What impact would adding twice as much na2co3 than required for stoichiometric quantities have on the quantity of product produced?

Answers

Answer 1

The product will not be affected by the addition of twice as much Na₂CO₃.

What is Limiting reagent in stoichiometry ?The maximum quantity of the end product determined by a balanced chemical equation is known as the Stoichiometry.The limiting reactant is the one that is consumed first and sets a limit on the quantity of product(s) that can be produced, and the one which remains unconsumed after the final reaction is in Excess.Calculate the moles of each reactant present and contrast it with the mole ratio of the reactants in the balanced equation to determine which reactant is the limiting one.

Here,taking the stoichiometry into consideration, we find that the reaction happens with 1:1 ratio; so, adding twice the amount of Na₂CO₃ will  lead to its excess making the other the limiting reactant, hence, it would not affect the yield of the product.

Answers

The rate of reaction of the value of KIS 3 and [A] and [B] are each 2M is: 24 (mol/L)/s (Option B)

What is rate of reaction?

In chemistry, the rate of reaction describes how quickly a chemical reaction develops.

It is frequently described in terms of either the concentration of a reactant that is spent in a unit of time or the concentration of a product that is generated in a unit of time (amount per unit volume).

What is the calculation that supports that above answer?

Recall that the rate equation is:
Rate = K[A]²[B]

Hence:

Concentration of A = 2M

Concentration of B = 2M

K = 3

Taking the values and substituting them, we have:

Rate = 3 (mol/L)⁻³/s×[2]² ×[2]

Rate = 24 (mol/L)⁻³/s

What is the usefulness of Rate of Reaction?

The rate of reaction can be used as a valuable diagnostic tool. We may devise strategies to increase production by learning how quickly things are created and what slows down reactions.

This knowledge is necessary for the industrial production of various chemicals, such as:

Answer:

Explanation:

(empirical formula)n=molar mass

Answer: C_6 H_12 O_6

Explanation: The molar mass of glucose is given as 180.16 gm/mol.

It is 40% carbon, so the weight of the carbon is 40% of 180.16 =72.06 gm. The molar weight of the carbon is 12.011 gm, so the total number of the moles of carbon are 72.06/12.011 = 6 moles.

It is 6.719% of hydrogen, so the weight of the hydrogen is 6.719% of 180.16 = 12.105 gm. The molar weight of the hydrogen is 1.008 gm, so the total number of the moles of hydrogen are 12.105/1.008 = 12 moles.

It is 53.27% of oxygen, so the weight of the oxygen is 53.27% of 180.16 = 95.97 gm. The molar weight of the oxygen is 16 gm, so the total number of the moles of oxygen are 95.97/16 = 6 moles.

Answers

Taking into account the definition of calorimetry, the specific heat of the metal is 0.14 [tex]\frac{J}{gC}[/tex].

Calorimetry

Calorimetry is the measurement and calculation of the amounts of heat exchanged by a body or a system.

Sensible heat is defined as the amount of heat that a body absorbs or releases without any changes in its physical state (phase change).

So, the equation that allows to calculate heat exchanges is:

Q = c× m× ΔT

where:

Q is the heat exchanged by a body of mass m.

c is specific heat substance.

ΔT is the temperature variation.

In this way, between heat and temperature there is a direct proportional relationship (Two magnitudes are directly proportional when there is a constant so that when one of the magnitudes increases, the other also decreases; and the same happens when either of the two decreases .).

The constant of proportionality depends on the substance that constitutes the body and its mass, and is the product of the specific heat by the mass of the body.

Specific heat of the metal

In this case, you know:

Q= 175 Jm= 50 gc= ?ΔT= Tfinal - Tinitial= 50 C - 25 C= 25 C

Replacing in the expression to calculate heat exchanges:

175 J= c× 50× 25 C

Solving:

c=[tex]\frac{175 J}{50 gx25C}[/tex]

c=0.14 [tex]\frac{J}{gC}[/tex]

Finally, the specific heat of the metal is 0.14 [tex]\frac{J}{gC}[/tex].

What is the molar mass of a protein if a 0. 30 l of solution containing 0. 45 g of the protein has an osmotic pressure of 0. 80 torr at 25∘c?

Answers

The molar mass of a protein if a 0. 30 l of solution containing 0. 45 g of the protein has an osmotic pressure of 0. 80 torr at 25∘c is 0.348 g/mol

Here we can apply the formula ∏ = iMRT, where ∏ = osmotic pressure = 0.80 - ( given ). This is only one part of the information we are given / can conclude in this case ....

i = van’t Hoff factor = 1 for a protein molecule,

R = gas constant = 62.36 L torr / K-mol,

T ( temperature in Kelvin ) = 25 + 273 - conversion factor C° + 273 = 298K

( Known initially ) ∏ = osmotic pressure = 0.80 torr

besides the part " M " in the formula, which we have no information on whatsoever, as we have to determine it's value.

_____

Substitute derived / known values to solve for M ( moles / liter ) -

∏ = iMRT

⇒ 0.80 = ( 1 )( M )( 62.36 )( 298 )

⇒ 0.80 = M( 18583.28 )

⇒ M = 0.80 / 18583.28 ≈ 4.3049 ....

_____

We know that M = moles / liter, so we can use this to solve for moles, and hence calculate the molar mass by the formula molar mass = g / mol -

M = mol / l

⇒ 4.3049 = 0.045 / 25 mL ( 0.030 L ),

0.045 / 0.030 = 1.5 g / L

⇒ 1.5 g = 4.3049 moles,

molar mass = 1.5 g = 4.3049 moles = 0.348 g / mol

Sand and pepper are insoluble; even hot water won't make them dissolve.There are three ways that substances can dissolve in water: dissociation, dispersion, and ionization.

Types of dissolved substances that may be present in water​:

Ionic chemicals and polar molecular compounds, for example, will dissolve in water since it is a polar molecules.

When it comes to organic compounds, water will dissolve any that have a carbon to oxygen atom ratio of less than or equal to 5.

Why do you add hydroxide to your hexanediamine solution? what would occur if you did not add it?.

Answers

Why is Hydroxide added ?

In the polymerization reaction, the lone pair electrons on the NH₂ groups of hexanediamine attack the C=O groups of the dicarboxylic acid in a nucleophilic substitution reaction as shown in the image.

Hydroxide is added to remove any H⁺ ions present and keep the hexanediamine in the deprotonated form, so that the NH₂ lone pair electrons are available for reaction.

What if you don't add it ?

If hydroxide is not added, the NH₂ groups will get protonated by H⁺  ions present to give NH₃⁺ groups, which cannot react.

Which substance is a product of glycolysis, a precursor of gluconeogenesis and a precursor of the citric acid cycle?

Answers

Pyruvate substance is a product of glycolysis, a precursor of gluconeogenesis and a precursor of the citric acid cycle

A crucial node in the network of metabolic pathways is pyruvate. Pyruvate can be transformed into ethanol, the amino acid alanine, fatty acids or energy through acetyl-CoA, carbohydrates through gluconeogenesis, and fatty acids or energy. As a result, it combines numerous important metabolic activities.

Pyruvate's main job is to carry carbon atoms into the mitochondrion where they are fully oxidized into carbon dioxide.

The final byproduct of glycolysis, pyruvate, is crucial to cell metabolism. It is made in the cytosol and then oxidized in the mitochondria, where it activates oxidative phosphorylation and feeds the citric acid cycle.
