What mass of carbon dioxide is produced from the complete combustion of 7.30×10−3 g of methane?

Answers

Answer 1

We know that the reaction goes to completion, so all the methane will be reacted. To find the mass of carbon dioxide used, we can use the number of moles from the above equation, and the molecular weight of CO2 (= 44.009 g/mol). The mass of CO2 produced is 3.29*10^-3g.

Answer:

The mass is [tex]m = 0.0349 \ g[/tex]

Explanation:

From the question we are told that

The Henry's Law constant is [tex]k = 2.4 *10^{10} M/atm[/tex]

The volume of water is [tex]V = 525 \ ml = 0.525 \ L[/tex]

The partial pressure is [tex]P = 1.90 \ atm[/tex]

The temperature is [tex]T = 25 ^oC[/tex]

Henry's law is mathematically represented as

[tex]C = P * k[/tex]

Where C is the concentration of sulfur hexafluoride(SP)

substituting value

[tex]C = 1.90 * 2.4*10^{-4}[/tex]

[tex]C = 4.56*10^{-4} \ M[/tex]

The number of moles of SP is mathematically represented as

[tex]n = C * V[/tex]

substituting value

[tex]n = 0.525 * 4.56*10^{-4}[/tex]

[tex]n = 2.39 *10^{-4} \ moles[/tex]

The mass of SP that dissolved is

[tex]m = n * Z[/tex]

Where Z is the molar mass of SP which has a constant value of

[tex]Z = 146 g/mole[/tex]

[tex]m = 2.394*10^{-4} * 146[/tex]

[tex]m = 0.0349 \ g[/tex]

Why is tape attracted to my skin? Give explanation

Answers

Answer:

Since the tape has extra electrons, it has a negative charge. When you move your finger close to the tape, electrons in your skin are repelled and move away. This makes the skin on your finger tip have a slight positive charge. Since positive and negative attract, the tape moves toward your finger.
