For the following experiments, identify the independent variable and the dependent variable:
faust18 [17]

Answer:

A) IV: number of hours DV: score

Explanation:

Coz,

IV- is the variable that u change

DV- is the variable that u test or measure

In this case, we need to change the hours of studying to see how studying for different hours [1 hr, 2hr, etc (( Independant variable coz we're changing the no. of hours)) ] is going to affect the student's score, and in the end, we are measuring the score of each student [this is the dependant variable].

For a particular reaction, ΔH = -144.6 kJ and ΔS = -301.2 J/K. Calculate ΔG for this reaction at 298 K.
pav-90 [236]
To calculate, I would need to know if the final answer is supposed to be in kJ or in J/K.

Either way, use the Gibb's Formula: 
ΔG= ΔH-T<span>ΔS

If the final answer is supposed to be in J/K then plug-in your values to the formula and simply solve.

However, if your final answer is supposed to be in kJ, your first step would be to convert </span>ΔS from J/K into kJ. 

This is simply done by dividing the given ΔS by 1000 ----> (-301.2/1000).<span>
(we divide by 1000 because by definition that's what a "kilo" is )

New </span>ΔS value= <span>-0.3012 kJ 

Now all you have to do is plug-in all the values into the formula. 
</span>ΔG= ΔH-TΔS
ΔG= (-144.6 kJ) - 298K(-0.3012kJ)
= -54.84 kJ 
<span>
</span>Since the ΔG is negative, this means that the reaction is spontaneous. 

Hope this helps! :)
