Answer: 196.36990920000002
The balanced equation is:
2NaCl + 2 H2o → 2 NaOH + Cl2 + H2
1- we put 2 NaCl to balance Cl2 on the other side.
2- we put 2 NaOH to balance Na
3- We put 2 H2O to balance H & O on the to sides
Answer:
formula units
Explanation:
According to avogadro's law, 1 mole of every substance occupies 22.4 L at STP and contains avogadro's number
of particles.
To calculate the moles, we use the equation:

1 mole of
contains
of formula units
Thus 0.203 mole of
contains =
of formula units
Answer:
-k slope
The term No is the y intercept(does not mean NO) y-intercept
Explanation:
For a straight line graph, the normal equation could be written as
y = mx + c
Where m is the slope and c is the y intercept.
Writing the equation is the form of y = mx + c gives the following;
lnN = -kt + No
As obtained from the question, t is plotted in the x-axis, while lnN is the plot on the y-axis.
Now, we are asked to obtain the slope and the y-intercept. It can be seen that the slope is the coefficient of the term x in this case t. Hence, our slope is -k.
The y-intercept is the other term which in this case is No
