Answer:

Thermal energy depends on mass and temperature.

Explanation:

The two factors on which thermal energy depends are the mass of an object and temperature.

Thermal energy is defined as a type of energy which is contained within a system which is responsible for temperature rise.Heat is a type of thermal energy.It is concerned with the first law of thermodynamics.

Thermal energy arises from friction and drag.It includes the internal energy or enthalpy of a body of matter and radiation.It is related to internal energy and heat .It arises when a substance whose molecules or atoms are vibrating faster.

These vibrating molecules and atoms collide and as a result of which heat is generated in a substance , more the collision of particles , higher is the thermal energy.There are the three types of thermal energy.

Hopefully this isnt too late!

Answer:

C. Methane

(Photo for proof at the bottom.)

Explanation:

All amino acids contain an amino group, a carboxyl group, and an R group. An amino group consists of NH2. A carboxyl group consists of COOH. And an R group usually consists of a hydrogen or carbon atom bonded to the amino acid. Methane only consists of CH4, which clearly does not meet the criteria of an amino acid.

Answer:

x = 3/6.02 = 0.50.

Explanation:

1 mole of CO2 has 6.02 x 10^23 molecules of CO2.

Say x moles of CO2 has 3.0x10^23 molecules of CO2.

Therefore x = 3/6.02 = 0.50.

Answer:

[tex]3H_2O+(Bi^{5+}O_3)^-\rightarrow Bi^{3+}+6OH^-[/tex]

Explanation:

Hello there!

In this case, according to the required half-reaction, we start by setting it up from bismuth (V) oxide ion to bismuth (III) ion:

[tex]BiO_3^-\rightarrow Bi^{3+}[/tex]

Thus, next realize that the oxidation state of Bi in BiO3^- is 5+ because oxygen is 2- (-2*3+x=-1;x=-1+6;x=+5), so we obtain:

[tex](Bi^{5+}O_3)^-\rightarrow Bi^{3+}[/tex]

Thereafter, we realize three water molecules are needed on the right in order to balance the oxygens and consequently 6 hydrogen atoms on the left to balance hydrogen:

[tex]6H^++(Bi^{5+}O_3)^-\rightarrow Bi^{3+}+3H_2O[/tex]

Now, since the balance is is basic media, we add six molecules of hydroxide ions in order to produce water with the hydrogen ones:

[tex]6OH^-+6H^++(Bi^{5+}O_3)^-\rightarrow Bi^{3+}+3H_2O+6OH^-\\\\6H_2O+(Bi^{5+}O_3)^-\rightarrow Bi^{3+}+3H_2O+6OH^-\\\\6H_2O-3H_2O+(Bi^{5+}O_3)^-\rightarrow Bi^{3+}+6OH^-[/tex]

Then, we accommodate the waters to obtain:

[tex]3H_2O+(Bi^{5+}O_3)^-\rightarrow Bi^{3+}+6OH^-[/tex]

Answer:

(14)The pH is 8.3 and is basic

(15) pOH = 11.0 The solution is acidic

Explanation:

(14) From the question,

pH = -log[H₃O⁺]............... Equation 1

Given: H₃O⁺ = 5.6×10⁻⁹ M

Substitute the value above into equation 1

pH = -log[5.6×10⁻⁹]

pH = 8.3

The pH is 8.25 and is basic.

(15)

pOH = -log[OH⁺]................ Equation 2

Given: [OH⁺] = 8.34×10⁻¹² M

Substitute into equation 2

pOH = -log[8.34×10⁻¹²]

pOH = 11.0 Hence the solution is acidic

The rock cycle basically tell you how the different types of rocks are related to each other and tells how they change over time.

Hope this helped!!!

Answer:

The rock cycle is the process by which rocks of one kind change into rocks of another kind. Metamorphic rock is igneous or sedimentary rock that has been heated and squeezed. It can erode into sediment or melt into a hot substance known as refordium. It is formed under extreme pressure and temperature deep inside mountain chains. For example, sedimentary rock shale becomes slate when heat and pressure are added, thus transforming it into another state of rudementury.

Answer:

Though a hydrogen atom has only one electron, it contains a large number of shells, so when this single electron jumps from one shell to another, a photon is emitted, and the energy difference of the shells causes different wavelengths to be released. Hence, mono-electronic hydrogen has many spectral lines.

Explanation:

Hello there!

In this case, in agreement to the Charles' law which states that the volume and temperature relate to each other via a directly proportional relationship at constant pressure, we can write:

[tex]\frac{T_2}{V_2} =\frac{T_1}{V_1}[/tex]

Thus, given V1, V2 and T1 (310 in Kelvin), we can solve for the final temperature as shown below:

[tex]T_2=\frac{T_1V_2}{V_1} \\\\T_2=\frac{310K*32.5mL}{45.8mL}\\\\T_2=220 K-273.15K\\\\T_2=-53.15\°C[/tex]

Taking into account the definition of density,  the mass of an object with a volume of 2.0 mL and a density of 28.8 [tex]\frac{g}{mL}[/tex] is 57.6 grams.

But first you must know the definition of density. Density is defined as the property that matter, whether solid, liquid or gas, has to compress into a given space.

In other words, density is a quantity that allows us to measure the amount of mass in a certain volume of a substance. Then, the expression for the calculation of density is the quotient between the mass of a body and the volume it occupies:

[tex]density=\frac{mass}{volume}[/tex]

From this expression it can be deduced that density is inversely proportional to volume: the smaller the volume occupied by a given mass, the higher the density.

In this case, you know that:

Replacing in the definition of density:

[tex]28.8 \frac{g}{mL} =\frac{mass}{2 mL}[/tex]

Solving:

mass= 28.8 [tex]\frac{g}{mL}[/tex] ×2 mL

mass= 57.6 g

In summary, the mass of an object with a volume of 2.0 mL and a density of 28.8 [tex]\frac{g}{mL}[/tex] is 57.6 grams.

Answer: 6.38 moles of [tex]O_2[/tex] are needed to react with 2.55 mol of [tex]C_2H_2[/tex]

Explanation:

The balanced chemical reaction for the combustion of ethyne is:

[tex]2C_2H_2+5O_2\rightarrow 4CO_2+2H_2O[/tex]

According to stoichiometry:

2 moles of [tex]C_2H_2[/tex] require = 5 moles of [tex]O_2[/tex]

Thus 2.55 mol of [tex]C_2H_2[/tex] require = [tex]\frac{5}{2}\times 2.55=6.38[/tex] moles of [tex]O_2[/tex]

Thus 6.38 moles of [tex]O_2[/tex] are needed to react with 2.55 mol of [tex]C_2H_2[/tex]

Answer: [tex]Molarity=Normality\times \frac{gew}{gmw}[/tex]

Explanation:

Molarity is defined as the number of moles dissolved per liter of the solution.

[tex]Molarity=\frac{\text {moles of solute}}{\text {Volume in L}}[/tex]

[tex]{\text {moles of solute}=\frac{\text {given mass}}{\text {Molar mass}}[/tex]  

Normality is defined as the number of gram equivalents dissolved per liter of the solution.

[tex]Normality=\frac{\text {gram equivalents of solute}}{\text {Volume in L}}[/tex]

[tex]{\text {gram equivalents of solute}}=\frac{\text {given mass}}{\text {Equivalent mass}}[/tex]

Thus [tex]Molarity=Normality\times \frac{\text {Equivalent mass}}{\text {Molar mass}}[/tex]
