If a gas is at a pressure of 46 mm Hg and temperature of 640 K, what would be the temperature if the pressure was raised to 760 mm Hg?

Answers

Answer 1

Answer:

10573.9K

Explanation:

Using pressure law equation;

P1/T1 = P2/T2

Where;

P1 = initial pressure (mmHg)

P2 = final pressure (mmHg)

T1 = initial temperature (K)

T2 = final temperature (K)

According to the information provided in this question,

P1 = 46mmHg

P2 = 760mmHg

T1 = 640K

T2 = ?

Using P1/T1 = P2/T2

46/640 = 760/T2

Cross multiply

640 × 760 = 46 × T2

486400 = 46T2

T2 = 486400 ÷ 46

T2 = 10573.9K

D.
it is absorbed as it strikes the surface of a new medium.

Answers

[tex]\huge{ \mathfrak{  \underline{ Answer }}}[/tex]

Refraction is a phenomenon in which, light bends itself while moving from from one Medium to another. This occurs due to change in speed of light in different mediums.

Therefore correct option is :

A. it changes its direction as it passes into a new medium.

I hope it helped you !!

[tex] \boxed{ \boxed{\huge{ \mathrm{  \underline{ Answer} \:  \:  }}}}[/tex]

The Correct option will be : -

A. it changes its direction as it passes into a new medium.

because, light travels with different speeds in different mediums, and this occurs due to difference in optical density of different mediums.

And bending of light depends upon the change in medium,

for example :

when travelling from optically denser medium to optically rarer medium it bends away from normal.

when travelling from optically rarer medium to optically denser medium it bends towards the normal.

what is the minimum mass of ethylene glycol that must be dissolved in 14.5 kg of water to prevent the solution from freexing at -14.2

Answers

Answer:

The minimum mass of ethylene glycol = 6.641 Kg

Explanation:

[tex]\Delta T_f= T_f-T_f'\\T_f'=T_f-\Delta T_f[/tex]

Where T_f = freezing point of pure solvent water, 0°C

T_f'= Freezing point of solvent after mixture

K_f = Freezing point depression constant = 1.86 °C/m

Moecular weight of ethylene glycol = 60 g/mol

Weight of ethylene glycol = 14.5 Kg= 14.5×10^3 g

molality of ethylene glycol

[tex]m = \frac{weight}{mol.wt} \times\frac{1000}{V}[/tex]

Substitute the values to calculate m

[tex]m = \frac{w}{60} \times\frac{1000}{14.5\times1000}[/tex]

by formula

[tex]0-(-14.2) =1.86\frac{w}{60} \times\frac{1000}{14.5\times1000}[/tex]

calculating we get w = 6641.93 g

Therefore, The minimum mass of ethylene glycol = 6.641 Kg

Inside a car that was at STP, a 0.95 L bottle warms up to 144 C. If the volume of the bottle
remains constant, what is the pressure, in atm, inside the hot water bottle?

Answers

Answer:

1.53 atm

Explanation:

From the question given above, the following data were obtained:

Volume = constant

Initial pressure (P₁) = stp = 1 atm

Initial temperature (T₁) = 273 K

Final temperature (T₂) = 144 °C = 144 °C + 273 = 417 K

Final pressure (P₂) =?

Since the volume is constant, the final pressure can be obtained as follow:

P₁ / T₁ = P₂ / T₂

1 / 273 = P₂ / 417

Cross multiply

273 × P₂ = 417

Divide both side by 273

P₂ = 417 / 273

P₂ = 1.53 atm

Therefore, the final pressure (i.e the pressure inside the hot water bottle) is 1.53 atm.

Answer: water

For many centuries, it was considered that there were only three states of matter: solid, liquid and gas (the three that are present and stable in our world). And water is the substance that best represents them, because it is the only one that exists naturally in the three states.

Explanation: Matter can exist in one of three main states: solid, liquid, or gas.

Solid matter is composed of tightly packed particles. ...

Liquid matter is made of more loosely packed particles. ...

Gaseous matter is composed of particles packed so loosely that it has neither a defined shape nor a defined volume.

Water is the only common substance that is naturally found as a solid, liquid or gas. Solids, liquids and gases are known as states of matter.

