Answer:

6.022  ×10(index 23) / 7.5 = 0.8293 ×10(index 23)

Explanation:

molar mass of C =  12gmol

therefore in 12g of C there is one mole or an amount of 6.022 ×10(index 23)

∴12g/6.02210(index 23) ×1.6g

We have that for the Question "" it can be said that the mass (in grams) of 3.03 × 1024 molecules of carbon dioxide molecules is

From the question we are told

What is the mass (in grams) of 3.03 × 1024 molecules of carbon dioxide molecules?

Generally the equation for the   is mathematically given as

[tex]No moles in 3*02*10^{24}=\frac{3.03*10^{24}}{6.023*10^-{23}}[/tex]

No moles in 3*02*10^{24}=5.03moles

Amount of CO_2(g)=5.03moles *44g/mol

Amount of CO_2(g)=221.35g

Hence

the mass (in grams) of 3.03 × 1024 molecules of carbon dioxide molecules is

Amount of CO_2(g)=221.35g

Answer:

Tungsten(VI) fluoride, also known as tungsten hexafluoride, is an inorganic compound with the formula WF6. It is a toxic, corrosive, colorless gas, with a density of about 13 g/L (roughly 11 times heavier than air.[

Explanation:

The WF6 molecule is octahedral with the symmetry point group of Oh. The W–F bond distances are 183.2 pm. Between 2.3 and 17 °C, tungsten hexafluoride condenses into a pale yellow liquid having a density of 3.44 g/cm^3 at 15 °C. At 2.3 °C it freezes into a white solid having a cubic crystalline structure, the lattice constant of 628 pm, and a calculated density of 3.99 g/cm^3. At −9 °C this structure transforms into an orthorhombic solid with the lattice constants of a = 960.3 pm, b = 871.3 pm, and c = 504.4 pm, and the density of 4.56 g/cm3. In this phase, the W–F distance is 181 pm, and the mean closest intermolecular contacts are 312 pm. Whereas WF6 gas is one of the densest gases, with the density exceeding that of the heaviest elemental gas radon (9.73 g/L), the density of WF6 in the liquid and solid-state is rather moderate. The vapor pressure of WF6 between −70 and 17 °C can be described by the equation

log10 P = 4.55569 −

where the P = vapor pressure (bar), T = temperature (°C).

Answer:

Pressure increases

Explanation:

According to Gay-Lussac's law, the pressure of a given amount of gas is directly proportional to the temperature at a given volume i.e.

[tex]P\propto T[/tex]

It means the relationship between the pressure and the temperature is direct.

If the temperature increases, the pressure of the gas also increases. Hence, the correct option is (A).

Answer:

I was looking for this same answer.

Explanation:

If the [H₃O⁺] of a solution is less than the [OH⁻], then the solution would have a higher pH than its pOH.

pOH is define as the negative logarithm of the concentration of OH⁻ ion and for a basic solution its value should be less than 7.

In the question it is clear that concentration of H⁺ ion is les than the concentration of OH⁻ ion, so the given solution is basic in nature. Basicity of basic solution is calculated by using the pOH scale and for this solution value of pOH is less than 7, because more than 7 shows the acidic character. And according to the pH scale value of this solution should be more than 7.

Hence, option (A) is correct i.e. The solution would have a higher pH than its pOH.

Volume stays constant, so: P1/T1 = P2/T2

P1 = 3 atm

T1 = 20*C = 293 K

P2 = ?

T2 = 50*C = 323 K

Solve for P2: P1T2/T1 = P2

P2 = (3 atm)(323 K)/(293 K) = 3.3 atm

The Pressure of N2 after its temperature increased will be "3.3 atm". To understand the calculation, check below.

According to the question,

Pressure, P₁ = 3 atm

Temperature, T₁ = 20°C or,

                           = 293 K

                      T₂ = 50°C or,

                           = 323 K  

We know the relation,

→ [tex]\frac{P_1}{T_1}[/tex] = [tex]\frac{P_2}{T_2}[/tex]

or,

Pressure, P₂ = [tex]\frac{P_1\times T_2}{T_1}[/tex]

By substituting the values,

                     = [tex]\frac{3\times 323}{293}[/tex]

                     = [tex]\frac{969}{293}[/tex]

                     = 3.3 atm

Thus the above response is correct.

Answer:

The chemistry will need 2*10⁶ moles of antimony trifluoride.

Explanation:

The balanced reaction is:

3 CCl₄ (g) + 2 SbF₃ (s) → 3 CCl₂F₂(g) + 2 SbCl₃ (s)

By reaction stoichiometry (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of each compound participate in the reaction:

You can apply the following rule of three: if by reaction stoichiometry 3 moles of freon are produced by 2 moles of antimony trifluoride, 3*10⁶ moles of Freon are produced from how many moles of antimony trifluoride?

[tex]moles of antimony trifluoride=\frac{3*10^{6} moles of freon*2 moles of antimony trifluoride}{3 moles of freon}[/tex]

moles of antimony trifluoride= 2*10⁶

The chemistry will need 2*10⁶ moles of antimony trifluoride.

Answer:B

Explanation:

Answer: Rocks formed in this way include halite, gypsum, anhydrite, and some limestones. Layers of precipitated rocks are called evaporite deposits because they typically form where evaporation is high in arid regions like the desert southwest and in the eastern Mediterranean.

Explanation:

The three sedimentary rocks form from chemical precipitates and evaporites are halite, gypsum and anhydrite.

Pre-existing rocks or bits of once-living animals constitute sedimentary rocks. They are formed by the accumulation of sediments on the Earth's surface.

Halite, gypsum, anhydrite, and various limestones are examples of such rocks. Evaporite deposits are layers of precipitated rocks that occur in arid locations like the desert southwest and the eastern Mediterranean where evaporation is considerable.

Hence three sedimentary rocks are Halite, gypsum and anhydrite.
