States of Matter
The substance that constitutes everything in the universe is known as matter. Matter comprises atoms which in turn are composed of electrons, protons, and neutrons. Different atoms combine together to give rise to molecules that act as a foundation for all kinds of substances. There are five states of matter based on their energies of attraction, namely solid, liquid, gases, plasma, and BEC (Bose-Einstein condensates).
Chemical Reactions and Equations
When a chemical species is transformed into another chemical species it is said to have undergone a chemical reaction. It consists of breaking existing bonds and forming new bonds by changing the position of electrons. These reactions are best explained using a chemical equation.
Question
![# Calculating Molecular Weight of Sulfur Tetrafluoride (SF₄)
To determine the molecular weight of the compound sulfur tetrafluoride (SF₄), complete the table below. This involves summing the products of the atomic weights and the number of atoms of each element present in the molecule.
## Table for Calculating Molecular Weight:
| Atom | Atomic Weight | \# Atoms | Weight in Compound |
|------|---------------|----------|--------------------|
| **S** | \_\_\_\_\_\_ amu/atom | \_\_\_\_ atoms | \_\_\_\_\_\_ amu |
| **F** | \_\_\_\_\_\_ amu/atom | \_\_\_\_ atoms | \_\_\_\_\_\_ amu |
## Instructions:
1. **Identify Atomic Weights:**
- Sulfur (S)
- Fluorine (F)
2. **Determine Number of Atoms:**
- The molecular formula SF₄ indicates there is 1 sulfur atom and 4 fluorine atoms.
3. **Calculate the Weight in Compound:**
- Multiply the atomic weight of each element by the number of atoms present and fill in the respective boxes.
4. **Summing the Weights:**
- Add the weights to find the total molecular weight of sulfur tetrafluoride.
\[
\text {Molecular weight sulfur tetrafluoride} = \_\_\_\_\_\_ \text { amu}
\]
Ensure that all atomic weights are in atomic mass units (amu). By completing the table and following these steps, you will successfully calculate the molecular weight of SF₄.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F5c33053e-aa43-49cf-b2bb-78272e2ba689%2F559cbdec-530e-48a7-b0af-8befcf5a57bc%2Ftra5t2n.png&w=3840&q=75)
