Explanation:

Here, we want to get the number of moles of glucose in 0.5L of 0.4 M solution

Firstly, we need to recall that concentration or molarity is of the unit mol/dm^3

Mathematically, 1L is 1 dm^3 , thus, we have it that 0.4M is the same as 0.4 mol/dm^3

Now, to get the number of moles from molarity, we have to multiply the molarity by the volume

We have that as:

Lactic acidosis occurs when there is greater than 1.60 g in 4445 mL of blood

Explanation:

A normal blood lactic acid level is 0.5-1 mmol/L.

Mild to moderately elevated level of blood lactic acid known as hyperlactatemia occur when the range is between 2-4 mmol/L without metabolic acidosis.

Lactic acidosis occurs with blood lactic acid levels of > 4 mmol/L

Molar mass Lactic acid, C₃H₆O₃ = 90 g/mol

Mass 4 mmol lactic acid = 0.004 mol * 90 g/mol = 0.36 g

Mass of lactic acid in 1 litre or 1000 mL of blood = 0.36 g

Mass  of lactic acid in 4445 mL of blood = 0.36 g * (4445/1000)

Mass  of lactic acid in 4445 mL of blood = 1.60 g

Carbonic anhydrase is an important enzyme in red blood cells that catalyzes the reaction of carbon dioxide \((CO2)\) and water \((H2O)\) to form carbonic acid\((H2CO3)\).

The effect of carbonic anhydrase on the equilibrium constant, Kh, for this reaction can be described in the following steps:
1. The reaction taking place is:

\(CO2 + H2O ⇌ H2CO3\)
2. The equilibrium constant, Kh, is the ratio of the concentrations of the products to the reactants at equilibrium:

\(Kh = [H2CO3] / ([CO2] * [H2O])\)
3. Carbonic anhydrase is a catalyst, which means it speeds up the reaction without being consumed. It does this by lowering the activation energy required for the reaction to occur.
4. Although carbonic anhydrase increases the rate of the reaction, it does not affect the equilibrium constant, Kh. This is because catalysts do not change the equilibrium position of a reaction; they only speed up the time it takes to reach equilibrium.
In conclusion, carbonic anhydrase increases the rate of the reaction between \(CO2\) and \(H2O\) to form \(H2CO3\) but does not change the equilibrium constant, Kh, for the reaction.

The reaction type that characterizes the combustion of ethane is A. combination.

A combustion reaction is a type of chemical reaction in which a substance reacts with oxygen gas (O2) to produce heat and light, often in the form of a flame. Combustion reactions are exothermic, meaning they release energy in the form of heat and light.

In a combustion reaction, a fuel (such as a hydrocarbon like methane, propane, or ethane) combines with oxygen gas to produce carbon dioxide and water vapor. The general equation for a combustion reaction involving a hydrocarbon fuel is:

fuel + O2 → CO2 + H2O + heat.

In this reaction, ethane (C2H6) combines with oxygen (O2) to form carbon dioxide (CO2) and water (H2O). Therefore, the reactants (C2H6 and O2) are combining to form the products (CO2 and H2O), which is a characteristic of a combination reaction.

The concentration of H₂SO₄ solution is equal to 0.0480 M.

A neutralization reaction is described as a chemical reaction where acid and base react to produce respective salt and water. When a strong acid reacts with a strong base then the salt can be neutral.

When H₂SO₄ (a strong acid) reacts with NaOH, the resulting salt is Na₂SO₃  and water.

H₂SO₄  +  2 NaOH   →   Na₂SO₄  +   2H₂O

Given, the concentration of NaOH = 0.146 M

The volume of the NaOH = 14.85 ml = 0.01485 L

The number of moles of NaOH, n = M × V = 0.146 × 0.01485 = 0.00216 M

The volume of the  H₂SO₄ = 22.55 ml = 0.02255 L

The number of moles of  H₂SO₄, n = 0.00216/2 = 0.00108 mol

The concentration of H₂SO₄ =0.00108/0.02255 = 0.0480 M

3.21 grams of Aluminum Sulfate are got when 4 g of Aluminum Nitrate reacts chemcially with 3 g of Sodium Sulfate.

The equation given is not balanced. Thus,  when balanced the equation becomes:

2 Al(NO₃)₃ + 3 Na₂SO₄ → Al₂(SO₄)₃ + 6 NaNO₃

The molar mass of Al(NO₃)₃ is:

Al(NO₃)₃ = 1(Al) + 3(N) + 9(O) = 213 g/mol

The molar mass of Na₂SO₄ is:

Na₂SO₄ = 2(Na) + 1(S) + 4(O) = 142 g/mol

From the balanced equation, we can see that 2 moles of Al(NO₃)₃ react with 3 moles of Na2SO4 to produce 1 mole of Al₂(SO₄)₃. Therefore, we can calculate the number of moles of Al(NO₃)₃ and Na₂SO₄ that react:

