I hope this helps in some way. I forgot to mention that the question states they want to find THE NUMBER OF MOLES for H2O. Yherefore, you would want mol of H2O on top.
D) Attraction between oppositely-charged ions.
In ionic bonds, one atom is negatively charged, and one atom is positively charged. The positively charged atom gives its electrons, and the negatively charged atom receives the electrons--thus, the opposite charge attracts them to one another and holds them together. That simple.
Answer:
faster, and the ingredient will be a liquid.

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)
Answer: C. a compound in which one or more carbon atoms have double or triple bonds.
Explanation:
Saturated hydrocarbons are defined as the hydrocarbons in which single bond is present between C-C atoms. The general formula used for these hydrocarbons is . Example:
Unsaturated hydrocarbons are defined as the hydrocarbons which have double or triple covalent bonds present between carbon and carbon atoms. They are known as alkenes and alkynes respectively. The general formula used for these hydrocarbons is and respectively. Example:
Both the hydrocarbons are not soluble in water as they are non polar in nature unlike water which is polar.
Cycloalkanes are also saturated hydrocarbons as single bond is present between C-C atoms.
Thus the correct statement is An unsaturated hydrocarbon is a compound in which one or more carbon atoms have double or triple bonds.
