Complete the set-up to answer the question correctly: how many moles of NaCl can be produced from 85 g Cl2?

Answer: 0.233 M

Explanation: (0.550 M)(0.0320 L)= 17.6e-3 mol NaOH

3:1 ratio of NaOH to H3PO4 so divide the moles of NaOH (17.6e-3) by 3. You will get 5.86e-3.

Finally, divide this number (the moles of H3PO4) by the volume (0.252 L) to get 0.233 M

The concentration of given acid base reaction will be 0.226 M

The chemical reactions that take place when acids and bases are combined together are known as acid-base reactions. Acids and bases are discussed in terms of hydrogen ion exchange in the Bronsted-Lowry hypothesis. A conjugate acid as well as a conjugate base are the end products of such a reaction.

The given acid base reaction is :

H3PO4 + 3NaOH = Na3PO4 + 3H2O.

It can be seen that 3 moles of NaOH give one moles of Na3PO4.

Moles of NaOH = 0.550 M/ 0.0320 L = 17.18

So, by divide the moles of NaOH = 17.18 /3 = 5.72

The given volume = 25.2 mL = 0.252 L

Concentration of acid base reaction = n / v

where, n = moles of solute , v = liters of solution.

Now, put the value of given data in above concentration of acid base reaction formula.

Concentration of acid base reaction = 5.72 / 0.252 L = 22 .69

Therefore, the concentration of acid base reaction will be 0.226M.

There are two main types of mixtures, homogeneous mixtures and heterogeneous mixtures. The components of a homogeneous mixture are evenly distributed throughout the mixture. The properties of a mixture are the same everywhere. The components of a heterogeneous mixture are not evenly distributed. Different regions of this mixture have different   properties.

Particles in a homogeneous mixture do not settle down or separate when left alone. Particles in a heterogeneous mixture eventually separate or settle when left alone.

Answer:

59.9% is the percent yield for the 4.5 g of produced Al₂S₃

Explanation:

Let's determine the reaction:

3S  +  2Al  →  Al₂S₃

First of all, let's determine the limiting reactant. We need to convert the mass to moles:

4.8 g /32.06g/mol = 0.150 moles of S

5.4 g / 26.98 g/mol = 0.200 moles of Al

3 moles of S react to 2 moles of Al

Then, 0.150 moles of S may react to (0.150 . 2)/3 = 0.1 ,moles of Al

We have 0.200 moles and we only have 0.1. As we have excess of Al, this is the excess reactant. In conclussion, the limiting reagent is S.

2 moles of Al react to 3 moles of S

Then 0.2 moles of Al may react to (0.2 . 3) /2 = 0.3 moles of S. (We only have 0.150 moles)

Let's go to the product, 3 moles of S can produce 1 mol of Al₂S₃

Then 0.150 moles of S, may produce (0.150 . 1) /3 = 0.05 moles.

We convert moles to mass to determine the thoretical yield:

0.05 mol . 150.15g /mol =  7.50g

Percent yield = (Produced yield/Theoretical yield) . 100

% = (4.5g / 7.5g) . 100 = 59.9%

Explanation:

Q = 373J

∆∅ = 25°C

m = 312g

c = x

Q = mc∆∅

373 = 312(x)(25)

373 = 7800x

x = 373/7800

x = 0.0478J/(g°C)

The specific heat of the substance if 373 J is required to raise teh temperature of a 312 gram sample by 25°C is 0.0478 J/g

The amount of energy needed to raise the temperature of one gram of a substance by one degree Celsius.

By the formula of specific heat

Q = mc∆∅

Q = 373J

m = 312g

∆∅ = 25° C

Putting the values in the equation

[tex]373 = 312\times c \times (25)\\\\373 = 7800c\\c= \dfrac{373}{7800} = 0.0478J/(g \circ C)[/tex]

Thus, the specific heat of the substance if 373 J is required to raise teh temperature of a 312 gram sample by 25°C is 0.0478 J/g

decomposition reaction

Answer: Na2C2O4 probably sodium oxalate

Explanation: assume you have 100 g substance.

Mass of Na is m(Na) = 34.31 g, m(C) = 17.93 g and m(O) = 47.76 g.

Calculate moles n(Na) = 34.31 g/22.99 g/mol= 1.49 mol.

For C n(C) = 1.49 mol and n(O) = 2.985. You divide all by 1.49 you

Get n(Na) : n(C) : n(O) = 1:1:2 M(NaCO2) = 67 g/mol.

Divide 134:67 = 2. You get formula Na2C2O4

Answer:

[KBr] = 454.5 m

Explanation:

m is a sort of concentration that indicates the moles of solute which are contianed in 1kg of solvent.

In this case, the moles of solute are 0.25 moles.

Let's determine the mass of solvent in kg.

Density of heavy water, solvent, is 1.1 g/L and our volume is 0.5L.

1.1 g = mass of solvent / 0.5L, according to density.

mass of solvent = 0.5L . 1.1g/L = 0.55 g

We convert the mass to kg → 0.55 g . 1kg /1000g = 5.5×10⁻⁴ kg

m = mol/kg → 0.25 mol /5.5×10⁻⁴ kg = 454.5 m

3-methylhexane is the molecule that is a branched alkane. Therefore, the correct option is option C.

Alkanes, often known as paraffin, are acyclic saturated hydrocarbons in organic science. In other terms, an alkane is made up of carbon and hydrogen atoms that organise themselves in a tree-like arrangement with only single carbon-carbon bonds. Alkanes have the chemical formula CnH2n+2 in general.

Methanogenic bacteria generate methane, and certain long-chain alkanes have pheromone-like properties in some animal species or serve as safeguarding waxes in some plants and fungus. However, the majority of alkanes have little biological action. 3-methylhexane is the molecule that is a branched alkane.

Therefore, the correct option is option C.
