Answer: C ) the student’s dependent variable is the magnitude of the magnetic field that is generated
E ) the student’s independent variable is the amount of current that is being passed through the wire
Answer : The correct option is, (b) +115 J/mol.K
Explanation :
Formula used :
where,
= change in entropy
= change in enthalpy of vaporization = 40.5 kJ/mol
= boiling point temperature = 352 K
Now put all the given values in the above formula, we get:
Therefore, the standard entropy of vaporization of ethanol at its boiling point is +115 J/mol.K
"Increase Pressure " is the right answer. if you need help , let me know
Answer:
single replacement
Explanation:
If it has one plus sign it is decomposition or synthesis
however if it has two plus signs then it is single or double replacement
