Answer:
The independent variable is the type of material
The dependent variable is the thermal energy transferred by that material
Explanation:
The type of material is independent of the heat flowing through it. While the thermal energy transferred is surely dependent on the material through which it transfers.
Answer:
1–ethoxybutane
Explanation:
In naming the above compound, the following must be observed:
1. The longest chain gives the root name of the compound.
2. The shorter chain is named as substituent together with the oxygen group as alkoxy.
3. Locate the position of the alkoxy group by giving it the lowest low count.
4. Combine the above to obtain the name of the compound.
Now we shall name the compound as follow:
1. The longest chain is carbon 4 i.e butane.
2. The shortest chain is ethyl (i.e –CH₂CH₃). This is named together with the oxygen atom as ethoxy.
3. The ethoxy group is located at carbon 1 of the butane chain since it is the functional group of the chain.
4. The name of the compound is:
1–ethoxybutane.
Antarctic soils exist, in general, they comprise a surface pavement (i.e., a layer of gravel, stones or boulders formed largely by weathering and the removal of fine materials mainly by wind action) and a seasonally thawed active layer over permafrost.
Answer:
The value of K at this temperature = 2.25
Explanation:
According to question the equilibrium reaction is
H₂(g) + I₂(g) ⇄ 2 HI(g)
Initial concentration 2 2 8
At equilibrium 2 + 2x 2 + 2x 8 - 2x
At equilibrium concentration of HI changes to become 6 Molar
So 8 - 2x = 6
or, x = 1
So concentration of H₂ = 2 + 2 x 1 = 4 molar
concentration of I₂ = 2 + 2 x 1 = 4 molar
Kc =
⇒ Kc =
⇒ Kc = = 2.25
