Answer:Re3(PO4)2 I think I'm wrong
Explanation:
The data provided is of specific heat
The relation between specific heat, heat absrobed and temperature change is
Q = mass of substance X change in temperature X specific heat
Now if we have provided same amount of heat to two substances of different specific heat, the substance with lower specific heat will heat up more as compared to the substance with higher specific heat.
[Specific heat is the amount of heat absorbed by a substance (say nickel) to raise it temperature by one degree if we have taken one gram of substance]
Higher the specific heat higher the heat required to raise the temperature upto same extent.
Thus as the specific heat of Nickel is less, it will heat up easily
Answer: Granite, because it needs to absorb more energy to increase its temperature
Answer:
2–
Explanation:
Oxygen is in the 6th group originally has a charge of 1–, but when oxygen gets two electrons added to make it a stable gas configuration of s2 p6 it changes it to 2– to form an oxide ion
The question is incomplete, the complete question is;
Indicate which reaction will occur faster. Explain your reasoning. Select the single best answer Hexyl chloride or cyclohexyl chloride with sodium azide in aqueous ethanol O Cyclohexyl chloride reacts faster because it is more soluble in the solvent OHexyl chloride reacts faster because it is less sterically hindered. O Cyclohexyl chloride reacts faster because its carbocation intermediate is more stable. Hexyl chloride reacts faster because hydrogen abstraction is more likely to occur in this compound.
Answer:
Hexyl chloride reacts faster because it is less sterically hindered.
Explanation:
Now we have to think through the problem carefully. We must remember that the azide ion is a good nucleophile. Being a good nucleophile, we should be thinking about an SN2 reaction mechanism.
Though ethanol is a polar protic solvent which may weaken the nucleophile by hydrogen bonding, the nucleophile will still react very fast with a primary alkyl halide such as hexyl chloride via SN2 mechanism.
The substrate is easily accessible to the azide ion in hexyl chloride compared to cyclohexyl chloride hence hexyl chloride reacts faster than cyclohexyl chloride.
8.4 grams. I think but I’m not 100% sure
