Result:- 121 kPa.

Solution:- The parameters mass, temperature, and volume for carbon dioxide gas are given, and we are tasked with determining the pressure exerted by this gas on the container.

This is based on the ideal gas law equation, PV = nRT.

Where P stands for pressure in atm, V is the volume in liters, n is the gas moles, R is the universal gas constant with its value \frac{0.0821atm.L}{mol.K} and T is the temperature in Kelvin.

Data provided:- mass = 88.0 g

T = 291 K

V = 40.0 L

P =?

We must convert mass into moles by dividing the mass by molar mass, where the molar mass of carbon dioxide is 44.01 grams per mole.

n=88.0g(\frac{1mol}{44.01g})

n = 2.00 mol

Reorganizing the equation for pressure gives us:

P=\frac{nRT}{V}

Let’s substitute the values and calculate for P.

P=\frac{2.00mol*(\frac{0.0821atm.L}{mol.K})*291K}{40.0L}

P = 1.1946 atm

Since the question requests the answer in kPa, we need to convert atm to kPa.

1 atm = 101.325 kPa

Thus, 1.1946atm(\frac{101.325kPa}{1atm})

= 121 kPa

Consequently, the pressure this gas applies on the container is 121 kPa.

Tems11 [2403]

Answer:

When HBCG and BCG^- are at the same concentration, the resulting color is green. This green shade initially becomes visible at a pH of 3.8.

Explanation:

HBCG serves as an indicator formed by dissolving solids in ethanol.

Since

Ka=[BCG−][H3O+][HBCG] When [BCG-] equals [HBCG], it follows that Ka = [H3O+].

<pWith a pH of 3.8,<pKa= [H3O+] = -antilog pH = -antilog (3.8)

Ka= 1.58 ×10^-4

(a) calculate the %ic of the interatomic bond for the intermetallic compound tial3. (b) on the basis of this result, what type o
Tems11 [2403]

Answer :

The percentage ionic character (%IC) equals 10%, indicating the bond is mostly covalent with slight polarity.

Percent Ionic Character:

This reflects the fraction of ionic nature within a polar covalent bond. The formula for %IC (% ionic character) is:

Percent Ionic character = 1 - e^-^0^.^2^5 ^*^(^X^a^-^X^b^) * 100

Here, Xa is the electronegativity of atom A and Xb is that of atom B.

Given: The compound is TiAl₃.

Electronegativity of Ti = 2.0

Electronegativity of Al = 1.6 (as shown in the provided image)

Substitute these values into the formula:

Percent Ionic character = 1 - e^-^0^.^2^5 ^*^(^2^.^0^-^1^.^6^) * 100

Percent Ionic character = 1 - e^(^-^0^.^2^5 ^*^0^.^4^) * 100

Percent Ionic character = 1 - e^(^-^0^.^1^) * 100

The value of e⁻¹ equals 0.90.

Therefore, percent ionic character = (1 - 0.90) × 100

Percent Ionic Character = 10%

Because the % IC is only 10%, which is relatively low, the bond is classified as covalent with minimal polarity.

From the following list of elements, those that will always form ionic compounds in a 1:2 ratio with zinc.
eduard [2520]
A. iodine C. fluorine F. bromine Explanation: Ionic bonds primarily form between metals and non-metals, typically where there exists a significant difference in electronegativity between the constituent atoms. This situation results in one atom seeking to gain electrons while the other donates them. For zinc to form a compound in a 1:2 ratio, its combining power must align accordingly. The prevalent oxidation state of zinc is +2. The other combining atoms must also possess the capacity to accept two electrons. The halogens fit perfectly here, as they require only one electron to achieve stability and are highly electronegative. Hence, if two halogens combine with zinc, they will result in an ionic bond. The relevant halogens include fluorine, chlorine, bromine, iodine, and astatine which will yield compounds: ZnF₂, ZnBr₂, and ZnI₂.
