound confusing, so let me give you a sample question.
Now, you plug in the numbers in your problem into that sample process. And if you don't know where to find the molar mass, it's simple.
The Molar mass of an element is the same as the atomic mass. So Hydrogen has the atomic mass of 1.01u, and it also has the molar mass of 1.01 grams per mole.

Answer:
I kinda forgot. I'm sorry if I didn't answer your question.
Explanation:
(2) Aluminum reacts with sulfuric acid.
(3) Aluminum conducts an electric current.
(4) Aluminum has a density of 2.698 g/cm3 at STP.
The correct answer as to which statement describes a chemical property of aluminum would be that it reacts with sulfuric acid.
There are two properties of every substance - physical and chemical properties.
Physical properties refer to the characteristics that can be observed without altering the substance while chemical properties refer to the characteristics of undergoing chemical changes in reactions.
Physical properties include color, boiling and melting point, hardness etc., while chemical properties include reactivity, toxicity, flammability, etc.
All the options have to do with physical properties of aluminum except its reactivity with sulfuric acid. The equation of reaction is as follows:
Al + H2SO4 ---> Al2(SO4)3 + H2

State, in terms of the relative activity of elements, why this reaction is spontaneous.
The reaction depicted by the equation would be spontaneous because Mg is higher in reactivity than H.
The reactivity series of anions is such that: K, Na, Ca, Mg, Al, Zn, Fe, Sn, Pb, and H.
Ions at the higherposition in the reactivity series are able to displace those in lower positions in chemical reactions. Whereas, those in lower positions cannot displace those in higher positions.
Mg is far higher than H in the reactivity series, and thus, will be able to displace Hfrom HCl without any forceful procedure.