Number of moles of Al(NO₃)₃ = 4 g / 213 g/mol = 0.0188 mol

Number of moles of Na₂SO₄ = 3 g / 142 g/mol = 0.0211 mol

From the balanced equation, we can see that 2 moles of Al(NO₃)₃ produce 1 mole of Al₂(SO₄)₃. Therefore, the number of moles of Al₂(SO₄)₃ produced is:

Number of moles of Al₂(SO₄)₃ = 0.0188 mol / 2 * 1 = 0.0094 mol

The molar mass of Aluminum Sulfate (Al₂(SO₄)₃) is:

Al₂(SO₄)₃ = 2(Al) + 3(S) + 12(O) = 342 g/mol

Therefore, the mass of Aluminum Sulfate produced is:

Mass of Al₂(SO₄)₃ = Number of moles of Al₂(SO₄)₃ * Molar mass of Al₂(SO₄)₃

= 0.0094 mol * 342 g/mol

= 3.21 g

Hence, 3.21 grams of Aluminum Sulfate are liberated when 4 g of Aluminum Nitrate change state with 3 g of Sodium Sulfate.

Answer:

The concentration of the nitric acid (HNO3) solution is 72 M.

Explanation:

To determine the concentration of the nitric acid solution, we can use the concept of stoichiometry and the equation of the neutralization reaction between nitric acid (HNO3) and sodium hydroxide (NaOH):

HNO3 + NaOH → NaNO3 + H2O

The balanced equation shows that the molar ratio between HNO3 and NaOH is 1:1. This means that 1 mole of HNO3 reacts with 1 mole of NaOH.

Given:

Volume of HNO3 solution = 10.0 ml

Volume of NaOH solution = 3.6 ml

Molarity of NaOH solution = 0.2 M

To find the concentration of the HNO3 solution, we need to calculate the number of moles of NaOH used in the neutralization reaction:

moles of NaOH = volume of NaOH solution * molarity of NaOH solution

= 3.6 ml * 0.2 M

= 0.72 mmol (millimoles)

Since the molar ratio between HNO3 and NaOH is 1:1, the number of moles of HNO3 in the solution is also 0.72 mmol.

Now, we can calculate the concentration of the HNO3 solution using the formula:

concentration (in M) = moles of solute / volume of solution (in L)

concentration = 0.72 mmol / 0.010 L

= 72 mmol/L

= 72 M

Therefore, the concentration of the nitric acid (HNO3) solution is 72 M.

Answer:I think its hydrogen dioxide, but I'm not sure

Explanation:

I don't know if that is correct though

The equilibrium concentrations of the gases are:

[H2] = 0.865 M, [CO2] = 0.865 M, [CO] = 1.135M ,[H2O] = 1.135 M.

The sum of the molar concentrations of the reactants (H2 and CO2) is equal to the sum of the molar concentrations of the products (CO and H2O), as expected for a reaction at equilibrium.

The equilibrium concentrations of the four gases can be determined using the equilibrium constant expression and the initial concentrations of the reactants.

The equilibrium constant expression for the reaction is:

K_eq = [CO][H2O]/[H2][CO2]

where the concentrations are in units of M (molarity).

We are given that K_eq = 0.771 at 650 degrees Celsius.

We start by setting up an ICE table (Initial, Change, Equilibrium) to determine the equilibrium concentrations:

                 H2         CO         CO  H2O

Initial 2.00 2.00 0 0

Change    -x            -x       +x     +x

Equil. 2.00-x 2.00-x x x

where "x" is the change in concentration from the initial state to the equilibrium state, and we assume that the reaction proceeds to equilibrium.

Substituting the equilibrium concentrations into the equilibrium constant expression and solving for "x", we get:

K_eq = [CO][H2O]/[H2][CO2] = x^2 / (2.00 - x)^2 = 0.771

Solving for "x" using the quadratic formula, we get:

x = 1.135 M

Therefore, the equilibrium concentrations of the gases are:

[H2] = 0.865 M

[CO2] = 0.865 M

[CO] = 1.135 M

[H2O] = 1.135 M

The equation C2H4(g) + H2(g) + C2H6(g) → Caco3(s) + Cao(s) + CO2(g) shows an increase in entropy due to the formation of a gas as a product. Option A

In this equation, the reactants on the left-hand side consist of gases (C2H4 and H2), while the products on the right-hand side include a solid (Caco3) and a gas (CO2).

When a reaction involves a change from gaseous to solid or liquid states, there is typically a decrease in entropy because the particles become more ordered and constrained in the solid or liquid phase.

Conversely, when a reaction involves the formation of gases, there is generally an increase in entropy because gases have higher degrees of molecular motion and greater freedom of movement compared to solids or liquids.

In the given equation, the reactants include three gaseous compounds (C2H4, H2, and C2H6), and one of the products is a gas (CO2). Therefore, the overall entropy of the system increases during this reaction.

The equation Fe(s) + S(s) → FeS(s) does not show an increase in entropy. Both the reactants (Fe and S) and the product (FeS) are solids. Since solids have lower entropy compared to gases or liquids, the entropy of the system does not increase in this reaction. Option A
