Answer:
Moment=Force x Pivot
Explanation:
A moment is the turning effect of a force. Moments act about a point in a clockwise or anticlockwise direction.
Law of moments:
When an object is balanced (in equilibrium) the sum of the clockwise moments is equal to the sum of the anticlockwise moments.
How to calculate moments:
Moment=Force x Pivot
Answer:
Explanation:
Hello,
In this case, for the acid dissociation of formic acid (HCOOH) we have:
Whose equilibrium expression is:
![Ka=\frac{[H^+][HCOO^-]}{[HCOOH]}](https://tex.z-dn.net/?f=Ka%3D%5Cfrac%7B%5BH%5E%2B%5D%5BHCOO%5E-%5D%7D%7B%5BHCOOH%5D%7D)
That in terms of the reaction extent is:
Thus, solving for 
which is also equal to the concentration of hydrogen ions we obtain:
![[H^+]=0.00528M](https://tex.z-dn.net/?f=%5BH%5E%2B%5D%3D0.00528M)
Then, as the pH is computed as:
![pH=-log([H^+])](https://tex.z-dn.net/?f=pH%3D-log%28%5BH%5E%2B%5D%29)
The pH turns out:

<span>67.2 minutes
First convert the runner's speed from mi/h to km/h by multiplying by 1.60934 km/mi, giving
7.1 mi/h * 1.60934 km/mi = 11.43 km/h
Divide the distance by her speed.
12.8 km / (11.43 km/h) = 1.12 h
Convert hours to minutes by multiplying by 60
1.12 h * 60 min/h = 67.2 min</span>
True!
For example:
The atomic mass of carbon is 12.011 (i think) and the weight of carbon is 12. But with C13 and C14 being a little higher, it makes the average higher. Random fact: C14 is used for carbon dating.
