Ganezh [65]

Answer: The laboratory value of potassium (3.0 mmol / L) is consistent with the client's symptoms of hypokalemia.

Explanation:

Hello!

Let's solve this!

Hypokalemia is a disorder in the body's electrolyte balance, when the decrease in blood potassium (K) ion levels is below 3.5 mmol / L. Potassium losses can occur through the digestive tract: such as vomiting and

diarrhea The most frequent symptoms of potassium loss include: tiredness, muscle weakness and cramping.

In conclusion, the laboratory value of potassium (3.0 mmol / L) is consistent with the client's symptoms of hypokalemia.

<u>Chemistry</u>

<u>Atomic Structure</u>

  • Using Dimensional Analysis
  • Avogadro's Number - 6.022 × 10²³ atoms, molecules, formula units, etc.
<h3>Explanation:</h3>

<u>Step 1: Define</u>

1.50 × 10¹² atoms Pb

<u>Step 2: Identify Conversions</u>

Avogadro's Number

<u>Step 3: Convert</u>

  1. Set up:                                         \displaystyle 1.50 \cdot 10^{12} \ atoms \ Pb(\frac{1 \ mol \ Pb}{6.022 \cdot 10^{23} \ atoms \ Pb})
  2. Multiply:                                                                                                           \displaystyle 2.49087 \cdot 10^{-12} \ moles \ Pb

<u>Step 4: Check</u>

<em>Follow sig fig rules and round. We are given 3 sig figs.</em>

2.49087 × 10⁻¹² moles Pb ≈ 2.49 × 10⁻¹² moles Pb

Explain how electron microscopy and scanning tunneling microscopes have contributed to the understanding of atoms.
Eva8 [605]

Answer:

Electron microscopy and scanning tunneling microscopes contributed to the understanding of atoms in understanding atomic structure.

The electron microscope has magnifications of about 100,000x.

This helped the scientists to have accurate image groupings of the atoms. Scanning tunnel microscope helped scientists to have the images of groups of atoms.
