In lab you reacted 60 grams of propane (C3H8) with 13 grams of oxygen gas (O2). Your

reaction made 63 grams of water (H2O). The reaction is shown below:

How much carbon dioxide (CO2) is released into the air?

C3H8 + 5O2 ------> 3CO2 + 4H2O

10 g

73 g

120 g

1368

Answers

Answer:

120g

Explanation:

Based on the reaction, when 1 mole of propane and 5 moles of oxygen react, 3 moles of CO2 and 4 moles of H2O are produced. The ratio of production is 3 moles of CO2 per 4 moles of H2O.

Thus, we need to convert mass of water to moles using its molar mass:

Moles H2O (Molar mass: 18g/mol):

63g H2O * (1mol / 18g) = 3.5 moles H2O

Converting to moles of CO2:

3.5 moles H2O * (3 moles CO2 / 4 moles H2O) = 2.625 moles CO2

Mass CO2 (Molar mass: 44g/mol):

2.625 moles CO2 * (44g / mol) = 115.5g of CO2 are released

120g

calculate the ph of a solution whose(oh^-) is 4.583*10^-5 mole dm cube (pkw=14)​

Answers

pH of solution = 9.661

Further explanation

pH is the degree of acidity of a solution that depends on the concentration of H⁺ ions. The greater the value the more acidic the solution and the smaller the pH.

pH = - log [H⁺]

So that the two quantities between pH and [H⁺] are inversely proportional because they are associated with negative values.

pOH=-log[OH⁻]

[tex]\tt pOH=-log[4.583\times 10^{-5}]\\\\pOH=5-log~4.583=4.339[/tex]

pH+pOH=pKw

[tex]\tt pH=14-4.339\\\\pH=9.661[/tex]

When propane is reacted in the presence of oxygen gas, the products of this combustion reaction are: A. CO + H2O B. CO2 + H2O C. C2H4 + H2O D. CH4 + H2O

Answers

Answer:

B. CO2 + H2O

Explanation:

Propane is an hydrocarbon as it contains only v=carbon and hydrogen atoms.

Whenever an hydrocarbon reacts with oxygen or undergoes a combustion reaction, two products are always formed only,

These two products are;

Carbon dioxide (CO2) and water (H2O)

This means the correct option is option B.

What is the frequency of a photon with an energy of 3.38 x 10-19 J?​

Hey There!_____________________________________Answer:

[tex]\huge\boxed{5.1x[tex]10^{14}[/tex]Hz}[/tex]

_____________________________________DATA:

E = [tex]3.38 x 10^{-19}[/tex]

h = [tex]6.625x10^{-34}[/tex]

f = ?

_____________________________________SOLUTION:

Energy of Photon is given by,

                                   

                                   E = hf

Rearrange the equation,

                             

                                    f = [tex]\frac{E}{h}[/tex]

where,

           E = energy

           h = planck's constant

           f = frequency

------------------------------------------------------------------------------------------------------------

Substitute the variable in the equation,

 

                                 f = [tex]\frac{3.38x10^{-19}}{6.62x10^{-34}}[/tex]

Simplify the equation,

How many grams are equal to 0.11 mole of copper(I) chromate?

Answers

Mass of Copper(I) chromate( CuCrO₄) = 19.75 g

Further explanation

The mole is the number of particles contained in a substance

1 mol = 6.02.10²³

Moles can also be determined from the amount of substance mass and its molar mass

[tex]\tt \large{\boxed{\bold{mol=\dfrac{m(mass)}{MW(molecular~weight)}}}[/tex]

0.11 mole of Copper(I) chromate( CuCrO₄) ⇒ MW=179.54 g/mol, so mass :

A state property X has a value 89.6 units. It undergoes the following changes, first increase by
3.6 units, then increase by another 18.7 units, then decrease by 12.2 units and finally attains a
value of 85.5 units The value for this series of change is A) 14.2 units
B) -4.1 units C) 108.3 units
D) uncertain​

Answers

Answer:

B) -4.1 units

Explanation:

According to this question, a state property X has a value 89.6 units. It undergoes the certain changes as follows:

- first increase by 3.6 units

- then increase by another 18.7 units

- then decrease by 12.2 units

- and finally attains a value of 85.5 units

This can be mathematically represented by 89.6 - {3.6 + 18.7 - 12.2 - x) = 85.5

To get x, we say;

89.6 + 3.6 = 93.2

93.2 + 18.7 = 111.9

111.9 - 12.2 = 99.7

99.7 - 85.5 = 14.2units.

The changes that occured is represented as follows:

= (3.6 + 18.7) - (12.2 + 14.2)

= 22.3 - 26.4

= -4.1 units

Answers

Answer:

5 moles

Explanation:

Given data:

Number of moles of HCl = 5 mol

Number of moles of H₂O produced = ?

Solution:

Chemical equation:

HCl + NaOH     →   NaCl + H₂O

Now we will compare the moles of HCl with H₂O.

                          HCl            :           H₂O

                             1               :             1

                             5               :            5

5 moles of water will be produced.
