When 20.00 mL of an unknown monoprotic acid is titrated with 0.125 M NaOH, it takes 15.00 mL to reach the endpoint. What is the molarity of the unknown acid?
Answers
Answer:
About 0.0940 M.
Explanation:
Recall that NaOH is a strong base, so it dissociates completely into Na⁺ and OH⁻ ions. Because the acid is monoprotic, we can represent it with HA. Thus, the reaction between HA and NaOH is:
[tex]\displaystyle \text{HA}_\text{(aq)} + \text{OH}^-_\text{(aq)} \longrightarrow \text{H$_2$O}_\text{($\ell$)} + \text{A}^-_\text{(aq)}[/tex]
Using the fact that it took 15.00 mL of NaOH to reach the endpoint, determine the number of HA that was reacted with:
[tex]\displaystyle \begin{aligned} 15.00\text{ mL} &\cdot \frac{0.125\text{ mol NaOH}}{1\text{ L}} \cdot \frac{1\text{ L}}{1000\text{ mL}} \\ \\ &\cdot \frac{1\text{ mol OH}^-}{1\text{ mol NaOH}} \cdot \frac{1\text{ mol HA}}{1\text{ mol OH}^-}\\ \\ & = 0.00188\text{ mol HA}\end{aligned}[/tex]
Therefore, the molarity of the original solution was:
[tex]\displaystyle \left[ \text{HA}\right] = \frac{0.00188\text{ mol}}{20.00\text{ mL}} \cdot \frac{1000\text{ mL}}{1\text{ L}} = 0.0940\text{ M}[/tex]
In conclusion, the molarity of the unknown acid is about 0.0940 M.
2C₂H₂(g) + 5O₂(g) —> 4CO₂(g) +2H₂O(g)
b. How many moles of H₂O are produced when 64.0g C₂H₂ burns in oxygen?
Answers
64.0g C2H2 X 1 mol C2H2 over 26.04g C2H2 X 2 mol H2O over 2 mol C2H2
The first step of the equation is a basic diversion factor showing that for ever C2H2, there’s one mole. I got the number 26.04 grams of C2H2 by calculating their combined mass. To do that, I added them from the periodic table for and multiplied it by the amount of each that I had. Which was displayed as 12.01(2) + 1.01(2)
The second step to the equation is the mole conversion factor. In this step, I took the number of moles from the equation. That just shows that for every 2 moles of C2H2, there will be 2 moles of H2O.
After setting it up, you can ignore any ones in the problem as they won’t make any difference in the answer. And since, in this equation, the moles in the mole conversion factor are equal, you may ignore those too as they will divide down to one and not have any significance.
Now, to find the answer I divided 64.0g C2H2 by 26.04g C2H2 since everything else cancelled out. It equals 2.457757296 moles of H20. But, to get get credit for the sig-figs, you’ll have to change the numbers before submitting.
The beginning number has three placements (64.0) so the answer must also have three. If we look at the long decimal we got in the calculator, we can go over three and round the last number either up or down depending on the fourth number.
A sample of 10.5g of Nirtogen reacts with 20.2g of Hydrogen to produce ammonia.

a. What is the theoretical yield of ammonia?
b. What is the limiting reactant?
c. What is the excess reactant?
d. How much is the excess reactant?
e. If 4.1 g of ammonia is actually produced, what is the precent yield?
Answers
Answer:
Explanation:
a) The mass of the reactants is 10.5 + 20.2 = 30.7, so the theoretical yield of ammonia is also 30.7 grams (by the law of conservation of mass)
b) The gram-formula mass of diatomic nitrogen is about 28.014 g/mol, so 10.5 grams of nitrogen is 10.5/28.014 = 0.37 moles. In comparison, the gram-formula mass of diatomic hydrogen is about 2.016 g/mol, so 20.2 grams of hydrogen is about 20.2/2.016 = 10.0 moles. Dividing this by 3, we get 3.33 moles. So, nitrogen is the limiting reactant.
c) Hydrogen
d) 0.37 moles of nitrogen is consumed, so (0.37)(3) = 1.11 moles of hydrogen is consumed. This means that 3.33-1.11=2.22 moles of hydrogen are remaining, which has a mass of (2.22)(2.016)=4.47 grams.

name the covalent compound:
I8P
Answers
There are certain rules to follow when naming covalent compounds. But first, let us look at the definition of Covalent Compounds.
What are Covalent Compounds?
When covalent bonds aid the creation of a molecule, in which the atoms have at least one similar pair of valence electrons, a covalent compound is said to have been formed.
A very common example is water (H₂O)
How are Covalent Compounds named?
To name a covalent compound, simply list the first element in the formula using the name of the element, then name the second element by adding the suffix "ide" to the stem of the second element's name.
If there is only one atom in the molecule of the first element, then no prefix should be added.
It is to be noted that if the second element in the compound is oxygen, then we should say:
monoxide instead of monooxide andtrioxide instead of troxide, all depending on how many atoms that are involved.See the attached for the prefixes related to the various number of atoms in the compounds.
It is to be noted that the covalent compound to be named here is not stated hence the general answer.

An aqueous solution has 124 g of a salt dissolved in 1000 g of solution. What is the concentration of the salt in units of %?
Answers
Answer: 12.4%
Explanation:
124/1000 * 100 = 12.4%
According to the concept of percent solution,the concentration of salt in percent units is 12.4 %.
What is percent solution?Percent solution is defined as a convenient way to record concentration of solution.It is a expression which relates solute to solvent as,mass of solute/mass of solution ×100.There are two types of percentage solutions percent weight by volume and percent volume by volume .Advantages of using percent solutions is that molecular weight of compound is not required.
Percent solutions are of important use in industries and laboratories for measuring concentration of solutions.
In the given example, percent concentration is found out as, mass of solute/ mass of solution ×100 thus substitution of values gives 124/1000×100=12.4%.
Thus, the percent concentration is 12.4%.

Answers
Answer:
1.36 × 10³ mL of water.
Explanation:
We can utilize the dilution equation. Recall that:
[tex]\displaystyle M_1V_1= M_2V_2[/tex]
Where M represents molarity and V represents volume.
Let the initial concentration and unknown volume be M₁ and V₁, respectively. Let the final concentration and required volume be M₂ and V₂, respectively. Solve for V₁:
[tex]\displaystyle \begin{aligned} (2.50\text{ M})V_1 &= (0.800\text{ M})(2.00\text{ L}) \\ \\ V_1 & = 0.640\text{ L} \end{aligned}[/tex]
Therefore, we can begin with 0.640 L of the 2.50 M solution and add enough distilled water to dilute the solution to 2.00 L. The required amount of water is thus:
[tex]\displaystyle 2.00\text{ L} - 0.640\text{ L} = 1.36\text{ L}[/tex]
Convert this value to mL:
[tex]\displaystyle 1.36\text{ L} \cdot \frac{1000\text{ mL}}{1\text{ L}} = 1.36\times 10^3\text{ mL}[/tex]
Therefore, about 1.36 × 10³ mL of water need to be added to the 2.50 M solution.
