how many carbon dioxide molecules are produced if 8.45 x 1023 of water molecules of water are produced

Answers

Answer 1

The given question is incomplete. The complete question is:

Determine how many carbon dioxide molecules are produced if molecules of water are produced

[tex]C_2H_6(g)+O_2 (g)\rightarrow CO2(g)+H_2O(g)[/tex]

Answer: [tex]5.60\times 10^{23}[/tex] molecules of carbon dioxide are produced

Explanation:

The balanced chemical equation is:

[tex]2C_2H_6(g)+7O_2 (g)\rightarrow 4CO2(g)+6H_2O(g)[/tex]

[tex]\text{Moles of water}=\frac{\text{given molecules}}{\text{Avogadros number}}=\frac{8.45\times 10^{23}}{6.023\\times 10^{23}}=1.40moles[/tex]

Accoding to stoichiometry:

6 moles of water are produced along with = 4 moles of carbon dioxide

Thus 1.40 moles of water are produced along with = [tex]\frac{4}{6}\times 1.40=0.93[/tex] moles of carbon dioxide

Molecules of carbon dioxide = [tex]moles\times {\text {Avogadros number}}=0.93\times 6.023\times 10^{23}=5.60\times 10^{23}[/tex]

1. If you have 5g of pennies how many dozen pennies do you have?

Answers

Answer:

15.69 dozen

Explanation:

Mass of penny = 5 g

Dozens of penny =..?

Next, we shall convert 5 g to gross. This can be obtained as follow:

3824 g = 1000 gross

Therefore,

5 g = 5 g × 1000 gross / 3824 g

5 g = 1.3075 gross

Thus, 5 g is equivalent to 1.3075 gross.

Finally, we convert 1.3075 gross to dozen. This can be obtained as follow:

1 gross = 12 dozen

Therefore,

1.3075 gross = 1.3075 gross × 12 dozen / 1 gross

1.3075 gross = 15.69 dozen

Thus, 5 g of penny is equivalent to 15.69 dozen

B. butylcyclopentane
C. propylcyclohexane

Answers

Answer:

The answer for this question is A. butylcyclohexane

Explanation:

Choose letter A

You welcome have a nice day.

Name of the given compound is butyl cyclohexane.

What are cyclo alkanes?

Cyclo alkanes are those organic compounds in which alkanes are present in the cyclic form.

In the nomenclature of cyclo alkane, name of the substitute is put before the name of the main ring. In the given structure number of carbons in ring is 6 so that given cycloalkane is cyclohexane and butyl group is attached as substitute. So name of the given compound is butyl cyclohexane.

Butyl cyclopentane is wrong because 6 carbons are present in ring.Propylcyclohexane is also wrong because 4 carbons are attached in the ring.

Hence name of the compound is butyl cyclohexane.

If combining cation A with a +3 charge and anion X with a -3 charge, how would we write the compound?
O AX
O A3X3
O 3AX

Answers

Answer: it’s not A3X3

Explanation:

1. AX

For binary ionic compounds (ionic compounds that contain only two types of elements), the compounds are named by writing the name of the cation first followed by the name of the anion.If a cation A carries +3 charge and an anion X carries -3 charge, the compound so formed is AX. Since the charges gets cancelled out.For example: consider aluminum phosphate, aluminum carries +3 charge and phosphate carries -3 charge, the molecular formula for the compound will be AlPO₄.

A balloon occupies 175 cm at 25.0 C. What volume will it occupy at 42.5 °C?

Answers

175 cm³ instead of 175 cm.

Answer:

297.5 cm³

Explanation:

From the question;

Initial volume; V1 = 175 cm³

Initial temperature; T1 = 25°C

Final temperature; T2 = 42.5°C

From Charles law we can find the volume V2 from the equation;

V1/T1 = V2/T2

Making V2 the subject gives;

V2 = V1 × T2/T1

V2 = (175 × 42.5)/25

V2 = 297.5 cm³

A 2.00 g sample of ammonia (NH3) reacts with 4.00 g of oxygen (O2) according to the equation 4NH3+5O2→4NO+6H2O. How much excess reactant remains after the reaction has stopped ( knowing that NH3 is the excess reactant )?

Answers

Answer:

0.017 moles of ammonia remains after the reaction is stopped.

Explanation:

The reaction is:

4NH₃  +  5O₂  →  4NO  +  6H₂O

The first step is to convert the mass to moles, of each reactant:

2 g .  1mol/ 17g = 0.117 moles of NH₃

4 g . 1mol /32g = 0.125 moles of O₂

Ammonia, states the question, is the excess reactant so we can confirm it,

5 moles of oxygen need 4 moles of ammonia to react (by stoichiometry)

Then, 0.125 moles of oxygen may react to (0.125 . 4) / 5 = 0.1 moles

As we have 0.117 moles of ammonia and we need 0.1 moles.

(0.117 - 0.1) = 0.017 moles remains after the reaction is completed.

If we convert the moles to mass we have:

0.017 mol . 17 g /1mol = 0.289 g

Measurements show that unknown compound X has the following composition:
element mass %
carbon 74.8%
hydrogen 25.1%
Write the empirical chemical formula of X. please help

Answers

X is carbon and Jess

the empirical chemical formula of X is CH4

Explanation:Step 1: Imagine you have a sample of compound weighing exactly . Multiply the mass of this sample by the mass percents to find the mass of each element in the sample

Step 2: Divide the mass of each element by the element's molar mass to find the moles of each element in the sample. Remember to round your answers to the correct number of significant digits.  

Step 3: Divide the moles of each element by the the smallest number of moles of any element to find the mole ratio of elements in the sample.  

Step 4: Multiply the mole ratio by the smallest whole number that changes it into a whole number ratio to find the atom ratio of elements in the sample.

Note that the result of each multiplication must equal a whole number only within measurement uncertainty.  

The measurement uncertainty in this calculation comes from the measurement uncertainty of the mass percents given in the question. The mass percents each have significant digits. That means each mass percent has some measurement uncertainty in the third significant digit, and only the first two significant digits can be considered completely reliable.  

In Step 1 you multiplied each mass percent by something with zero uncertainty (the exactly you assumed your sample weighed), in Step 2 you divided by a measurement with more than significant digits (the molar mass of the elements), and in Step 3 you divided by a measurement with the same number of significant digits (the least number of moles of any element in the compound). None of these steps added to the measurement uncertainty of your calculation.  

Therefore, the measurement uncertainty in the final result of all your calculations is determined by the measurement uncertainty in the original mass percents and will be in the third significant digit. That means the result of each of the final multiplication steps must equal a whole number only to within the first two significant digits.  

The whole numbers in the last column of the table are and .

How many grams are in 8.50 e 23 formula units of NaCl?
a)82.5 g
b)8.25 g
c)85.0 g
d)91.5 g

Answers

Answer:

a)82.5 g

Explanation:

To solve this problem we will use Avogadro's number, which states the number of formula units per mole.

8.50x10²³formula units ÷ 6.023x10²³ formula units/mol = 1.41 mol

Then we convert 1.41 moles of NaCl to grams, using its molar mass:

1.41 mol NaCl * 58.44 g/mol = 82.4 g

What is an atom ?

Every atom is made up of a nucleus and one or more electrons that are attached to the nucleus. One or more protons and a number of neutrons make up the nucleus. Only the most common type of hydrogen is neutron-free. Every solid, liquid, gas, and plasma is made up of atoms that are either neutral or ionized.

But when it comes to the word atom, we must go back to 400 B.C. Greece. And Democritus, a brilliant philosopher, proposed the Greek word atomos, which means uncuttable.
