Answer:
The answer is D.
Explanation:
I learned about this last year. Its very simple if you let your parents or teachers explain it to you!
<span>hexa stands for 6, so this molecule has 1 sulfur atom, surrounded by 6 fluorine atoms.</span>
Answer:
Saturated hydrocarbons have one single bonds not double or triple.
Alkanes family are saturated.
Alkenes and Alkynes are double and triple.

Answer:
The answer to your question is: Neutral
Explanation:
A neutral solution is a solution whose pH is 7.
That means that this solution has the same amount of H⁺ and OH⁻.
Examples of neutral solutions:
- distilled water
- sugar solution
- table salt
- cooking oil.
Answer:
0.323
Explanation:
number of moles of Ca(OH)2(s) = mass given / molar mass = 0.350 g / 74.093 g/mol = 0.00472 mol
number of mole of HNO3 = Molarity × volume in Liters = 1.0 × (45 / 1000) = 0.045 M
Ca(OH)2(s) + 2 HNO3(aq) → Ca(NO₃)₂(aq) + 2 H₂O(I)
1 mole of calcium hydroxide react with 2 mole of trioxonitrate(V)
0.00472 mole will require 0.00945 mole
but we have 0.045 mole of the acid
net mole = 0.045 - 0.00945 = 0.0356 mole
Molarity of the net mole = 0.0356 / (75/1000) = 0.475 M
pH = - log (0.475) = 0.323
