What challenges would you encounter with the titration if you had used apple cider vinegar or balsamic vinegar as the analyte in

stead of white vinegar?
Chemistry

Vika [28.1K]3 years ago
3 0

Explanation:

Apple cider vinegar or balsamic vinegar might contain various synthetics which might  interact with or nullified the findings, whereas white vinegar comprises of acidic acid only. In fact, apple cider vinegar and balsamic vinegar are deep in appearance this would make it very difficult to determine the color. This is why it is preferable to use white vinegar in the Titration process.

Which of the following will have a larger radius than zinc ? Gallium (Ga) Magnesium (Mg) Aluminum (Al) Strontium (St)
oksian1 [2.3K]

Answer:

Strontium (St)

Explanation:

The atom that will have a larger radius than zinc is strontium, Sr.

Atomic radius is defined as the half of the inter-nuclear distance between two covalently bonded atoms of non-metallic elements or half of the distance between two nuclei in the solid state of metals.

  • Across the period atomic radii decreases progressively due to the increase in nuclear charge.
  • Down a group atomic radii increase progressively due to the successive shells of electrons being added.
  • Since strontium satisfies the criteria, it has the larger atomic radius.

(a) 4.12 x 10^15 atoms U
DochEvi [55]

Answer:

1.63ₓ10⁻⁶ g of U

139.03 g of H

0.385 g of O

141.8 g of Pb

Explanation:

In first place, we need to convert the number of atoms to moles, as we know that 1 mol of anything occupies 6.02×10²³ particles

Therefore:

4.12×10¹⁵ atoms of U . 1 mol / 6.02×10²³ atoms = 6.84×10⁻⁹ moles of U

8.37×10²⁵ atoms of H . 1 mol /6.02×10²³ atoms = 139.03 moles of H

1.45×10²² atoms of O . 1 mol /6.02×10²³ atoms = 0.0241 moles of O

4.12×10²³ atoms of Pb . 1 mol /6.02×10²³ atoms = 0.684 moles of Pb

Moles . Molar mass = Mass (g)

6.84×10⁻⁹ moles of U . 238.03 g/mol = 1.63ₓ10⁻⁶ g of U

139.03 moles of H . 1 g/mol = 139.03 g of H

0.0241 moles of O . 16 g/mol = 0.385 g of O

0.684 moles of Pb . 207.2 g/mol = 141.8 g of Pb

julia-pushkina [17]

A Biochemist is a type of chemist understands the structure of living systems and, in turn, their functions and ways to control them.

<h3>What is the chemistry of living systems called?</h3>

The chemistry of living system is known as Biochemistry.

Biochemistry is a study of the chemical changes that occur in living organisms.

Scientists that study biochemistry are called Biochemists.

Biochemistry studies the structure and function of biological molecules such as carbohydrates, lipids, proteins, e.t.c., as well the chemical reaction they undergo.

Biochemistry also studies the energy changes that occur in living systems.

In conclusion, the chemistry of living systems is called Biochemistry.
