Answer:

Answer: C

Melamine resin or melamine formaldehyde (also shortened to melamine) is a resin with melamine rings terminated with multiple hydroxyl groups derived from formaldehyde. This thermosetting plastic material is made from melamine and formaldehyde.

Melamine formaldehyde is a thermosetting plastic (or thermoset) that strengthens as it is heated during its preparation.

The extra conversion of concentration of reactant and product should be zero in order to attaining equlibrium state.

Chemical equilibrium refers to the state in which both the reactants and products are present in equal concentrations or amount. In equlibrium, same amount of reactant is converted into product and product into reactant.

So we can conclude that the extra conversion of concentration of reactant and product should be zero in order to attaining equlibrium state.

The intermolecular forces present in B will be much stronger than the intermolecular forces present in A.

The term intermolecular forces has to do with the forces that hold molecules of a substance together in a particular state of matter. Now, we can see that B must contain dipole - dipole interaction while A has none of these.

It then follows that the intermolecular forces present in B will be much stronger than the intermolecular forces present in A.

The actual reaction to make water is a bit more complicated: 2H2 + O2 = 2H2O + Energy. In English, the equation says: To produce two molecules of water (H2O), two molecules of diatomic hydrogen (H2) must be combined with one molecule of diatomic oxygen (O2). Energy will be released in the process.

I recently answered this question. The response I submitted is included below. I beleive my answer should be correct.

Explanation:

Question 1:

C: 48.38g(1mol/12g) = 4.0317 

H: 8.12g(1mol/1.01g) = 8.12

O: 53.5g(1mol/16g) = 3.34375

Divide by the smallest amount (3.34375)

C = 4.0317/3.34375 = 1.206 = 1

H = 8.12/3.34375 = 2.42 = 2

O = 3.34375/3.34375 = 1

Empirical formula = CH2O

Question 2:

Molecular formula = n(empirical formula)

n = molar mass (compound)/molar mass (empirical)

Empirical formula: CH2O

Molar mass of CH2O = 12 + 2x1 + 16 = 30 g/mol

Molar mass of compound: 180.15 g/mol

[tex]n = \frac{180.15g/mol}{30g/mol} = 6[/tex]

Molecular formula = C6H12O6

my teacher hasnt graded yet, but i got the same answer as the guy above. i did my best to explain the process for y'all if you genuinely don't understand/know how to do it. THE PROCESS IS VERY LONG, but youll get it eventually if i didnt help lol GOODLUCK

and yes, the molecular formula is C6H12O6

Activation energy will be less than the energy of the products in an exothermic reaction. Therefore, option (D) is correct.

In this type of reaction, the energy of the products is lower than the energy of the reactants. As a result, the difference in energy is released as heat or light, which can be detected by measuring the temperature or observing the light emitted during the reaction.

Exothermic reactions occur spontaneously, meaning they do not require an external energy source to start the reaction. Common examples of exothermic reactions include combustion, oxidation, and neutralization. These reactions often involve the formation of stronger bonds between atoms or molecules, which releases energy in the form of heat or light.

Exothermic reactions play an important role in many natural and industrial processes, including respiration, photosynthesis, and the production of electricity in power plants.

The new pressure of gas when the volume of the gas is increase to 321 L at 125 °C is 212.46 torr

How to determine the new pressure

The new pressure of the gas can be obtained by using the Boyle's law equation since the temperature is constant. This is illustrated below:

P₁V₁  = P₂V₂

248 × 275 = P₂ × 321

68200 = P₂ × 321

Divide both side by 321

P₂ = 68200 / 321

P₂ = 212.46 torr

Answer:

Explanation:

The molar mass of this compound is 0.004 m/g

Firstly, molar mass is moles/grams so we need to solve for the number of moles and we were already given the grams (205 g).

So to solve for moles we were given 205 g, 20.0 L, 273 K and 1.00 atm. Knowing these numbers we can plug them into the ideal gas law, PV=nRT

where P is pressure, V is volume, n is number of moles, R is the gas constant (in this case it is 0.08206) and T is the temperature.

[tex]PV=nRT\\\\n=\frac{PV}{RT}\\\\n=\frac{1.00*20.0}{0.08206*273} =0.893[/tex]

Next, we use moles and grams to solve for molar mass:

[tex]\frac{0.893}{205} =0.004[/tex]

As temperature increases, the average kinetic energy of a sample of gas molecules decreases.

Answer:

45830.4 moles

Explanation:

Ideal gas law is the hypothetical equation in which the pressure, volume, and temperature of the gas are directly related. It can be denoted as:

PV = nRT

The ideal gas law is:

PV = nRT

where,

P = Pressure

V = Volume

R = Gas constant

T =Temperature

n = moles

Given:

Moles in container = 1.95

Temperture = 294.85 K

Pressure = 3.75 atm

Volume =?

Substituting the values:

V = nRT/P

V = 1.95 × 0.082 × 294 / 3.75

Volume = 12.5 L

Now, the condition when changed, such that temperature is 301.25 K, pressure is 0.998 atm, and Volume is 12.5 L, then moles will be equal to:

PV/RT = n

0.998 × 12.5 / 0.082 × 301.25 = n

n = 45830.4 moles

Therefore, 0.521 moles is still present in the container.
