The empirical formula : C₆H₂Cl₂O

The molecular formula : C₁₂H₄Cl₄O₂

<h3>Further explanation</h3>

Given

The percentage composition

Required

The empirical formula and the molecular formula

Solution

The mol ratio of the components :

C : H : Cl : O

=44.76/12 : 1.25/1 : 44.05/35.5 : 9.94/16

=3.73 : 1.25 : 1.241 : 0.621 divide by 1.241

= 3 : 1 : : 1 : 0.5 x 2

= 6 : 2 : 2 : 1

The empirical formula : C₆H₂Cl₂O

(Empirical formula)n=molecular formula

(C₆H₂Cl₂O)n=321.97

(160.986)n=321.97

n=2

(C₆H₂Cl₂O)₂=C₁₂H₄Cl₄O₂

The molecular formula : C₁₂H₄Cl₄O₂

When a kettle is placed on the stove and water begins to boil, the hotter water at the bottom begins to rise and the cooler wate

melisa1 [442]

I think the correct answer from the choices listed above is option A. The fact that we know about the relationship between the hotter water and the cooler water would be that the <span> hotter water is less dense. Hope this answers the question. Have a nice day.</span>

How much energy is absorbed when a 50.0 gram magnesium strip is heated from 45 degrees to 90 degrees

Leno4ka [110]

Quantity of heat energy required for change of phase= (mass) x (heat of fusion or heat of vaporization), or in equation form Q=mL. Heat of fusion=80cal/g; heat of vaporization=540 cal/g
quanity of heat energy responsible for a temperature change= (mass) x (specific heat) x (change in temperature), or in equation form, Q=mcT

Here's another way to calculate it

Calculate the energy absorbed by 20 grams of 100 C water that is turned into 100 C steam
Q=(20g)(540 cal/g)=10,800 cal

I hope this helps you.

What does it mean to say that a wave is cyclic, or periodic, disturbance?

Zina [86]

Answer:

Wave is a disturbance or energy that propagate through medium from one point to other point

So basically it is a flowing energy that flows into the medium and hence medium particles start oscillating about their mean position to and fro.

This motion of medium particles or this to and fro motion is about their mean position and this will always be cyclic or periodic motion

This means the disturbance or energy continuously flow through the medium such that it will change the position of medium particle and this will be cyclic in order

For an example

y(x,t) = Asin(kx - ωt + φ)

So here above equation of wave is a travelling wave in which displacement of medium particle from its mean position is given by "y"

Now we can see that this disturbance depends upon the sine function and it will repeat its same position after every 2 pi time interval as it is cyclic function for this value

Due to this phenomenon of repetition of its same position we can say that it is disturbance of wave is cyclic.

Consider the above unbalanced equation. What volume of CO2 is produced at 270. mm Hg and 38.5°C when 0.820 g of C4H8 reacts with

irinina [24]

Answer:

The volume of CO2 is 4.20 L

Explanation:

Step 1: Data given

Pressure = 270 mm Hg = 260 /760 = 0.355263 atm

Temperature : 38.5 °C = 311.65 K

Mass of C4H8 = 0.820 grams

Step 2: The balanced equation

C4H8 + 6O2 → 4CO2 + 4H2O

Step 3: Calculate moles C4H8

Moles C4H8 = mass C4H8 / molar mass C4H8

Moles C4H8 = 0.820 grams / 56.11 g/mol

Moles C4H8 = 0.0146 moles

Step 4: Caalculate moles CO2

For 1 mol C4H8 we need 6 moles O2 to produce 4 moles CO2 and 4 moles H2O

For 0.0146 moles we'll have 4*0.0146 = 0.0584 moles CO2

Step 6: Calculate Volume CO2

p*V = n*R*T

V = (n*R*T) /p

⇒ with V = the volume of CO2 = TO BE DETERMINED

⇒ with n = the moles of CO2 = 0.0584 moles

⇒ with R = the gas constant = 0.08206 L*atm / mol*K

⇒ with T = The temperature = 311.65 K

⇒ with p = the pressure = 0.355263 atm

V = (0.0584 * 0.08206 * 311.65) / 0.355263

V = 4.20 L

The volume of CO2 is 4.20 L
