Answer:
Energy absorbed by <u>Iron block</u> E (iron) = 460.5 J
Energy absorbed by <u>Copper block</u> E (Copper) = 376.8 J
Explanation:
To find the heat absorbed, we can use the formula as,
<em>q = m c ΔT</em>
Here, Mass = m = 10 g = 0.01 kg
ΔT = change in temperature = 400 - 300 = 100 K = 100 - 273 = -173 °C
c = specific heat capacity
c for iron = 460.5 J/kg K
c for copper = 376.8 J/kg K
Plugin the values in the above equation, we will get,
<em>q (iron) = 0.01 kg × 460.5 J/kg K × 100 K = 460.5 J</em>
<em>q (copper) = 0.01 kg × 376.8 J/kg K × 100 K = 376.8 J</em>
CH₄ + 2O₂ ---> CO₂ + 2H₂O
16g..................................18g×2
16g CH₄ --- 36g H₂O
5,1g CH₄ --- X
X = (5,1×36)/16
X = 11,475g H₂O
Answer:
a. True
Explanation:
In this reaction, we will have a <u>hydride transfer</u> to the carbon of the carbonyl group, moving the electrons of the double bond towards the oxygen producing a negative charge. The double bond is then regenerated by removing the chlorine atom from the molecule, producing an <u>aldehyde.</u>
Then, another molecule the LiAlH4 transfers another <u>hydride</u> to the carbon of the carbonyl group, again producing a negative charge on the oxygen. Finally, the hydrogen is protonated producing a <u>primary alcohol.</u>

No the law of cross cutting relates to all somewhat horizontal. The law of cross cutting is the logical assumption that a magma protrusion that cuts through horizontal layers at a diagonal or vertical is younger than the layers that it cuts through.
Sedimentary rocks are most often found in horizontal or near horizontal layers or strata. Therefore cross cutting can be used most often in the relative dating of sedimentary rocks.
However lava flows also form horizontal layers of rock. Pumice ash can be laid down in horizontal layers. A magma protrusion can also be used to relative date igneous layers of rock
