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.
Answer options
|
|
A.18.0 g because mass is created for the final product. |
|
|
B. 18.0 because the mass of the products must equal the mass of the reactants |
|
|
C. 76.5 g because mass cannot be created or destroyed |
|
|
D. 76.5 g because the mass of the final product must equal the reactants. |
![**Chemical Reaction and Data Analysis**
**Reaction:**
\[ \text{HCl (aq) + NaOH (aq) } \rightarrow \text{ NaCl (s) + H}_2\text{O (l)} \]
**Data Table:**
| Substance | Mass |
|------------|--------------|
| Mass of HCl| 36.5 g |
| Mass of NaOH| 40.0 g |
| Mass of NaCl| 58.5 g |
| Mass of H₂O | ?? |
**Problem Question:**
What mass of water is expected to be produced in the reaction above?
**Explanation of Table:**
The table lists the masses of hydrochloric acid (HCl), sodium hydroxide (NaOH), sodium chloride (NaCl), and the unknown mass of water (H₂O) that is produced in the reaction. Based on the law of conservation of mass, the total mass of reactants (HCl and NaOH) must equal the total mass of products (NaCl and H₂O).
**Calculation:**
- Total mass of reactants = Mass of HCl + Mass of NaOH = 36.5 g + 40.0 g = 76.5 g
- Total mass of products = Mass of NaCl + Mass of H₂O = 58.5 g + Mass of H₂O
To find the mass of H₂O, set the total mass of reactants equal to the total mass of products:
\[ 76.5 \text{ g} = 58.5 \text{ g} + \text{Mass of H}_2\text{O} \]
\[ \text{Mass of H}_2\text{O} = 76.5 \text{ g} - 58.5 \text{ g} = 18.0 \text{ g} \]
Therefore, the expected mass of water produced in the reaction is 18.0 grams.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fc1357887-becf-4289-b67d-2b8f988a0b81%2F1479a824-e6f6-4bec-aeb6-eef8ed09c1f4%2Filv4eu7_processed.png&w=3840&q=75)
