Perform an on-line search to find real-world uses for the titration process. State what you find below.

aleksandr82 [10.1K]

Answer:

The titration process has quite a few real-world uses, including key roles in the food industry and medical community. The titration process is essentially an analytical technique, as it is used to determine a chemical or physical property of a chemical substance, element, or mixture (such as food). Specifically in the food industry, it is used to allow food manufactuers to determine the quantity of a reactant in a sample. To provide an example, it can be used to find the specific amount of stuff that is usually labeled on the nutrition label, such as sugar, salt, protein, calcium, vitamin C, etc. As for the medical world, pharamcists typically use this process to get the proper mix when compounding medicines. It is used to get the necessary proportions in intravenous drips.

Calculate the number of hydrogen atoms in a 110.0 sample of tetraborane(B4H10) . Be sure your answer has a unit symbol if necess

Contact [7]

Answer:

$1.242 \times 10^{25}\text{ atoms H}$

Explanation:

You must convert the mass of B₄H₁₀ to moles of B₄H₁₀, then to molecules of B₄H₁₀, and finally to atoms of H.

1. Moles of B₄H₁₀

$\text{Moles of B$_{4}$H}_{10} = \text{110.0 g B$_{4}$H}_{10} \times \dfrac{\text{1 mol B$_{4}$H}_{10}}{\text{53.32 g B$_{4}$H}_{10}} = \text{2.063 mol B$_{4}$H}_{10}$

2. Molecules of B₄H₁₀

$\text{No. of molecules} = \text{2.063 mol B$_{4}$H}_{10} \times \dfrac{6.022 \times 10^{23}\text{ molecules B$_{4}$H}_{10}}{\text{1 mol B$_{4}$H}_{10}}\\\\=1.242 \times 10^{24}\text{ molecules B$_{4}$H}_{10}$

3. Atoms of H

$\text{Atoms of H} = 1.242 \times 10^{24}\text{ molecules B$_{4}$H}_{10} \times \dfrac{\text{10 atoms H}}{\text{1 molecule B$_{4}$H}_{10}}\\\\= \mathbf{1.242 \times 10^{25}}\textbf{ atoms H}$

A chemist dissolves 614. mg of pure hydrochloric acid in enough water to make up 400 mL of solution. Calculate the pH of the sol

tatuchka [14]

Answer:

The pH of the solution is 1.38.

Explanation:

Mass of HCl = 614 mg = 0.614 g

Moles of HCl = $\frac{0.614 g}{36.5 g/ mol}=0.01682 mol$

Concentration of HCl :

$Concentration =\frac{Moles}{\text{Volume of solution in L}}$

On adding 0.01682 moles to 400 mL of water that 0.4 L of water.

$[HCl]=\frac{0.01682 mol}{0.4 L}=0.04205 M$

$HCl(s)+H_2O(l)\rightarrow H_3O^+(aq)+Cl^-(aq)$

1 mole of HCl gives 1 mole of hydronium ion and 1 mole of chloride ions in an aqueous solution.

Then 0.04205 mol/L of HCl will give:

$1\times 0.04205 M =0.04205 mol/L$ of hydronium ions.

$[H_3O^+]=0.04205 M$

$pH=-\log [H_3O^+]$

$pH=-\log [0.04205 M]=1.38$

The pH of the solution is 1.38.

How is the water cycle realated to weather patterns and climate? Make sure to put 2 evidences

Setler79 [48]

When there’s water in a department such as a lake, pound or/and ocean, the water tends to evaporated into the air and that’s how/when clouds are created. The same water from those locations are the same water that comes from the rain water, it’s a cycle that creates and takes water
