Gaseous ethane CH3CH3 will react with gaseous oxygen O2 to produce gaseous carbon dioxide CO2 and gaseous water H2O. Suppose 0.6
yulyashka [42]

Answer:

1.8 g

Explanation:

Step 1: Write the balanced equation

CH₃CH₃(g) + 3.5 O₂(g) ⇒ 2 CO₂(g) + 3 H₂O(g)

Step 2: Determine the limiting reactant

The theoretical mass ratio of CH₃CH₃ to O₂ is 30.06:112.0 = 0.2684:1.

The experimental mass ratio of CH₃CH₃ to O₂ is 0.60:3.52 = 0.17:1.

Thus, the limiting reactant is CH₃CH₃

Step 3: Calculate the mass of CO₂ produced

The theoretical mass ratio of CH₃CH₃ to O₂ is 30.06:88.02.

0.60 g CH₃CH₃ × 88.02 g CO₂/30.06 g CH₃CH₃ = 1.8 g

What is the mass of sodium (Na) in 50 grams of table salt (NaCl)? Show your work.
beks73 [17]

Answer:

The amount of sodium in this sample = 32.4 grams

Explanation:

Mass of Sodium = 23 g/mol

Mass of Chlorine = 35.5 g/mol

Mass of NaCl = 35.5 g/mol

Fraction of Na in NaCl = \frac{23}{35.5}

                                      =0.648

We are given a sample of 50 grams of sodium chloride.

The amount of sodium in this sample = Amount of sodium in 1 gram sample \times weight of sample

The amount of sodium in this sample = 0.648 \times 50

The amount of sodium in this sample = 32.4 grams

As you add electrons to an energy level, without adding more protons are there more or less repulsive
Dmitry_Shevchenko [17]

Answer:

There will be more repulsive force between the electrons.

Explanation:

Electrons contain negative charge.As a result the electron will repulse another adjacent negatively charged electron.

   According to the given question addition of electrons to en energy level without adding more protons will increase the overall negative charge in the the energy level in which the electrons are added.

  This ultimately leads to generate more repulsive force between the electrons.
