Answer:
c = 0.39 J/g.°C
Explanation:
Given data:
Energy required = 242.2 J
Mass of copper = 81.6 g
Initial temperature = 27.5°C
Final temperature = 35.2°C
Specific heat capacity of copper = ?
Solution:
Specific heat capacity:
It is the amount of heat required to raise the temperature of one gram of substance by one degree.
Formula:
Q = m.c. ΔT
Q = amount of heat absorbed or released
m = mass of given substance
c = specific heat capacity of substance
ΔT = change in temperature
ΔT = 35.2°C - 27.5°C
ΔT = 7.7°C
242.2 J = 81.6 g ×c × 7.7°C
242.2 J / 81.6 g = c × 7.7°C
c = 3 J/7.7g.°C
c = 0.39 J/g.°C
Answer:
It all depends what your working with and what experiment your planning on doing .
Explanation:
Say if you were working with chemicals you would the tools that would help you protect your body like gloves,googles, apron , etc
So in conclusion it depends what your doing to know what tools you are going to need
Chemical Compound- a chemical substance consisting of 2 or more different chemically bounded chemical elements with a fixed ratio determining the composition. It is commonly used for electricty
Answer:
if you’re looking for a balanced equation it would be:
Methanol +ethanoic acid ==> methyl ethanoate + water ( in the presence of concentrated sulfuric acid )
CH3OH + CH3COOH==> CH3COOCH3 + H2O
~~~~~~
But, if you were looking for what it would be called it would be:
ethanoic acid with methanol will produce methyl ethanoate.
~~~~~~
And the reaction between Methanol and Ethanoic acid is known as esterification.
~~~~~~
I wasn’t sure of your question so I answered the best way that I could. I hope this helped!
