Explanation:

Hello there!

In this case, it is possible to comprehend these mass-particles problems by means of the concept of mole, molar mass and the Avogadro's number because one mole of any substance has 6.022x10²³ particles and have a mass equal to the molar mass.

In such a way, for C₆H₁₂O₆, whose molar mass is about 180.16 g/mol, the referred mass would be:

[tex]m=5.28x10^{19}molecules*\frac{1mol}{6.022x10^{23}molecules}*\frac{180.16g}{1mol}\\\\m=0.0158g[/tex]

Answer:

Cl₂ is the limiting reactant.

Explanation:

We'll begin by writing the balanced equation for the reaction. This is illustrated below:

N₂ + 3Cl₂ —> 2NCl₃

From the balanced equation above,

1 L of N₂ reacted with 3 L of Cl₂.

Finally, we shall determine the limiting reactant. This can be obtained as follow:

From the balanced equation above,

1 L of N₂ reacted with 3 L of Cl₂.

Therefore, 134 L of N₂ will react with = 134 × 3 = 402 L of Cl₂.

From the calculation made above, we can see that a higher volume (i.e 402 L) of Cl₂ than what was given (i.e 99 L) is needed to react completely with 134 L of N₂.

Therefore, Cl₂ is the limiting reactant and N₂ is the excess reactant.

The amount of copper in moles in the 27.5 g pure copper sheet is approximately 0.433 moles.

To calculate the amount of copper in moles in a pure copper sheet, we need to use the molar mass of copper and the given mass of the sheet.

The molar mass of copper (Cu) is approximately 63.55 g/mol. This value represents the mass of one mole of copper atoms.

Given that the mass of the pure copper sheet is 27.5 g, we can calculate the number of moles using the following formula:

moles = mass / molar mass

Substituting the values:

moles = 27.5 g / 63.55 g/mol

moles ≈ 0.433 mol

Therefore, the amount of copper in moles in the 27.5 g pure copper sheet is approximately 0.433 moles.

To arrive at this result, we divided the given mass of the sheet (27.5 g) by the molar mass of copper (63.55 g/mol). This calculation allows us to convert the mass of the sheet into the corresponding number of moles of copper.

The result tells us that the 27.5 g pure copper sheet contains approximately 0.433 moles of copper atoms. This conversion to moles is useful in various chemical calculations and allows for easier comparison and analysis of quantities on a molecular scale.

Answer:

6C2H2(g) + 16H2O(g) + 3CO2(g) ------> 6Ca(OH)2(s) +  5CH2CHCO2H(g)

Explanation:

The reaction has the first step as the reaction of calcium carbide with water to yield acetylene and calcium hydroxide as follows;

6CaC2(s) + 12H2O(g) -----> 6C2H2(g) + 6Ca(OH)2(s)

In the second step, acetylene, carbon dioxide and water react to form acrylic acid as follows;

6C2H2(g) + 4H2O(g) + 3CO2(g) ------>  5CH2CHCO2H(g)

The overall reaction equation is as follows;

6C2H2(g) + 16H2O(g) + 3CO2(g) ------> 6Ca(OH)2(s) +  5CH2CHCO2H(g)

Answer:

N2 is the limiting agent

Explanation:

We will find out if there is sufficient N2 and h2 to produce NH3

a) For 2.36 grams of N2

Molar mass of N2 = 28.02

Number of moles of N2 in 2.36 grams = 2.36/28.02

Mass of NH3 = 17.034 g

Now NH3 produced form 2.36 grams of N2 =  

2.36/28.02 * 2 * 17.034 = 2.87 g NH3

b) For 1.52 g of H2  

NH3 produced = 1.52/2.016 * (2/3) * 17.034 = 8.56

N2 Is not enough to produce 2.87 g of NH3 and also H2 is not enough to make 8.56 g of NH3.  

N2 is the limiting agent as it has smaller product mass

Answer:

420 miles

Explanation:

From the question given above, the following data were obtained:

Time = 3.5 hours

Speed = 120 mi/h

Distance =?

Speed is defined as the distance travelled per unit time. Mathematically, it is expressed as:

Speed = distance / time

With the above formula, we can obtain the distance travelled by the plane as follow:

Time = 3.5 hours

Speed = 120 mi/h

Distance =?

Speed = distance / time

120 = distance / 3.5

Cross multiply

Distance = 120 × 3.5

Distance = 420 miles

Thus, the distance travelled by the plane is 420 miles

We would need to measure out approximately 44.84 grams of C5Hg to have 0.172 mol.

To determine the grams of C5Hg needed to have 0.172 mol, we need to use the molar mass of C5Hg and the given amount in moles. The molar mass of a compound represents the mass of one mole of that compound.

The molar mass of C5Hg can be calculated by summing the atomic masses of all the atoms in the compound:

C5Hg: (5 * atomic mass of C) + (1 * atomic mass of Hg)

Using the atomic masses from the periodic table:

Atomic mass of C = 12.01 g/mol

Atomic mass of Hg = 200.59 g/mol

Molar mass of C5Hg = (5 * 12.01 g/mol) + (1 * 200.59 g/mol) = 60.05 g/mol + 200.59 g/mol = 260.64 g/mol

Now, we can calculate the grams of C5Hg needed for 0.172 mol using the mole-to-mass conversion:

Grams of C5Hg = Moles of C5Hg * Molar mass of C5Hg

Grams of C5Hg = 0.172 mol * 260.64 g/mol = 44.84 grams (rounded to two decimal places)
