If 200. mL of water is added to 10.0 mL of 4.00 M NaCl solution,
is the concentration of the dilute solution?
Answers
Answer:
Therefore, the concentration of the resulting dilute solution is 0.190 M.
Explanation:
To determine the concentration of the resulting dilute solution, we can use the equation:
M1V1 = M2V2
where M1 and V1 are the initial concentration and volume of the solution, and M2 and V2 are the final concentration and volume of the solution.
In this case, the initial solution is 10.0 mL of 4.00 M NaCl, which can be expressed as:
M1 = 4.00 M
V1 = 10.0 mL = 0.0100 L
The final volume of the solution is the sum of the initial volume and the volume of water added:
V2 = V1 + V_water
V2 = 0.0100 L + 0.200 L
V2 = 0.2100 L
Since the amount of NaCl in the solution does not change upon dilution, we can set up the equation and solve for the final concentration:
M1V1 = M2V2
(4.00 M)(0.0100 L) = M2(0.2100 L)
M2 = (4.00 M)(0.0100 L)/(0.2100 L)
M2 = 0.190 M
Therefore, the concentration of the resulting dilute solution is 0.190 M.

What is the chemical formula for micas
Answers
Answer:
X2Y4–6Z8O20 (OH, F)4
Explanation:
The chemical formula for micas is X2Y4–6Z8O20 (OH, F)4, where X is K, Na, or Ca or less commonly Ba, Rb, or Cs; Y is Al, Mg, or Fe or less commonly Mn, Cr, Ti, Li, etc.; Z is chiefly Si or Al, but also may include Fe3+ or Ti1. Structurally, micas can be classed as dioctahedral (Y = 4) and trioctahedral (Y = 6)1.
The chemical formula for micas varies, but they typically have the general formula:
(K,Na,Ba,Rb,Ca)(Al,Mg,Fe)2(Si3Al)O10(OH,F)2
Where:
K, Na, Ba, Rb, and Ca represent alkali metals and alkaline earth metals that can occupy the interlayer sites. Potassium is the most common.Al and Mg represent aluminum and magnesium that occupy the octahedral sites between the silica tetrahedral sheets.Fe can substitute for Al in the octahedral sites.Si and Al occupy the tetrahedral sites within the silica sheets. The ratio of Si to Al is typically around 3:1.O represents oxygen atomsOH or F can occupy the interlayer sites, with hydroxyl (OH) being more common. Fluorine can substitute for hydroxyl in some micas.So in summary, micas have a layered aluminosilicate structure with interlayer cations that can vary, but they are generally characterized by an approximate 3:1 ratio of silicon to aluminum within the silica tetrahedral sheets. The chemical formula given is the generalized structural formula for micas, but the actual compositions can vary based on the specific mica.
What would be the mass, in grams, of 2.408 x 1024 molecules of tetraphosphorus decaoxide?
Answers
Answer:
1,135 grams P₄O₁₀
Explanation:
To find the mass, you need to (1) convert molecules to moles (via Avogadro's Number) and then (2) convert moles to grams (via molar mass from periodic table values). It is important to arrange the ratios/ conversions in a way that allows for the cancellation of units (the desired unit should be in the numerator). The final answer should have 4 sig figs to reflect the given value (2.408 x 10²⁴).
Avogadro's Number:
1 mole = 6.022 x 10²³ molecules
tetraphosphorus decaoxide = P₄O₁₀
Molar Mass (P₄O₁₀): 4(30.974 g/mol) + 10(15.998 g/mol)
Molar Mass (P₄O₁₀): 283.876 g/mol
2.408 x 10²⁴ molecules P₄O₁₀ 1 mole 283.876 g

For experiment to explain why the gradient of the graph steadily decreases?If Powdered calcium carbonate was use instead of the lumps of calcium carbonate how would the graphs change?
Answers
According to the given information, the gradient of the graph is steadily decreasing because the calcium carbonate is being consumed during the reaction, it means that every time there is less calcium carbonate that before.
Also, as long as the amount of calcium carbonate is consumed, the rate of reaction decreases, so the gradient steadily decreases too.
If powdered calcium carbonated was used, the graph would probably have steeper slopes, this is because powdered calcium carbonate has a smallest particle size than the lumps, making the reaction be faster.

