Which set of coefficients will balance this chemical equation?
C2H4(g) + _O2(g) → 2C02(g) + 2H2O(g)

Answer:

Both are made up of two substances that are not chemically combined.

Explanation:

Solutions can be classified as a mixture because both are made up of two substances that are not chemically combined.

A mixture is made up of the following properties:

Solutions share this property with all mixtures.

Answer:

Percent yield = 86.09%

Theoretical yield of AgCl = 44.72 g

Explanation:

Given data:

Mass of silver(1) nitrate = 53.0 g

Actual yield of AgCl = 38.5 g

Theoretical yield of AgCl = ?

Percent yield = ?

Solution:

Chemical equation:

AgNO₃ + KCl    →   AgCl + KNO₃

Number of moles of AgNO₃:

Number of moles = mass/molar mass

Number of moles = 53.0 g/ 169.87 g/mol

Number of moles = 0.312 mol

now we will compare the moles of AgNO₃ and AgCl

               AgNO₃         :           AgCl

                   1               :                1

                0.312          :           0.312

Theoretical yield of AgCl:

Mass = number of moles × molar mass

Mass = 0.312 mol × 143.32 g/mol

Mass = 44.72 g

Percent yield:

Percent yield = (actual yield / theoretical yield) × 100

Percent yield = ( 38.5 g / 44.72 g ) × 100

Percent yield = 86.09%

Answer: C7H14 - PubChem.

Explanation:

Answer:

oxygen

Explanation:

Answer:

Water has polar O-H bonds. The negative O atoms attract the positive H atoms in nearby molecules, leading to the unusually strong type of dipole-dipole force called a hydrogen bond. Since water has hydrogen bonds, it also has dipole-induced dipole and London dispersion forces.

Answer:

0.474 moles of C₆H₆OS

Explanation:

Step 1: Write the balanced equation

2 C₆H₆OS + 11 O₂ ⇒ 12 CO + 6 H₂O + 2 SO₃

Step 2: Establish the appropriate molar ratio

According to the balanced equation, the molar ratio of C₆H₆OS to SO₃ is 2:2.

Step 3: Calculate the moles of C₆H₆OS reacted if 0.474 moles of SO₃ are produced

We will use the previously established molar ratio.

0.474 mol SO₃ × 2 mol C₆H₆OS/2 mol SO₃ = 0.474 mol C₆H₆OS

Answer:

All electric heaters make use of one or more of the fundamental heat transfer mechanisms – namely convection, conduction, or radiation.

For regular...

Conduction is heat transfer by direct contact, like frying an egg. Convection is heat transfer by the movement of gases or liquids, like most home furnaces, clothes dryers, or car heaters. Radiation is the transfer of heat in waves through space, like the sun or a fire.

Explanation:

neutalize acidity level

Materials are transferred between individual cells and their internal environment through the cell membrane by diffusion, osmosis, and active transport. During diffusion and osmosis, molecules move from a higher concentration to a lower concentration. Osmosis: Osmosis is the movement of solvent particles across a semipermeable membrane from a dilute solution into a concentrated solution. Diffusion: Diffusion is the movement of particles from an area of higher concentration to lower concentration. This would be the diffusion.

The chemical formula : 3HgBr₂(Mercury(II) bromide)

Given

The chemical formulas of Mercury and Bromine

Required

The appropriate chemical formula

Solution

A molecular formula is a formula that shows the number of atomic elements that make up a compound.  

The number of molecules is determined by the coefficient in front of the compound

the number of atoms is determined by the subscript after the atom and the coefficient

Three molecules⇒ coefficient = 3

one atom of Mercury ⇒Hg

two atoms of Bromine ⇒ Br₂

The chemical formula : 3HgBr₂

Answer:

D) The presence of additional Br- ions already in the solution means equilibrium will be reached when much less CuBr has dissolved.

Explanation:

CuBr ⇄ [tex]Cu^+[/tex] + [tex]Br^-[/tex]

Because there is Br- in CuBr, when put into solution, those Br- ions become part of the products side of the equation, shifting the equilibrium back towards the CuBr side, meaning less CuBr will dissolve.

The decrease in the solubility of the CuBr in NaBr solution has been due to the presence of additional Br ions in the solution. Thus option C is correct.

The equilibrium position has been the condition when the concentration of the reactants and products has been equal. The solubility of the CuBr has been dependent on the ksp for the solution.

The ksp has been the solubility product and has been dependent on the concentration of the reactants. The NaBr solution will be dissociated in the form of Na ions and Br ions. The dissolution has been based on the equilibrium of the CuBr.

With the presence of additional Br ions, the equilibrium of the CuBr solution has been reached earlier, and thereby the solubility of the solution has been decreased.

The decrease in the solubility of the CuBr in NaBr solution has been due to the presence of additional Br ions in the solution. Thus option C is correct.

Answer:

2.85moles of oxygen gas

Explanation:

Given parameters:

Volume of oxygen gas  = 63.8L

Unknown:

Number of moles  = ?

Solution:

We assume that the gas is under standard temperature and pressure. To find the number of moles, use the expression below:

     1 mole of a gas at STP occupies a volume of 22.4L

 So;

       63.8L of oxygen gas will take up a volume of

              [tex]\frac{63.8}{22.4}[/tex]   = 2.85moles of oxygen gas
