Explanation:

The new pressure can be found by using the formula for Boyle's law which is

[tex]P_1V_1 = P_2V_2[/tex]

Since we are finding the new pressure

[tex]P_2 = \frac{P_1V_1}{V_2} \\[/tex]

From the question

760 mmHg = 1 atm

380 mmHg = 0.5 atm

We have

[tex]P_2 = \frac{0.5 \times 5}{8} \\ = 0.3125[/tex]

We have the final answer as

The net ionic equation for the reaction between iron (iii) sulfate and potassium hydroxide is

Fe³⁺(aq) + 3OH¯(aq) —> Fe(OH)₃(s) (Option B)

Chemical equations are representations of chemical reactions using symbols and formula of the reactants and products.

The reactants are located on the left side while the products are located on the right side.

Reactants —> Products

The balancing of chemical equations follows the law of conservation of matter which states that matter can neither be created nor destroyed during a chemical reaction but can be transferred from one form to another.

In solution

Fe₂(SO₄)₃ (aq) --> 2Fe³⁺(aq) + 3SO₄²⁻(aq)

KOH (aq) --> K⁺(aq) + OH¯(aq)

The reaction proceeds as follow

Fe₂(SO₄)₃ (aq) + KOH (aq) —>

Fe³⁺(aq) + SO₄²⁻(aq) + K⁺(aq) + OH¯(aq) —> Fe(OH)₃(s) + SO₄²⁻(aq) + K⁺(aq)

Cancel out the spectator ions (i.e SO₄²⁻ + K⁺) and balance to obtain the net ionic equation

Fe³⁺(aq) + 3OH¯(aq) —> Fe(OH)₃(s)

Answer:

Q = 802.6 J

Explanation:

Given data:

Specific heat capacity of water = 4.18 J/g.°C

Mass of water = 12 g

Initial temperature = 23°C

Final temperature = 39°C

Heat required = ?

Solution:

Formula:

Q = m.c. ΔT

Q = amount of heat absorbed or released

m = mass of given substance

c = specific heat capacity of substance

ΔT = change in temperature

ΔT = 39°C - 23°C

ΔT = 16 °C

Q = 12 g× 4.18 J/g.°C × 16 °C

Q = 802.6 J

Answer:

Boiling points increase as the number of carbons is increased.

Explanation:

The addition of solutes or other substances usually changes the boiling point. Additionally, changing the pressure on a liquid changes its boiling point. Sugar, salt or other non-volatile solutes in water will usually make the boiling point higher.

The relative strength of the four intermolecular forces is: Ionic > Hydrogen bonding > dipole dipole > Van der Waals dispersion forces. The influence of each of these attractive forces will depend on the functional groups present. Boiling points increase as the number of carbons is increased.

The formula for calculating power is such that;

  power = work/time

Two ways to restate the relationship between the 3 variables would be to make time and work the subject of the formula respectively.

1. When time if made the subject of the formula;

 time = work/time

2. When work is made the subject of the formula;

work = power x time

Answer:

1. Alkali metals (group 1)

2. halogens (Group 17)

3. noble gasses (group 18)

Explanation:

1. alkali metals only have one valence electron meaning that they really want to lose that one valence electron to get a full octet.

2. halogens have 7 valence electrons meaning that they just need to gain 1 to get a full octet.

3. Nobel gasses already have a full octet meaning that they don't want to react. (atoms only react to get a full octet)

Incidentally, they all form dew but because grass is closer to the soil, which maintains heat longer than the air where tree leaves are found, you will find more condensation in that region. Also, higher up the wind and sun will allow faster evaporation which makes the dew less noticable on tree leaves.

Explanation:

Preferred objects of dew formation are thus poor conducting or well isolated from the ground, and non-metallic, while shiny metal coated surfaces are poor infrared radiators. ... If the wet soil beneath is the major source of vapor, however (this type of dew formation is called distillation), wind always seems adverse.

STP

specifies 100⋅kPa,and 273.15⋅K...

Explanation:

And so we solve for n

moles of gas

in the Ideal Gas equation, and of course we have to fish out an appropriate gas constant...

n=PVRT=100⋅kPa×10⋅L8.314⋅L⋅kPa⋅K−1⋅mol−1×273.15⋅K

=0.440⋅mol

And thus a mass of 0.440⋅mol×20.18⋅g⋅mol−1...approx. 9⋅g...

Explanation:

answer: covalent bonds

Answer:

0.008 moles of gas are present

Explanation:

Given data:

Volume of gas = 1.75 L

Number of moles =  ?

Temperature of gas = 58°C

Pressure of gas = 12.5 KPa

Solution:

The given problem will be solve by using general gas equation,

PV = nRT

P= Pressure

V = volume

n = number of moles

R = general gas constant = 0.0821 atm.L/ mol.K  

T = temperature in kelvin

Now we will convert the temperature.

58+273 = 331 K

Pressure = 12.5/101 = 0.12 atm

by putting values in formula:

0.12 atm× 1.75 L = n× 0.0821 atm.L/ mol.K   ×331 K

0.21 atm.L = n× 27.17atm.L/ mol

n = 0.21 atm.L /27.17atm.L/ mol

n = 0.008 mol

Different rock types appear during rock formation. The best description of foliated metamorphic rocks is that;

Due to the pressure and heat that is exerted on some rock types, there is an alignment or foliation of rocks. The appearance can be described as ribbon-like.

The examples of rocks that fall under this classification are slate, phyllite, gneiss, and schist.

The non-foliated rocks do not show any alignment in their minerals. Examples are; quartzite, marble, and novaculite.

Summarily, option B best describes a foliated metamorphic rock.
