Vinegar is an acid. Based on
what you know about the
properties of acids and bases,
which would you expect from
vinegar?
A. It should feel slippery.
B. It will release OH-in water.
C. It will release H+ in water.
Answers
Answer:
C
Explanation:
Acids contain H plus ions. When within a solution or neutralised these ions are released.
The substance which gives H+ ion are called as acid. Vinegar is an acid because it will release H+ in water. Therefore, option C is correct.
What is vinegar ?Acetic acid and water are combined to create vinegar through a two-step fermentation process. First, yeast consume any liquid derived from a plant source, such as fruits, whole grains, potatoes, or rice, and feed on the sugar or starch therein. It ferments into alcohol.
White vinegar typically contains 93–96% water and 4-7% acetic acid. It can be used to cook, bake, clean, and control weeds. It may also help with weight loss and decrease cholesterol and blood sugar levels.
The sugar is converted to ethanol (ethyl alcohol) by yeast and bacteria in a two-step fermentation process, which is followed by the production of acetic acid. Vinegar is acidic because it contains acetic acid.
Thus, option C is correct.

Please Help giving high points. Perform the following mathematical operation, and eport the answer to the correct number of significant figures. 4568/1.3 = [?]
Answers
Answer:
1.3 is the value with the lowest sig figs in your question. So we have 2 sig figs.
4568/1.3 = 3513.84615
Now let's change the answer in sig figs.
We know that trailing zeros don't actually count as part of sig figs.
So we can round the answer to 3500, having the 2 sig figs (3 and 5) while the trailing zeros don't count.
Final answer = 3500

Which elements are the most reactive and why?
Answers
Answer:
Fluorine is identified as the most reactive nonmetal and the most electro-negative element in the periodic table, making it the strongest oxidizing agent. Caesium is the most reactive metal in the periodic table, so much that working with this metal often ends in explosions!
Hydrogen is a very reactive gas, and the alkali metals are even more reactive. In fact, they are the most reactive metals and, along with the elements in group 17, are the most reactive of all elements.

Answers
Answer:
D
Explanation:
Given that the molar mass of NaCl is 58.44 g/mol, we want to determine the molarity of a solution that contains 87.75 g of NaCl in 500. mL of solution.
Recall that molarity is given by:
[tex]\displaystyle \text{M} = \frac{\text{ mols solute}}{\text{ liters soln.}}[/tex]
Therefore, we can convert the amount of NaCl in the solution to moles of NaCl and the volume from milliliters to liters:
[tex]\displaystyle \begin{aligned} \text{M} & = \frac{(87.75 \text{ g NaCl})}{(500. \text{ mL soln.})} \cdot \frac{1 \text{ mol NaCl}}{58.44 \text{ g NaCl}} \cdot \frac{1000 \text{ mL soln.}}{1 \text{ L soln.}} \\ \\ & = 3.00\text{ } \frac{\text{mol NaCl}}{\text{ L soln.}} \\ \\ & = 3.00 \text{ M} \end{aligned}[/tex]
Hence, our answer is D.

Two atoms of element Q mixed with element E
Answers
Both the elements combine together due to incomplete outermost shell.
Two atoms of element Q mixed with element E in order to achieve stability because both the elements have incomplete outermost shell which make them very reactive. In element E we can see that it has 7 electrons while on the other hand, element Q has 5 number of electrons.
For gaining stability, each element has to reach 8 electrons so that's why both the elements react with each other and get stability so we can conclude that both the elements combine together due to incomplete outermost shell.

13.8 moles
Explanation:
You know that in a mole you have 6.022x10²³ something in this case of molecules. By knowing that by each mole you have 6.022x10²³ molecules, then you can establish the factor of conversion:
8.32x10²⁴molec of CO2 x 1 mol/6.022x10²³ molec of CO2