If 10.0 moles of NO are reacted with 6.0 moles of O2, How many moles of NO2 are produced?​

Answers

Answer:

We have to find out which of the reactants that is the Limiting Reagent.

The Limiting Reagent is the reactant that finishes before reaction is complete or simply put... Its the reactant that's NOT IN EXCESS.

We use the reactant that's not in excess to find the Number of moles of product because once that reactant is used up.... The reaction also ends or stops(hence the name;Limiting reactant).

Now

We have 10moles of NO

We also have 6moles of O2

The balanced equation of Reaction is

2NO + O2 ===> 2NO2

Now

looking at this equation

2moles of NO is required to react with 1mole of O2

So since we have NO=10moles and O2 = 6moles

It means that

20moles of NO is required to react with 6 moles of O2.

We were only given 10moles of NO and this is not even enough to react with the whole 6moles of Oxygen because from what we just discovered... We need 20moles of NO to react with all 6moles of O2.

So

This means that NO is the LIMITING REACTANT. It is in short supply and would be used up before the whole reaction takes place.

So we use the limiting reactant to find the Number of Moles of Product formed.

Now

From the eqn of reaction

2moles of NO forms 2Moles of NO2.

Their Mole ratio is 2:2 or 1:1...

This simply means that an equal amount of NO2 will be Produced

MEANING.... 10 MOLES OF NO2 IS PRODUCED.

how many grams of cacl2 can be produced from 50.0 grams of hcl

Answers

Answer:

76.0 g

Explanation:

Step 1: Write the balanced equation

2 HCl + Ca(OH)₂ ⇒ CaCl₂ + 2 H₂O

Step 2: Calculate the moles corresponding to 50.0 g of HCl

The molar mass of HCl is 36.46 g/mol.

50.0 g × 1 mol/36.46 g = 1.37 mol

Step 3: Calculate the number of moles of CaCl₂ produced from 1.37 moles of HCl

The molar ratio of HCl to CaCl₂ is 2:1. The moles of CaCl₂ produced are 1/2 × 1.37 mol = 0.685 mol.

Step 4: Calculate the mass corresponding to 0.685 moles of CaCl₂

The molar mass of CaCl₂ is 110.98 g/mol.

0.685 mol × 110.98 g/mol = 76.0 g

How many molecular orbitals are present in the valence band of a sodium crystal with a mass of 4.14 g

Answers

Answer:

Explanation:

Given that:

The mass of sodium crystal = 4.14 g

As a result, the number of atoms in the sodium crystal is:

[tex]=4.14 \g \times \dfrac{ 1 \ mol}{23.0 \ g }\times \dfrac{6.023 \times 10^{23} \ atoms}{1 \ mol}[/tex]

= 1.084 × 10²³ atoms

In the valence orbital of the sodium atom, there is just one electron.

As a result, the number of molecular orbitals produced by these atoms is= 1.084 × 10²³ molecular orbital

Because valence bands are created from occupied molecular orbitals, the number of valence bands created from the aforementioned molecular orbitals is:

[tex]= \dfrac{ 1.084 \times 10^{23}}{2}[/tex]

= 5.420 × 10²² orbitals.

Answers

Answer:

2Mg(s) + O2(g) ----->2MgO(s)

Explanation:

In writing a balanced chemical reaction equation, the rule of thumb is that the number of atoms of each element on the reactant side must be the same as the number of atoms of the same elements on the products side.

Hence for the reaction of magnesium and oxygen shown below;

2Mg(s) + O2(g) ----->2MgO(s)

We notice that there are two atoms each of magnesium and oxygen on both sides of the reaction equation hence the equation is balanced.

A more electronegative atom A) will have more attraction to the electrons in a chemical bond. B) is more likely to lose an electron. C) is less likely to form a chemical bond. D) is more likely to form an ionic bond with another highly electronegative atom.

Answers

Answer: A more electronegative atom will have more attraction to the electrons in a chemical bond.

Explanation:

An atom that is able to attract electrons or shared pair of electrons more towards itself is called an electronegative atom.

For example, fluorine is the most electronegative atom.

Due to its high electronegativity it is able to attract an electropositive atom like H towards itself. As a result, both fluorine and hydrogen will acquire stability by sharing of electrons.

Thus, we can conclude that a more electronegative atom will have more attraction to the electrons in a chemical bond.
