Considering the Charles's law, the sample of carbon dioxide gas will occupy 308.72 mL.

Charles's law establishes the relationship between the temperature and the volume of a gas when the pressure is constant. This law says that the volume is directly proportional to the temperature of the gas: for a given sum of gas at constant pressure, as the temperature increases, the volume of the gas increases and as the temperature decreases, the volume of the gas decreases.

Mathematically, Charles's law states that the ratio between volume and temperature will always have the same value:

[tex]\frac{V}{T} =k[/tex]

Considering an initial state 1 and a final state 2, it is fulfilled:

[tex]\frac{V1}{T1} =\frac{V2}{T2}[/tex]

In this case, you know:

Replacing in Charles's law:

[tex]\frac{250 mL}{298 K} =\frac{V2}{368 K}[/tex]

Solving:

[tex]V2=368 K\frac{250 mL}{298 K}[/tex]

V2= 308.72 mL

Finally, the sample of carbon dioxide gas will occupy 308.72 mL.

The metal which will reach the highest temperature is the metal with the lowest specific heat capacity.

The amount of heat Q = mcΔT where

Making ΔT subject of the formula, we have

ΔT = Q/mc

Given that Q and m are the same for each metal,

ΔT ∝ 1/c

We see that the temperature change is inversely proportional to the specific heat capacity.

Since the metals are at the same temperature, the metal which will reach the highest temperature is the metal with the lowest specific heat capacity.

So, the metal which will reach the highest temperature is the metal with the lowest specific heat capacity.

Answer:

= 62g

Explanation:

We have been asked to find the mass of Na2O having 6.02 x 10^23 units.

We know that one mole of a substance contains 6.02 x10^23 units/particles.

That means we have one mole of Na2O.

To find the mass of Na2O we use the formula,

mass = number of moles x formula mass

= 1 mole x 62g/mol

= 62g

Therefore the mass of Na2O with 6.02 x 10^23 units is 62g.

The required energy will be "87752 J".

The definition of energy is "ability to do work," which is the capacity to apply a force that causes an item to move.

Mechanical, heat, chemical, electrical, radiant, nuclear, and sound are the seven types of energy.

The energy will be:

Q1 = 36 × 3.18(100-65)

Q1 = 5267 J

Moles of water = [tex]\frac{36.0}{18}[/tex]

Moles of water = 2

then,

Q2 = 2× 40.7

Q2 = 81.4 KJ

Q2 = 81400 J

Q3 = 36.0 × 2.01(115-100)

Q3 = 1085 J

hence,

Required energy will be= Q1+ Q2+ Q3

Required energy = 5267 + 81400 + 1085

Required energy = 87752 J

Explanation:

The change in enthalpy for the reaction per mole is -130KJ/mol.

Given,

Reaction: MgO(s) + 2HCl (aq) →MgCl₂ (aq) + H₂O (l)

1.32 g MgO is combined with 100.0 mL of 1.00 M HCl in the cup of coffee.

Change in temperature, ΔT=34.4 °C-24.2 °C =10.2°C

Specific heat of the HCl solution, c= 4.18 J/g·°C

Density= 1.00 g/mL

Mass can be written as the product of density and volume.

Mass= Density × Volume= 1g/ml × 100 ml=100g

Heat can be written as

Heat, Q=mcΔT=100g×4.18 J/g·°C×10.2°C=4263.6J

Number of moles of the MgO,

n= (mass of MgO)/(Molar mass)= 1.32g/(40.3g/mol)= 0.03275 mol

Change in Enthalpy, ΔH=-Q/(n)=(-4263.6J)/(0.03275 mol)

ΔH= -1300186J/mol= -130KJ/mol

Hence, the change in enthalpy for the reaction per mole is -130KJ/mol.

Answer:

the answer will be false.

Explanation:

because it is not balanced.

C. PH3 represents a compound commonly known as phosphine, whose IUPAC name is phosphorus trihydride.

The electronegativity of PH3 found in the Periodic Table of the Period attracts covalent electron pairs and creates covalent bonds. However, because the electrons are not bound, asymmetrical rate distribution occurs. Therefore, PH3 is a polar molecule with a non-polar covalent bond and currently has no polar bond.

A covalent bond consists of sharing one or more electron pairs between two atoms. These electrons are attracted to two nuclei at the same time. Covalent bonds are formed when the difference in electronegativity between two atoms is too small for electron transfer to form ions.

Answer:

Because of gravity and as a result, created planets and stars.

(Likely by a nearby supernova shockwave also)

Although I'm not an expert, I seem to recall reading that solar systems often begin with clouds of unorganized matter measuring 20 parsecs (65 light years) across. Most of them are hydrogen molecules. The pressure required to hold the molecules together increases with temperature, but because the typical temperature is around 12 k, the pressure is negligible. It originates from the gravity of the cloud itself. Material from novas, colliding neutron stars, and high-speed material jets emerging from stars and black holes all contribute to the continuous enrichment of such clouds. That adds those heavy elements—like gold—that can only be produced by the rapid neutron capture (rNC) process as opposed to the simple nuclear fusion process (slow neutron capture). These clouds spontaneously emerge from floating pieces of material, hold together for millions of years, and eventually disperse. A component of the cloud condenses along the route for a variety of causes, including localized concentrations of greater density or shock waves from supernovae. Unbalances in the cloud lead it to split up when condensation takes place. Then those fragments shatter once again, leaving you with barely enough for a solar system. It would have been within 3.5 light years of the initial cloud for our galaxy. The contraction up to this point has been isothermal, which means that heat is being radiated so quickly that temperature stays mostly unchanged. The creation of a Bonnor-Ebert sphere comes next. Although such zones frequently appear in photographs in a faint manner, this is only a hypothetical area in which there is a certain amount of mass. The First Hydrostatic Core is located here (FHSC or First Core). The First Core can be imagined as a pre-proto Sun with an interior temperature of roughly 300 k and a radius of 1 AU (the same as the Earth's orbit) (26.85 C or 80.33 F). Although it first begins off chilly, it ultimately warms up to 300 k and then grows even hotter over the course of years. The friction of falling materials and adiabatic contraction provide the heat (the kind that makes things hotter). Hydrogen molecules start to break down into atomic hydrogen, which is more dense and falls to the center, at temperatures between 1500 k and 2000 k, on average. Eventually, the atomic hydrogen coalesces into a protostar-sized Second Core. Because the entire system is rotating swiftly and because momentum is being lost in some areas owing to gas shooting off, an accretion disk has already formed. Although in our instance it would have also been a protoplanetary disk, the disk is a protostellar disk. The protostar is regarded as a star until it becomes hot and brilliant enough to begin ejecting the gas and dust. (Prior to it, infalling gas and dust are still adding mass to the protostar.)

In the nebular hypothesis, the collapse of the nebula is believed to have been triggered by a disturbance or shock wave, such as a nearby supernova explosion or the gravitational influence of a passing star or gas cloud.

This disturbance caused the nebula, which was a large and diffuse cloud of gas and dust in space, to start collapsing under the force of its own gravity. As the nebula contracted, its particles came closer together, and the conservation of angular momentum caused it to spin faster.

The collapse and spin eventually led to the formation of a rotating protostellar disk at the center, which eventually evolved into a young star, while the surrounding material formed planets and other celestial bodies through accretion and gravitational attraction.
