Electrons are electrochemically negatively charged particles that move random around the nucleus. They have a relatively small mass compared to Protons and Neutrons. They are found in electron clouds that surround the nucleus and their movement and properties provide for the bonding characteristics of each atom.
By taking hydrogen ions, certain bases directly lower the H+ than OH- concentration. Other bases break down to create hydroxide ions, which indirectly lowers the H+ concentration.
<h3>
What is the difference between acid and base?</h3>
H+ ion concentration is raised by an acid. A base is a chemical that, in an aqueous solution, produces hydroxide (OH-) ions, gives electrons, and receives protons. A donor of protons is an acid. A proton can enter a base. When dissolved in water, an acidic chemical compound produces a solution that has more H+ ion activity than clean water. A base is an aqueous material that releases hydroxide (OH-) ions, receives protons, or contributes electrons. A donor of protons is an acid. A base is a proton acceptor.

D) carbon dioxide is the answer to your question
Answer:
Explanation:
1. Calculate the mass of each reactant gas in the mixture
<u>a) CH₄</u>
- 28.6% of 289g
- 0.286 × 289g = 82.654g
<u>b) C₃H₈</u>
- 71.4% of 289g
- 0.714 289g = 206.346g
2. Calculate the mass of CO₂ produced by each gas in the mixture
<u>a) CH₄</u>
i) Balanced chemical equation:
- CH₄(g) + 2O₂(g) → CO₂(g) + 2H₂O(g)
ii) Number of moles of CH₄:
- number of moles = mass in grams / molar mass
- molar mass of CH₄ = 16.04g/mol
- number of moles = 82.654g / 16.04 g/mol = 5.153 mol
iii) Number of moles of CO₂
- From the balanced chemical equation, the mole ratio is 1 mol CH₄ : 1 mol CO₂.
- Hence, 5.153 mol of CO₂ are produced
iv) Convert the number of moles to mass
- mass = number of moles × molar mass
- molar mass of CO₂ = 44.01g/mol
- mass = 5.153 mol × 44.01g/mol = 226.8 g
<u />
<u>b) C₃H₈</u>
i) Balanced chemical equation:
- C₃H₈(g) + 5O₂(g) → 3CO₂(g) + 4H₂O(g)
ii) Number of moles of C₃H₈:
- number of moles = mass in grams / molar mass
- molar mass of C₃H₈ = 44.1g/mol
- number of moles = 206.346g / 44.1 g/mol = 4.679 mol
iii) Number of moles of CO₂
- From the balanced chemical equation, the mole ratio is 1 mol C₃H₈ : 1 mol CO₂.
- Hence, 4.679 mol of CO₂ are produced
iv) Convert the number of moles to mass
- mass = number of moles × molar mass
- molar mass of CO₂ = 44.01g/mol
- mass = 4.679 mol × 44.01g/mol = 205.9 g
3. Total mass of CO₂
Add the two values found above:
Round to 3 significant figures: 433g.
