What is the mass of an atom that has 9 protons, 11 neutrons, and 10 electrons
Anastaziya [24]

Answer: By looking at the periodic table, you will see that Fluorine has 9 protons. Since the number of electrons equal the number of protons, Fluorine has 9 electrons as well. Meanwhile, it's mass number of 19, minus 10 neutrons, gives you 9 protons or electrons. Hence, the atom would be Fluorine.

How many sucrose molecules are in 3.0 moles of sucrose scientific
DiKsa [7]
Answer:
             1.80 × 10²⁴ Molecules of Sucrose

Solution:

Number of Moles and Number of Particles (molecules in given case) are related to each other as,

                  Moles  =  Number of Molecules ÷ 6.022 × 10²³

Solving for Number of Molecules,

                  Number of Molecules  =  Moles × 6.022 × 10²³

Data Given;
                     Moles  =  3 moles

Putting values in eq,


                 Number of Molecules  =  3 mol × 6.022 × 10²³


                 Number of Molecules  =  1.80 × 10²⁴ Molecules

A sample of a gas in a rigid container has an initial pressure of 1.049 kPa and an initial temperature of 7.39 K. The temperatur
Doss [256]

Answer:- 4.36 kPa

Solution:- At constant volume, the pressure of the gas is directly proportional to the kelvin temperature.

\frac{P_1}{T_1}=\frac{P_2}{T_2}

Where the subscripts 1 and 2 are representing initial and final quantities.

From given data:

P_1 = 1.049 kPa

P_2 = ?

T_1 = 7.39 K

T_2 = 30.70 K

For final pressure, the equation could also be rearranged as:

P_2=\frac{P_1T_2}{T_1}

Let's plug in the values in it:

P_2=\frac{1.049kPa(30.70K)}{7.39K}

P_2 = 4.36 kPa

So, the new pressure of the gas is 4.36 kPa.

2b. 12 grams of C8H18 react with oxygen to produce carbon dioxide and water. How many grams of CO2 are produced?
likoan [24]

Answer:

37.1g are produced

Explanation:

The combustion of C₈H₁₈ is:

C₈H₁₈ + 25/2O₂ → 8CO₂ + 9H₂O

<em>Where 1 mole of C₈H₁₈ produce 8 moles of CO₂</em>

<em />

To find the mass of CO₂ that is produced we need to convert the mass of C₈H₁₈ with molar mass. Then, with the chemical equation, we can find the moles of CO₂ and its mass, as follows:

<em>Moles C₈H₁₈ -Molar mass: 114.2g/mol-</em>

12g C₈H₁₈ * (1mol / 114.2g) = 0.105 moles of C₈H₁₈

<em>Moles CO₂:</em>

As 1 mole of C₈H₁₈ produce 8 moles of CO₂, 0.105 moles of C₈H₁₈ produce:

0.105 moles of C₈H₁₈ * (8moles CO₂ / 1mole C₈H₁₈) = 0.84 moles of CO₂

<em>Mass CO₂ -Molar mass: 44.01g/mol-:</em>

0.84 moles of CO₂ * (44.01g / mol) = 37.0g of CO₂ ≈

<h3>37.1g are produced</h3>
