Combustion of 31.68 g of a compound containing only carbon, hydrogen, and oxygen produces 36.67 g CO₂ and 15.01 g H₂O. the empirical formula of the compound is CH₂O.

given that :

mass of CO₂ = 36.67 g

mass of H₂O = 15.01 g

total mass of compound = 31.68 g

moles of CO₂ = 36.67 / 44

                       = 0.833 mol

moles of C = 0.833 mol

moles of  H₂O = 15.01 / 18

                        = 0.833 mol

moles of H = 2(0.833)

                  = 1.667 mol

mass of carbon = 0.833 × 12

                           = 10 g

mass of hydrogen = 1.667 × 1

                               = 1.667 g

mass of oxygen = 31.68 - ( 10 + 1.67 )

                             = 20 g

moles of Oxygen = 20 / 16

Neutron is not attracted to the positively charged nucleus since it has no charge. As a result, a neutron can bombard a nucleus even if it is very weak.

As a result, a nuclear reaction can be started by even a very weak neutron bombarding a nucleus. Thus, in a nuclear reaction, a neutron is employed to bombard the nucleus. Neutrons have no charge, therefore they are neither drawn to nor repelled by atoms' nuclei and electrons. Neutron is therefore the best projectile. The connections holding the nucleus together contain enormous energy. These connections can be broken, which will release the nuclear energy.

Answer:

only molecules with polar bonds may have a permanent dipole moment.

Explanation:

Answer:

2.02 L

Explanation:

The volume of a gas is directly proportional to its temperature, according to the ideal gas law. This means that as the temperature of a gas decreases, its volume will also decrease.

To determine the new volume of the balloon as the temperature drops from 311 K to 295 K, we can use the ideal gas law to calculate the new volume of the gas:

PV = nRT

Where:

P = the pressure of the gas (assuming it remains constant)

V = the new volume of the gas

n = the number of moles of the gas (assuming it remains constant)

R = the universal gas constant

T = the new temperature of the gas

Since we know the pressure, number of moles, and universal gas constant, we can solve for the new volume of the gas by substituting in the known values and solving for V:

V = nRT / P

Substituting in the values from the problem, we get:

V = (n * R * 295 K) / P

Since the number of moles and the universal gas constant are constants, we can simplify the equation to:

V = k / P

Where k is a constant equal to the product of the number of moles, the universal gas constant, and the original temperature of the gas (in this case, k = n * R * 311 K).

Since we know the value of k and the pressure of the gas, we can solve for the new volume of the gas by substituting in the known values:

V = (k / P)

= (n * R * 311 K) / P

= (2.07 L * 8.31 L * atm / mol * K * 311 K) / P

= 2.02 L

Therefore, the new volume of the balloon is approximately 2.02 L.

Among the given statements, A) The entropy of the universe increases and tends towards maximum value is TRUE.

Entropy is a metric for system disorder. The amount of energy that cannot be used for work is also referred to as entropy. Less of a system's energy is available to perform work the more disorganized it is and the higher its entropy.

The overall entropy of a system never decreases; according to the second law of thermodynamics, it always either rises or stays the same. It always tends towards maximum value. This law has a crucial implication: heat spontaneously transfers energy from higher- to lower-temperature objects, but never in the opposite direction. Entropy increases when heat is transferred from a hot environment to a cold environment.

An organism's genotype is the complete set of its genetic material. [1] Genotype can also be used to refer to the alleles or variants that an individual has at a particular gene or locus. The number of alleles an individual can have for a particular gene depends on the number of copies of each chromosome (also called polyploidy) found in that species. Diploid species like humans have two complete sets of chromosomes. This means that each individual has her two alleles for a particular gene. If both alleles are the same, the genotype is said to be homozygous. If the alleles are different, the genotype is called heterozygous.

Explanation:

Choloracetic acid, 12 g. The colorless solution of the white crystalline substance known as chloroacetic acid.

Up to 80% of the solution can be acidic. By inhalation, ingestion, and skin contact, it is poisonous. It corrodes flesh and metals.

The equilibrium of the buffer is

CH2ClCO2 + H+ HCH2ClCO2

PKA = Log Ka

Ka: [CH2ClCO2] = 1,3 x 103. "H+" / "HCH2ClCO2"

Using the Henderson-Hasselbalch formula:

pH equals pka plus log10 [A]/[HA].

2,89 + log10 [A] / [HA] = 3,01

1,318 = [A⁻] / [HA]

Since chloroacetic acid (HA) has a molar concentration of 0,20M

[A⁻] = 0,26 mol/L

There are 500 mL plus 0.5 L.

Chloroacetic acid is equal to 0,26 mol/L x 0,5 l, or 0,13 moles. By weight:

The energy required to bring 120 g of acetic acid (HCH3CO2) to a boil at a starting temperature of 16.7 °C is 72.2116 kJ.

Given that ;

mass of acetic acid = 120.0 g

initial temperatureT₁  = 16.7 °C  = (16.7 + 273.15 ) K = 298.85 K

standard molar mass of acetic acid = 60.052  g/mol

The number of moles of acetic acid can therefore be calculated as follows: number of moles of acetic acid = mass of acetic acid/molar mass of acetic acid

number of moles of acetic acid = 120.0 g/ 60.052 g/mol

number of moles of acetic acid =  1.998 moles

For acetic acid:

standard boiling point T₂  = 118.1 °C = ( 118.1 + 273.15 ) K = 391.25 K

enthalpy of vaporization of acetic acid ΔH[tex]_{vap}[/tex]  = 23.7 kJ/mol

heat capacity of acetic acid  c = 2.043  J/g.K

change in temperature Δ T =  T₂ - T₁

Δ T = (391.25 - 289.85)K

Δ T = 101.4 K

The heat required to raise the liquid acetic acid's temperature from 16.7°C to its boiling point is;

q = mcΔT

From our values above;

q = 120 g ×  2.043  J/g.K × 101.4 K

q = 24859.2  J

q = 24859 /1000 kJ

q = 24.859 kJ

We already determined that we have 1.998 moles of acetic acid;

Thus;

the needed amount of heat = Δ[tex]_{vap}[/tex]*number of moles

The needed amount of heat = 47.3526 kJ

Hence;

The total amount of heat needed = 24.859 kJ + 47.3526 kJ

Water is a polar molecule because in the O-H bond of water, Oxygen is more electronegative due to which partial positive charge and partial negative charge is created on hydrogen and oxygen respectively, resulting in a dipole moment.

A dipole moment is created between two atoms having a suitable electronegativity (ability to pull electrons more towards itself) difference.

A difference in electronegativity between two atoms creates a partial positive charge and a partial negative charge on the atoms. The electrons are pulled towards the atom having partial negative charge. The resultant direction of the atoms in which they get pulled gives the dipole moment of the bond.

If the resultant dipole is zero then the bond is considered to be non-polar

water is an example of a polar molecule as in the bent structure of the molecule, with oxygen at the center, surrounded by two H atoms on both sides, the electrons of the two O-H bonds are pulled towards O, resulting in a dipole moment in the upward direction. Thus, making water a polar molecule.
