.25 g of each of the following gasses are taken at 27°C and 600 mm
Hg pressure. Which of these will have the least volume?
(Molar mass (g/mole): HCI = 36.5, HBr = 81, HI = 128, HF = 20)
(R=0.082 Latm/K.mole)
A. HC1
B. HBr
C. HI
D. HF

Answers

HI has the least volume

Further explanation

Given

Gasses and molar mass

Required

The least volume

Solution

Ideal gas law

PV=nRT

V = (nRT)/P

n = mass : MW(Molar weight=molar mass)

[tex]\tt V=\dfrac{\dfrac{mass}{MW}RT }{P}\\\\V=\dfrac{mass.RT}{MW.P}[/tex]

so V is inversely proportional to MW(molar mass)

Because the values of P, R, T, and mass are the same, what matters is the value of the molar mass of each compound. The larger the molar mass the smaller the volume

From the available molar mass data, HI has the largest molar mass, so HI has the smallest volume

A photocopier is making reduced copies of a photo that measures 25 centimeters in height. The height of the first copy is​ 80% of the height of the original. Another copy is made using the first​ copy, and the height of this copy is​ 85% of the height of the first copy. Answer parts a and b.​

Answers

Answer:The height of First Copy is 20 cm.

Step-by-step explanation:

Given:

Original Height = 25 cm

First copy is reduce to 80% of Original height.

Therefore to find the height of first copy can be find out by multiplying 80 with original height and then dividing by 100.

∴ Height of First Copy =

Hence Height of first copy is 20 cm

Now Another copy is reduce to 85% of First Copy.

Therefore to find the height of another copy can be find out by multiplying 85 with first copy height and then dividing by 100.

∴ Height of Another Copy =

Hence Height of Another copy is 17 cm

If a sample contains 22 moles of CsPO4, what is the mass of that sample?

Answers

Answer:

Mass = 5013.36 g

Explanation:

Given data:

Number of moles of CsPO₄ = 22 mol

Mass of sample = ?

Solution:

Formula:

Mass = number of moles × molar mass

Molar mass of CsPO₄ = 132.91×1 + 30.97×1 +16×4 = 227.88 g/mol

by putting values,

Mass = 22 mol ×  227.88 g/mol

Mass = 5013.36 g

Cynthia has 200kg of magnesium. Calculate how much MgCl2 she can make.

Mg + Cl2 = MgCl2

Answers

Answer:

784.4kg

 

Explanation:

Given parameters:

Mass of Mg  = 200kg

Unknown:

Mass of MgCl₂  = ?

Solution:

  The reaction equation is given as:

            Mg  +  Cl₂ →   MgCl₂

Find the number of moles of the given specie;

  Number of moles of Mg = [tex]\frac{mass}{molar mass}[/tex]   = [tex]\frac{200000}{24.3}[/tex]   = 8230.5mole

So;

   1 mole of Mg will produce 1 mole of MgCl₂

 

   8230.5mole of Mg will produce 8230.5mole of MgCl₂

Mass of MgCl₂   = number of moles x molar mass

                    Molar mass of MgCl₂  = 24.3 + 2(35.5) = 95.3g/mol

 Mass of MgCl₂   = 8230.5mole x  95.3g/mol  = 784.4kg

A drop in water temperature is observed when 0.848 g of ammonium nitrate is added. The enthalpy change for this reaction is +0.117 kJ. Calculate the Δ Hrxn, in kJ/mol, for this reaction.

Answers

The Δ Hrxn, in kJ/mol, for this reaction= 11.04 kJ/mol

Further explanation

Given

0.848 g ammonium nitrate

The enthalpy change : +0.117 kJ

Required

Δ Hrxn, in kJ/mol

Solution

Delta H reaction (ΔH) is the amount of heat change between the system and its environment  

The value of ° H ° can be calculated from the change in enthalpy of standard formation:  

∆H ° rxn = ∑n ∆Hf ° (product) - ∑n ∆Hf ° (reactants)  

mass of NH4NO3 = 0.848 g

mol of NH4NO3(MW = 80 g/mol)

mol = 0.848 : 80

mol = 0.0106

The Δ Hrxn :

= 0.117 kJ : 0.0106 mol

= 11.04 kJ/mol

How many seconds in 4.3 years?

Answers

1.356e+8 seconds in a year

In the given question, 136293840 seconds are present in 4.3 years.

A second is a unit of time that is equal to 1/60th of a minute and is used to measure short periods of time.

To convert 4.3 years to seconds, we can use the following conversion factors:

1 year = 365.25 days (accounting for leap years)

1 day = 24 hours

1 hour = 60 minutes

1 minute = 60 seconds

So, we can start by multiplying the number of years by the number of days per year:

4.3 years [tex]\times[/tex] 365.25 days/year = 1577.475 days

Next, we can multiply the number of days by the number of hours per day:

1577.475 days [tex]\times[/tex] 24 hours/day = 37859.4 hours

Then, we can multiply the number of hours by the number of minutes per hour:

37859.4 hours [tex]\times[/tex] 60 minutes/hour = 2271564 minutes

Finally, we can multiply the number of minutes by the number of seconds per minute to get the total number of seconds:

2271564 minutes [tex]\times[/tex] 60 seconds/minute = 136293840 seconds

Therefore, in 4.3 years there are approximately 136293840 seconds.

Water, H2O, frequently forms Hydrogen Bonds with other non metal atoms.

Why does water do this?

A: the Oxygen has a partial negative charge which attracts atoms and molecules that have a position or partial positive charge

B: The Hydrogen has a partial negative charge which attracts atoms and molecules that have a positive or partial positive charge

C: Because Oxygen is extremely electronegative it attracts atoms and molecules with a negative or partial negative charge

D: Because Hydrogen has a very low electronegative rating it attracts atoms and molecules with a positive or partial positive charge

Answers

Answer:

Opposite charges attract one another. The slight positive charges on the hydrogen atoms in a water molecule attract the slight negative charges on the oxygen atoms of other water molecules. This tiny force of attraction is called a hydrogen bond.

Considering the definition of hydrogen bond, the correct answer is option A: he Oxygen has a partial negative charge which attracts atoms and molecules that have a position or partial positive charge.

In hydrogen bonds, a molecule that presents hydrogen interacts with another that presents an atom with high electronegativity, such as oxygen, fluorine or nitrogen (O, F, N). In this way, between the hydrogen, which has a low electronegativity and the electronegative atom, an interaction is established, due to their opposite charges.

On the other hand, electronegativity is the ability of an atom to attract shared electrons in a covalent bond.

In the case of water, because oxygen is more electronegative than hydrogen, electrons, which have a negative charge, are more likely to be closer to the oxygen atom than to the hydrogen atom, which causes each hydrogen atom to have a positive charge is called a positive partial charge, and that of oxygen, a negative charge, since it has the electrons closer together.

In summary, the correct answer is option A: he Oxygen has a partial negative charge which attracts atoms and molecules that have a position or partial positive charge.
