Answer:

Ne

Explanation:

Neon is the 10th element in the periodic table, and it has all of its orbitals filled up with electrons, the electronic configuration of the element that contains 168 electrons will be an electronic configuration that ends up with all of the orbitals filled up, so it would be most similar to the Neon which is a noble gas, meaning that 168th element will also be a noble gas.

When heated, calcium carbonate decomposes according to the equation given below:
Margaret [11]

Answer:

Percent yield = 90.9%

Explanation:

Given data:

Mass of CaCO₃ = 50.0 g

Mass of CO₂ produced = 20.0 g

Percent yield = ?

Solution:

Chemical equation:

CaCO₃ →  CaO + CO₂

Number of moles of CaCO₃:

Number of moles = mass/molar mass

Number of moles = 50.0 g/ 100.1 g/mol

Number of moles = 0.5 mol

Now we will compare the moles of CO₂ with CaCO₃.

                      CaCO₃          :        CO₂

                          1                :           1

                       0.5               :          0.5

Mass of CO₂: Theoretical yield

Mass = number of moles × molar mass

Mass = 0.5 mol × 44 g/mol

Mass = 22 g

Percent yield:

Percent yield = ( actual yield / theoretical yield ) × 100

Percent yield = (20.0 g/ 22.0 g) × 100

Percent yield = 0.909 × 100

Percent yield = 90.9%
