What is the balanced equation that represents the reaction between hydrogen and nitrogen to make ammonia (NH3)?

Final answer:

You can wrap your sandwich in Tin, an element from the periodic table.

Explanation:

The periodic table is a chart that organizes all known elements based on their atomic number, symbol, and atomic mass. To wrap a sandwich, you can use the element Tin, which has the atomic symbol Sn and atomic number 50. Tin is a soft, malleable metal that is often used as a coating for other metals to prevent corrosion. It can be melted and shaped into thin sheets, making it suitable for wrapping a sandwich.

Final answer:

The pun answer to the question 'what do you wrap your sandwich in?' is 'Aluminum', because aluminum is an element from the periodic table and aluminum foil is often used to wrap sandwiches.

Explanation:

The pun in this question refers to an element from the periodic table to humorously answer the question "What do you wrap your sandwich in?". One possible response could be: "You wrap your sandwich in Aluminum", since the word "wrap" is commonly associated with aluminum foil, which is used to wrap and protect food, like a sandwich. Aluminium is a chemical element in the periodic table with the symbol Al and atomic number 13. It's a silvery-white, soft, non-magnetic and ductile metal, which makes it ideal for creating thin, flexible sheets like aluminum foil for food wrap.

Answer:

This question is incomplete but the completed question is below

What is used up in and stops a chemical reaction? (a) percent yield (b) limiting reactant (c) theoretical yield (d) excess reactant

The correct option is (b)

Explanation:

A chemical reaction is a chemical combination,rearrangement or disintegration of chemical substance(s) (called reactants) to form new chemical substance(s) (called products).

A limiting reactant is the reactant that is totally used up during the course of a reaction. When this reactant is used up, it limits the amount of products formed and eventually stops the chemical reaction.

Hi

The chemical reaction does not stop until the reagent is used .

I hope that's help !

Answer:

             Option-B (Carbon and Silicon)

Explanation:

                  Among the given pairs only carbon and silicon have the most similar properties. This is because,

Sodium and Magnesium belong to different groups. Sodium present in Group I has one electron in its valence shell and capable of transferring only one electron while, Magnesium present in Group II have two electrons in its valence shell and is capable of donating two electrons. Hence, both show different properties.

Example:

                                           2 Na  +  Cl₂    →     NaCl

                                           Mg  +  Cl₂    →    MgCl₂

As shown in reactions when Sodium and Magnesium are treated with Cl₂ they give a products with different proportions.

Carbon and Silicon show almost same properties because both belong to Group IV hence both are capable of forming four bonds. Also, they share the same property of self linkage in making a long chains.

Argon and Chlorine also belong to two different groups. Argon is present in Group VIII (Noble Gases) and Chlorine is present in Group VII (Halogens). Hence, Argon is an inert specie which is non reactive while Chlorine gives different reaction easily.

Potassium and Calcium belong to different groups. Potassium present in Group I has one electron in its valence shell and capable of transferring only one electron while, Calcium present in Group II have two electrons in its valence shell and is capable of donating two electrons. Hence, both show different properties.

Example:

                                           2 K  +  Cl₂    →     KCl

                                           Ca  +  Cl₂    →    CaCl₂

As shown in reactions when Potassium and Calcium are treated with Cl₂ they give a products with different proportions.

Answer;

The above statement is false

Explanation;

Photosynthesis is the biological conversion of light or electromagnetic energy from the Sun into chemical energy. It occurs in green plants, algae, and some types of bacteria, and requires a series of biochemical reactions.

In photosynthesis, carbon dioxide and water react with one another in the presence of light and a chemical known as chlorophyll to produce a simple carbohydrate and oxygen.

Fossils of what are thought to be filamentous photosynthetic organisms have been dated at 3.4 billion years old. Geological evidence suggests that oxygenic photosynthesis, such as that in cyanobacteria, became important during the Paleoproterozoic era around 2 billion years ago.

I put true into the answer and it was wrong so it is actually FALSE.

The answer above is incorrect.
