Given:
257J of heat
5500g of mercury
increase by 5.5
degrees Celsius
Required:
Specific heat of
mercury
Solution:
H
= mCpT
257J = (5500g of
mercury) Cp (5.5 degrees Celsius)
Cp = 8.5 x 10^-3
Joules per gram per degree Celsius
<span>A ) AB is a compound . Ionic compound because the electronegativity differs a lot in both !
</span><span>
B) Same
C ) Compound . But the bond between them is covalent .
D ) AB is an ionic compound . A is the cation and B is the anion </span>
When two atoms are bonded together, the atom that is LEAST likely to attract electrons to itself is
the atom with the smallest electronegativity
Answer:

Explanation:
Hello!
In this case, considering that the Gay-Lussac's law allows us to relate the temperature-pressure problems as directly proportional relationships:

Thus, for the initial pressure and temperature in kelvins the final temperature in kelvins, we compute the final pressure as:

Best regards!
B) It will accelerate to the right because 500 N> 300 N
