2.00 L of 0.800 M NaNO3 must be prepared from a solution known to be 2.50 M in concentration.How many mL are required? Plus don't send me virus links!!!! pls explain how to do it
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.

A. carbon
B. fluorine
C. nitrogen
D. oxygen
a. Two possible Lewis electron-dot diagrams for CO2 are shown above. Explain in terms of formal charges why diagram Z is the better diagram.
b. Identify the hybridization of the valence orbitals of the C atom in the CO2 molecule represented in diagram Z.
The carbon atom is SP hybridized while the oxygen atom is SP2 hybrized.
What are resonance structures?The term resonance structures are those structures that can be used to explain the bonding in a molecule. Sometimes, a single structure is insufficient in explaining the structure of a compound.
Now looking at the two sturctures, Z is better because there are mo formal charges which make the molecle less stable unlike in X. In the CO2 molecule, the carbon atom is SP hybridized while the oxygen atom is SP2 hybrized.

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?
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.
A balloon that can hold 85 L of air is inflated with 3.5 moles of gas at a pressure of 1.0 atmosphere. What is the temperature of the balloon?
Answer:

5
Answer:
# 5
Explanation:
The question describes silver being "poured" into a mold and cools to become a solid bar. This is the phase of liquid to solid. When a element cools down below it's freezing points to become a solid.
Liquid to Solid Definition:
Freezing, or solidification, is a phase transition in which a liquid turns into a solid when its temperature is lowered to or below its freezing point. All known liquids, except helium, freeze when the temperature is low enough.

A sample of 10.5g of Nirtogen reacts with 20.2g of Hydrogen to produce ammonia.
3H2(g)+N2(g)=2NH3(g)
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?
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.
e) (actual)/(theoretical) * 100 = (4.1)/(30.7) * 100 = 13%
