What is the total pressure of a container in kpa if the partial pressures are 1.25 atm and 66.7 psi?

Answers

Answer:

586 kpa(kilopascal/1000 pascals)

Explanation:

given 1.24 atm(standard atmosphere), and 66.7 psi(pound force per square inch).

To find the total pressure we should use dalton's law of partial pressures which is the sum of the pressures of each individual gas.

then we convert them to pascals and divide by 1000 to get the measurement in kilopascal.

knowing that 1 atmosphere is proportional to around 14.696 psi. We can multiply our given measure of atm by that and sum it by psi like so. 1.24×14.6959 = 18.22298.

Then,

18.22298+ 66.7 = 84.92298

psi.

Since 1 psi is proportional to around 6894.76 pascals. 1 psi will be 68.9476 kilopascal. 84.92298 * 6.89476 = 585.523336 ≈ 586

The azimuthal quantum number and magnetic quantum number corresponds to the s orbital is zero. Hence, there is only one m value and thus contains one orbital only.

What are quantum numbers ?

The quantum numbers are numbers used to describe the position of an electron within an orbital. The principal quantum number n indicates the main energy level. The azimuthal quantum number l indicates the shape and type of orbital which have values from 0 to n-1.

The magnetic quantum number m indicates the number of orbitals for a sublevel. m can have values from + l to -l. The fourth quantum number s is called spin quantum number. For an electron the spin quantum number can be +1/2 or -1/2.

The n value for the 6s sublevel is 6. The azimuthal quantum number , l for an s orbital  is zero. So its m quantum number has only one value that is zero. Hence, there is only one orbital in 6s sublevel.

What type of bond is present between two atoms of zinc in a nickel

Answers

Answer:

Pure covalent

Explanation:

To know the type of bond between two atoms you must find the electronegativity difference of them:

If electronegativity difference is:

< 0.4: Pure covalent.

Between 0.4 and 1.8: Polar covalent.

> 1.8: Ionic.

The electronegativity of Zn is 1.65 and Ni is 1.91. Electronegativity difference is:

1.91 - 1.65 =  0.26

That means the type of bond is:

Pure covalent

A mineral breaks into cubes when struck with a rock hammer. It also leaves a red trail when scraped against an unglazed porcelain plate.

Which of the mineral's properties are being measured?

Choose the two correct answers.


streak

color

cleavage

hardness

Answers

The two properties which can be measured from the given information are streak and cleavage of the mineral.

What are minerals?

Minerals are naturally forming inorganic substances having crystal structure and metallic characteristics. They have a definite chemical composition and  homogeneity.

Streak is the color of powder form of mineral and cleavage is how the mineral cleave when we cut through a plane.  Hardness says how much hard the solid is.

When the mineral breaks into cubes when struck with a hammer, we measure its cleavage properties. The red trail on scrapping indicates the streak of the mineral.

Hence, the two properties we can measure from breaking by hammer and scrapping by an unglazed porcelain are its cleavage and streak.

An antacid tablet contains 640.0 mg of magnesium oxide per tablet.
What volume of 0.1000 M stomach acid (HCI) could one tablet neutralize?​

Answers

Answer:

317.6 mL

Explanation:

Step 1: Write the balanced neutralization equation

MgO + 2 HCl ⇒ MgCl₂ + H₂O

Step 2: Calculate the mass corresponding to 640.0 mg of MgO

The molar mass of MgO is 40.30 g/mol. The moles corresponding to 640.0 mg (0.6400 g) of MgO are:

0.6400 g × (1 mol/40.30 g) = 0.01588 mol

Step 3: Calculate the moles of HCl that react with 0.01588 moles of MgO

The molar ratio of MgO to HCl is 1:2. The moles of HCl are 2/1 × 0.01588 mol = 0.03176 mol

Step 4: Calculate the volume of 0.1000 M HCl that contains 0.03176 moles

0.03176 mol × (1 L/0.1000 mol) = 0.3176 L = 317.6 mL

The liquid can be identified

Explanation:

Given that density is defined as mass per unit volume.

We have the following information regarding the unknown liquid;

Mass= 1.40 kg = 1400 g

Volume = 1378 cm^3 = 1378 ml

Density of unknown liquid = 1400/1378 = 1.012 g/ml this is approximately 1.0 g/ml

It is possible to identify the liquid, the liquid is ethanolamine

A. 129
B. 0.360
C. None of the above
D. 0.106
E. 13

Answers

Answer:

The correct answer is C. None of the above.

Explanation:

To determine how long the black bear will run, the distance it will travel must first be determined. Thus, the proposed calculation must be solved.

1.95 x 10 ^ 4

1.95 x 10 x 10 x 10 x 10

19.5 x 10 x 10 x 10

195 x 10 x 10

1950 x 10

19500

Thus, the bear will run 19,500 miles, so, running at 35 mph, it will take about 557 hours to run that distance (19,500 / 35).

Answer:

The correct approach is "3.1×10⁻³ M".

Explanation:

As we know,

[tex]pH=-log[H_{3}O^+][/tex]

[tex]pH=2.5[/tex]

[tex][H_{3}O]^+= \ ?[/tex]

Now,

⇒ [tex]-log[H_{3}O]^+=2.5[/tex]

⇒ [tex][H_{3}O]^+=10^{-2.5}[/tex]

⇒             [tex]=3.1\times 10^{-3} \ M[/tex]

So that the needed molar concentration of HCL will be:
