Answer: Option (A) is the correct answer.

Explanation:

The valence electrons are the electrons which are present in the outermost shell of an atom.

A silver atom contains a positive charge as silver is a cation.

In a piece of silver, the silver atoms will be linked together. As it is known that silver is a cation, it will hold a positive charge.

Therefore, it can be concluded that in a piece of silver, the valence electrons will be moving freely between the cations.

1.5mol C3H8 from C3H8+5O2-->3CO2+4H2O .how many grams of carbon dioxide are produced

koban [17]

Answer:

$\large \boxed{\text{200 g CO}_{{2}}}$

Explanation:

We will need a balanced equation with masses, moles, and molar masses, so let’s gather all the information in one place.

Mᵣ: 44.01

C₃H₈ + 5O₂ ⟶ 3CO₂ + 4H₂O

n/mol: 1.5

1. Calculate the moles of CO₂

The molar ratio is 3 mol CO₂:1 mol C₃H₈

$\rm \text{Moles of CO}_{2} = \text{1.5 mol C$_{3}$H}_{8} \times \dfrac{\text{3 mol CO}_{2}}{\text{1 mol C$_{3}$H}_{8}} =\text{4.5 mol CO}_{2}$

2. Calculate the mass of CO₂.

$\text{Mass of CO}_{2} = \text{4.5 mol CO}_{2} \times \dfrac{\text{44.01 g CO}_{2}}{\text{1 mol CO$_{2}$}} = \textbf{200 g CO}_{\mathbf{2}}\\\text{The reaction will form $\large \boxed{\textbf{200 g CO}_{\mathbf{2}}}$}$

Melissa is interested in her family tree and how her family has changed over its many generations. Melissa probably more closely

tresset_1 [31]

Answer: A Confucian

Explanation:

In the year 2005, the Guinness Book of World Records recognized the Confucius genealogical line as the longest family tree in history. They have a record of 86 generations over 2,500 years. Confucius (551 to 479 BCE) is believed to have about 3 million descendants all over the world.

So the interest Melissa has in her family tree and also wanting to know how her family has changed over its many generations probably suggests that Melissa more closely resembles a Confucian.
