Answer:

25.8 L

Explanation:

Step 1: Write the balanced equation for the complete combustion of acetylene

C₂H₂ + 2.5 O₂ ⇒ 2 CO₂ + H₂O

Step 2: Calculate the moles corresponding to 15.0 g of C₂H₂

The molar mass of C₂H₂ is 26.04 g/mol.

15.0 g × 1 mol/26.04 g = 0.576 mol

Step 3: Calculate the moles of CO₂ produced from 0.576 moles of C₂H₂

The molar ratio of C₂H₂ to CO₂ is 1:2. The moles of CO₂ produced are 2/1 × 0.576 mol = 1.15 mol.

Step 4: Calculate the volume corresponding to 1.15 moles of CO₂

At standard temperature and pressure, 1 mole of CO₂ occupies 22.4 L.

1.15 mol × 22.4 L/1 mol = 25.8 L

Answer:  16.3 L of ammonia gas can be formed from 24.5 L of hydrogen gas at STP

Explanation:

According to avogadro's law, 1 mole of every substance occupies 22.4 L at STP and contains avogadro's number [tex]6.023\times 10^{23}[/tex] of particles.

The balanced chemical equation is:

[tex]3H_2+N_2\rightarrow 2NH_3[/tex]

According to stoichiometry :

[tex]3\times 22.4=67.2L[/tex] of [tex]H_2[/tex]  produce = [tex]2\times 22.4=44.8L[/tex] of [tex]NH_3[/tex] at STP

Thus 24.5 L of [tex]H_2[/tex]  will produce= [tex]\frac{44.8}{67.2}\times 24.5=16.3L[/tex] of [tex]NH_3[/tex] at STP

Thus 16.3 L of ammonia gas can be formed from 24.5 L of hydrogen gas at STP

Answer:

When magma cools, crystals form because the solution is super-saturated with respect to some minerals. If the magma cools quickly, the crystals do not have much time to form, so they are very small. If the magma cools slowly, then the crystals have enough time to grow and become large.

Explanation:

"C" is correct.

The Law of Conservation of Mass states that matter can be neither created nor destroyed. This is evident in chemical equations as you will always start and end with the same amount of atoms of every element. They are all still there; they have just been rearranged.

Answer: C) The number of atoms of each element is the same on each side of the equation.

Explanation: Mass cannot be created nor destroyed.

Answer:

Explanation:

To find the number of moles in a substance given it's number of entities we use the formula

[tex]n = \frac{N}{L} \\[/tex]

where n is the number of moles

N is the number of entities

L is the Avogadro's constant which is

6.02 × 10²³ entities

From the question we have

[tex]n = \frac{7.72 \times {10}^{24} }{6.02 \times {10}^{23} } \\ = 12.8 239[/tex]

We have the final answer as

Answer:

M = 0.47

Explanation:

1 - Turn grams to moles using molar mass:

16g NaOH × 1 mol NaOH / 40g NaOH = 0.4 mol NaOH

2- Turn milliliters to liters:

855mL × 1 L / 1000mL = 0.86 L

3- Use formula which is M = moles of solute / liters of solvent:

M = 0.4 mol NaOH / 0.86 L = 0.47

Answer:

[tex]\boxed {\boxed {\sf B. \ 2 \ diploid \ cells \ and \ 4 \ haploid \ cells}}[/tex]

Explanation:

Mitosis is a type of cell division. It occurs in somatic cells, which are basically any cells other than sex cells. A cell replicates the genetic material then undergoes one division to create 2 identical cells, both with a complete set of chromosomes. These are known as diploid cells.

Meiosis is another type of cell division, but it occurs only in sex cells, called gametes. The cell replicates the genetic material and the chromosomes cross over, which creates completely unique cells. The cell divide to create 2 cells, but then they divide again to create 4 cells. They each have half of the chromosomes of a somatic cell, so they are haploid cells

So, mitosis results in 2 diploid cells and meiosis forms 4 haploid cells.

Answer:

48 grams

Explanation:

The chemical equation for the reaction is the following:

2 H₂ + O₂ → 2 H₂O

That means that 2 moles of H₂ react with 1 mol of O₂ to produce 2 moles of H₂O. We convert the moles of oxygen (O₂) by using the molecular weight (MW) as follows:

MW(O₂) = 16 g/mol x 2 = 32 g/mol

mass of O₂ = 1 mol x 32 g/mol = 32 g

So, we have the following stoichiometric ratio: 32 g O₂/2 moles H₂. We have 3 moles of hydrogen (H₂), so we multiply the moles by the stoichiometric ratio to calculate how many grams are needed:

3 moles H₂ x 32 g O₂/2 moles H₂ = 48 g O₂

Therefore, 48 grams of O₂ are needed to react with 3 moles of H₂.

Container 1 particles have lower average kinetic energy and higher temperature than Container 2 particles.

Explanation:

Kinetic energy is the speed of the particles in the bottle.

As you can see in the illustration below, the patricles in Picture 2 are moving faster than the ones in Picture 1.

The tempature of Container 1 is higher because all of the particles are sitting on top of one another. Not being able to move, their pressure builds up and creates heat.

Answer:

3200

Explanation:

Answer:

0.047 moles

Explanation:

From the question,

Applying

PV = nRT............. Equation 1

Where P = Pressure of CH₄ gas, V = Volume of CH₄ gas, n = number of moles of CH₄ gas, R = Molar gas constant.

make n the subject of the equation

n = PV/RT............. Equation 2

Given: P = 660 torr = (660×0.00131579) atm = 0.868 atm, V = 1300 mL = (1300/1000) L = 1.3 L, T = 20 °C = (20+273) K = 293 K

Constant: R = 0.082 atm.dm³/K.mol

Substitute these values into equation 2

n = (0.868×1.3)/(0.082×293)

n = 1.1284/24.026

n = 0.047 mole
