Both respiration and combustion can produce carbon dioxide. Therefore, of the answers in your list only the third one is correct.
LenaWriter [7]3 years ago

Answer:  Both release carbon dioxide into the atmosphere.

Explanation:  Combustion is a process  which releases carbon dioxide and water in the presence of oxygen .

For eg-   Combustion of methane in presence of oxygen will lead to the release of the carbon dioxide and water.

               CH_{4} + O_{2}\rightarrow CO_{2} + H_{2}O

Respiration is the process taking place in living organism which involves the production of the energy. It is mainly proceeded in the body through lungs with the intake of the oxygen and release of the carbon dioxide.

The term used to describe the rapid release of bubbles from a liquid is _____
aksik [14]
The term used to describe the rapid release of bubbles, or rapid release of a gas from a liquid or a solution is called Effervescence.  The bubbling of a solution is due to the escape of a gas which may be from a chemical reaction, as in fermenting liquid, or by coming out of a solution after having been under pressure, as in a carbonated drink. For example; soda, champagne among others.

A sample of gas in a balloon has an initial temperature of 21 ∘C and a volume of 1310 L . If the temperature changes to 70 ∘C ,
bixtya [17]

Answer:

1528.3L

Explanation:

To solve this problem we should know this formula:

V₁ / T₁ = V₂ / T₂

We must convert the values of T° to Absolute T° (T° in K)

21°C + 273 = 294K

70°C + 273 = 343K

Now we can replace the data

1310L / 294K = V₂ / 343K

V₂ = (1310L / 294K) . 343K → 1528.3L

If the pressure keeps on constant, volume is modified directly proportional to absolute temperature. As T° has increased, the volume increased too

What are valence electrons and how do they affect the properties of an atom?
vlada-n [284]

The term "valence electrons" refers to all of the electrons in an atom's outermost shell.

The centre of the atom is where the nucleus is. The nucleus contains protons and neutrons. The electrons travel in a specific circular direction and at a specific distance from the nucleus.

The atom's final shell's electrons take part in chemical reactions and the production of bonds. Both ionic and covalent bonding involve valence electrons. Metals are elements with one, two, or three electrons in their final shell.

These substances become positive ions after losing their electrons. Non-metals are substances with 5, 6, or 7 electrons in the outermost shell. These substances all gain electrons and change into negative ions.

Ionic bonds are those created by the transfer of electrons between metals and non-metals. For instance, ionic bonding allows sodium and chlorine to interact to generate sodium chloride.