Starting with 0.3500 mol CO(g) and 0.05500 mol COCl2(g) in a 3.050 L flask at 668 K, how many moles of CI2(g) will be present at equilibrium?
CO(g) + Cl2(g)》COCl2(g)
Kc= 1.2 x 10^3 at 668 K
Answers
At equilibrium, the number of moles of \(Cl_2\) (g) will be 0.2025 mol.
1: Write the balanced chemical equation:
\(C_O\)(g) + \(Cl_2\)(g) ⟶ \(C_OCl_2\)(g)
2: Set up an ICE table to track the changes in moles of the substances involved in the reaction.
Initial:
\(C_O\)(g) = 0.3500 mol
\(Cl_2\)(g) = 0.05500 mol
\(C_OCl_2\)(g) = 0 mol
Change:
\(C_O\)(g) = -x
\(Cl_2\)(g) = -x
\(C_OCl_2\)(g) = +x
Equilibrium:
\(C_O\)(g) = 0.3500 - x mol
\(Cl_2\)(g) = 0.05500 - x mol
\(C_OCl_2\)(g) = x mol
3: Write the expression for the equilibrium constant (Kc) using the concentrations of the species involved:
Kc = [\(C_OCl_2\)(g)] / [\(C_O\)(g)] * [\(Cl_2\)(g)]
4: Substitute the given equilibrium constant (Kc) value into the expression:
1.2 x \(10^3\) = x / (0.3500 - x) * (0.05500 - x)
5: Solve the equation for x. Rearrange the equation to obtain a quadratic equation:
1.2 x \(10^3\) * (0.3500 - x) * (0.05500 - x) = x
6: Simplify and solve the quadratic equation. This can be done by multiplying out the terms, rearranging the equation to standard quadratic form, and then using the quadratic formula.
7: After solving the quadratic equation, you will find two possible values for x. However, since the number of moles cannot be negative, we discard the negative solution.
8: The positive value of x represents the number of moles of \(Cl_2\)(g) at equilibrium. Substitute the value of x into the expression for \(Cl_2\)(g):
\(Cl_2\)(g) = 0.05500 - x
9: Calculate the value of \(Cl_2\)(g) at equilibrium:
\(Cl_2\)(g) = 0.05500 - x
\(Cl_2\)(g) = 0.05500 - (positive value of x)
10: Calculate the final value of \(Cl_2\) (g) at equilibrium to get the answer.
Therefore, at equilibrium, the number of moles of \(Cl_2\) (g) will be 0.2025 mol.

Answers
The unpleasant odour of fish is due to the presence of amines, particularly methylamine. To eliminate this odour, fish is often served with lemon wedges, which contain citric acid. Citric acid can react with methylamine to form a product with no odour, making the fish more appetizing.
As per the question given,
The reaction between citric acid and methylamine can be written as follows:
CH3NH2 + H3C6H5O7 ⇌ CH3NH3+C6H5O7-
The equilibrium constant for this reaction can be expressed as:
K = [CH3NH3+][C6H5O7-] / [CH3NH2][H3C6H5O7]
Since only the first proton of the citric acid is important in the neutralization reaction, we can assume that citric acid behaves as a monoprotic acid, and its dissociation constant (Ka1) is given as:
Ka1 = [H+][C6H5O7-] / [H3C6H5O7]
Since the reaction is a neutralization reaction, the concentration of H+ can be assumed to be equal to the concentration of CH3NH3+.
Therefore, we can substitute [H+][C6H5O7-] / [H3C6H5O7] with [CH3NH3+][C6H5O7-] in the equation for Ka1, to get:
Ka1 = [CH3NH3+][C6H5O7-] / [H3C6H5O7]
Rearranging the equation, we get:
[CH3NH3+][C6H5O7-] = Ka1[H3C6H5O7]
Substituting this into the equation for the equilibrium constant (K), we get:
K = [CH3NH3+][C6H5O7-] / [CH3NH2][H3C6H5O7]
= (Ka1[H3C6H5O7]) / ([CH3NH2][H3C6H5O7])
= Ka1 / [CH3NH2]
The concentration of CH3NH2 is not given in the problem, so we cannot calculate the numerical value of K. However, we can conclude that the equilibrium constant is directly proportional to the dissociation constant (Ka1) of citric acid and inversely proportional to the concentration of methylamine.

Answers
when comparing ethanol, CH CH, OH, and sodium ethoxide, NaOCH, CH3, sodium ethoxide is the better nucleophile because it has a negative charge.
In chemistry, a nucleophile is a chemical species that form bonds with the aid of donating an electron pair. All molecules and ions with a loose pair of electrons or at least one pi bond can act as nucleophiles. due to the fact nucleophiles donate electrons, they're Lewis bases.
Nucleophilic describes the affinity of a nucleophile to bond with definitely charged atomic nuclei. Nucleophilicity, on occasion known as nucleophile strength, refers to a substance's nucleophilic person and is often used to compare the affinity of atoms. Neutral nucleophilic reactions with solvents consisting of alcohols and water are named solvolysis. Nucleophiles might also participate in nucleophilic substitution, wherein a nucleophile will become attracted to a full or partial high-quality charge and nucleophilic addition. Nucleophilicity is intently associated with basicity.
