Determine the volume of the product containing carbon produced when 15.0 g of C2H2 are reacted with an excess of oxygen gas

Answers

Answer 1

Answer:

25.8 L

Explanation:

Step 1: Write the balanced equation for the complete combustion of acetylene

C₂H₂ + 2.5 O₂ ⇒ 2 CO₂ + H₂O

Step 2: Calculate the moles corresponding to 15.0 g of C₂H₂

The molar mass of C₂H₂ is 26.04 g/mol.

15.0 g × 1 mol/26.04 g = 0.576 mol

Step 3: Calculate the moles of CO₂ produced from 0.576 moles of C₂H₂

The molar ratio of C₂H₂ to CO₂ is 1:2. The moles of CO₂ produced are 2/1 × 0.576 mol = 1.15 mol.

Step 4: Calculate the volume corresponding to 1.15 moles of CO₂

At standard temperature and pressure, 1 mole of CO₂ occupies 22.4 L.

1.15 mol × 22.4 L/1 mol = 25.8 L

Consider the table below that summarizes the types of materials that can block the 3 different types of radiation. Based on the table, at which numbered spot in the table does each type of radiation belong. 1 = beta; 2 = alpha, 3 = gamma

Answers

Answer:

D. 1 = gamma; 2 = alpha, 3 = beta

Explanation:

I apologize if this answer is late, but I got answered the question right on my "Types of Radioactive Decay" quiz :)

Hope this is helpful for others! :D

Based on the table, the type of radiation belong from 1 is the gamma rays, from 2 is the aplha rays and from 3 is the beta rays.

What are radiations?

During the radioactive decay process, some amount of energy is released in the form of particles and that radiations will known as alpha rays, beta rays and gamma rays.

Gamma ray are mare energetic rays and will shielded by only lead and thick concrete materials.Beta rays are less energetic than gamma rays and will shielded by lead, cloth, paper, wood, aluminium foil and thick concrete materials.Aplha rays have very less amount of energy in it and it will be shielded by all above mention materials.

Hence 1 is the gamma rays, 2 is the aplha rays and 3 is the beta rays.

reacted?

Answers

Answer:

36.5 g CO2

Explanation:

First, Write a Balanced Equation  

C   + 2 ZnO → CO2  + 2 Zn

Useful Information,  

MW of ZnO = 81.41 g

MW of CO2 = 44.01 g

135 g ZnO x (1 mol ZnO /  81.41 g ZnO) x (1 mol CO2/2 mol ZnO) x ( 44.01 g CO2 / 1 mol CO2 ) = 36.5 g CO2

When Svante Arrhenius first proposed his acid base theory, he was a doctoral candidate. His professors thought his ideas were unfounded. Within a decade, the Arrhenius theory of acid base was widely accepted and praised within the scientific world. Arrhenius defined acids as compounds having an ionizable hydrogen and bases as compounds with ionizable hydroxides. Eventually scientists adopted a broader theory which includes more compounds to define acids and bases. The Bronsted-Lowry acid base theory defines an acid as a _______ and a base as a ______________.

Answers

Answer:

proton donar

proton acceptor

Explanation:

From the given information of the question, Arrhenius acid and base concept is explained, from which a better term to define an acid and base is defined, known as The Bronsted-Lowry acid base theory.

According to The Bronsted-Lowry acid base theory -

An acid is the species which can readily donate a proton, where as, a base is the species, which can readily accept a proton.

Hence, the correct answer is as follow -

proton donar

proton acceptor

Answer:

Explain one way that you could lower the amount of trash that your family produces. Be specific in your example. Explain how it will actually lead to a lower amount of trash

Answers

To lower the amount of trash my family produces, we can use reusable bottles, cutlery, and dishes. This would be a better alternative to using both paper, and plastic items which would increase trash output. Reusable items like dishes can be used multiple times without throwing them away, instead of having to use plastic items that we’d throw away after using once.
