Answer:
<h2>
The answer is $6.52.</h2>
Explanation:
Firstly, let's check out the given:
1. Sports Utility Vehicle's (Original SUV) avg gas mileage - 17.5 miles per gallon (mpg)
2. SUV's (Hybrid SUV) avg gas mileage - 21.5 miles per gallon (mpg)
3. Gas price - $2.59 per gallon
What is asked? How much would you save driving 237 miles in the hybrid SUV compared to the original SUV?
Next, you have to know how much gallons each car consumes upon driving 237 miles. You can do division in this step.
1. Original SUV = 237 miles ÷
= 13.54 gallons
2. Hybrid SUV = 237 miles ÷
= 11.02 gallons
Now that you know how much gallons each car consumes, you can now get the gas price for the gallons.
1. Original SUV = 13.54 gallons × $2.59 per gallon = $35.06
2. Hybrid SUV = 11.02 gallons × $2.59 per gallon = $28.54
In order to check the difference, you have to subtract.
- $35.06 - $28.54 = $6.52 (this is the amount of money that you can save driving 237 miles in the hybrid SUV compared with the original SUV)
The mass number refers to the total number of protons and neutrons which can be found in the nucleus of the atom.

Answer:
option (d) is false.
Explanation:
Acid dissociation equilibrium of HCN is represented as-

Acid dissociation constant,
, is represented as-
![K_{a}=\frac{[H^{+}][CN^{-}]}{[HCN]}](https://tex.z-dn.net/?f=K_%7Ba%7D%3D%5Cfrac%7B%5BH%5E%7B%2B%7D%5D%5BCN%5E%7B-%7D%5D%7D%7B%5BHCN%5D%7D)
where species inside third bracket represents equilibrium concentrations of respective species
So, evidently, presence of excess
(or NaCN) in solution will combine with
to produce HCN. Hence
will be larger that it would be if only the HCN solution were present.
According to Le-chatlier principle, addition of HCN will shift equilibrium towards right and addition of NaCN will shift equilibrium towards left to keep constant
value at a particular temperature.
NaOH gives acid-base reaction with HCN to produce NaCN and water. So, addition of NaOH will increase concentration of
and decrease concentration of HCN
