Convert the average temperatures for each collected data point given below from °C to K. Plot the average cell potentials E (y-a
koban [17]

Answer:

Explanation:

The equation of above line , y = 0.0005x+ 0.458

This can be compared with y = mx+c

Hence slope, m = 0.0005 and Y-intercept, c = 0.458

Or it can be plotted manually where straight line has to be drawn touching maximum number of data points. After drawing a straight linear line, we need to take any two points from the straight line and slope is calculated

Slope,

m = \frac{y_2-y_1}{x_2-x_1}

and y -intercept is calculated using extraplotting backwards such that it touches the Y-axis. the point where straight line touches Y-axis is Y-intercept (c).

Plot the average cell potentials E (y-axis) vs T (x-axis). image attached

What volume of 0.100 M HCl will react completely with 50.00 mL of 0.200 M NaOH?
skelet666 [1.2K]
Equation of reaction
Hcl+NaoH-->Nacl+H2O
1:1
Using the formula CaVa/CbVb=na/nb
Ca(Concentation of acid)= 0.100M
Cb(Concentration of base)=0.200M
Va=?
VB=50.00ml
na=1
nb=1
from the formula
Va= CbVbna/Canb
Va= 0.2*50*1/0.1*1
=10/0.1=100ml
Therefore volume of acid = 100ml

A chemist burns a serving of peanuts in a calorimeter and sees that 150000 j of energy is released what should the nutritional l
Sergio [31]

We know that

1 calorie = 4.184 Joules

so let us convert the joules to calories first

1 Joule = 1 / 4.184 Cal

150000 = 150000 / 4.184 Cal = 35850.86 Cal

Now in case of food articles

one calorie = 1 Kcal

Therefore on food label it will = 35.851 Cal
