Amount of charge on the test charge
Answer: helium is not a metal nor a non metal it's a noble gas
Explanation:
the rate law should be k[S2O8^-2]
The product that you obtain if you evaporate the water from the NaoH layer prior to acidifying the layer is salt of <u> para - tery-butyphenol</u>
<u><em>Explanation</em></u>
- Para-tery-butyphenol can be isolate after extracting it into NaOH solution through carrying out
- heating and then cooling,
- then 3M of HCl is added to acidify.
- Then ice bath is done if needed
- finally the precipitate is filtered.
- Para tery butyphenol can be used for production of alkylphenolic.
Answer:
0.23J/g°C
Explanation:
Given parameters:
Mass of sample = 135g
Amount of heat = 2.5kJ
Initial temperature = 19.5°c
Final temperature = 100°C
Unknown:
Specific heat capacity of the metal = ?
Solution:
The specific heat capacity of a substance is the amount of heat required to the raise the temperature of 1g of the substance by 1°C.
H = m C (T₂ - T₁ )
H is the amount of heat
m is the mass
C is the specific heat capacity
T₂ is the final temperature
T₁ is the initial temperature;
2.5 x 10³ = 135 x C x (100 - 19.5)
2500 = 10867.5C
C =
= 0.23J/g°C
