The answer for the first question is A. Iced Tea and C. Orange Juice. The answer for the second question is A. Heterogeneous mixture
A homogeneous mixture is a combination of 2 or more substances wherein its concentration is evenly distributed throughout the mixture. This means that you cannot identify the different components or properties of the mixture. A heterogeneous mixture, on the other hand, is a combination of 2 or more substances wherein its components are unevenly distributed. This means that its components can visibly be identified from each other.
Answer: Volume required is 0.115 L or 115 ml
Explanation:
moles of =
The balanced chemical equation is:
1 mole of requires = 1 mole of HCl
Thus 0.015 mol of requires = mole of HCl
Molarity of a solution is defined as the number of moles of solute dissolved per liter of the solution.
where,
n = moles of solute
= volume of solution in L
Thus volume required is 0.115 l or 115 ml

Answer:
The answer to your question is below
Explanation:
Ions are atoms that are electrically charged. There are two kinds of ions
- Cations are ions with a positive charge.
- Anions are ions with a negative charge.
Sodium forms cations because it loses one electron and I can bound to anions like halogens.
Then, the paragraph will be:
"If the sodium ion has a + charge after ionization, then it will interact with a Chlorine ion which has a - charge".
HCl is a strong base therefore it completely dissociates to H⁺ and Cl⁻ ions.
To calculate pH we need to know [H⁺]
number of HCl moles in 50.0 mL - 0.200 M /1000 mL/L x 50.0 mL = 0.01 mol
concentration of HCl - 0.01 mol/0.1 L = 0.1 M
[HCl] = [H⁺] due to complete dissociation
pH = -log [H⁺]
pH = -log (0.1 M)
pH = 1
pH of the solution is 1
