Answer:
The correct answer is "They can be separated by physical processes"
Explanation:
The definition of Mixtures is <em>the blending of two or more dissimilar substances</em>.
Mixtures can be divided into those that are homogeneous or heterogeneous meaning that they can be distributed evenly or can't be distributed evenly.
Answer:
By sharing their valence electrons, both hydrogen atoms now have two electrons in their respective valence shells. Because each valence shell is now filled, this arrangement is more stable than when the two atoms are separate.
Explanation:
Answer:
C
Explanation:
Calcium is an element with a total of 20 electrons.
It has 4 shells with a configuration of:
2, 8, 8, 2
Option C is the most similar to calcium but the number of shells is not complete.
It still requires two more shells with 8 and two electrons respectively.
That number, also known as the frequency, will be larger for a short-wavelength wave than for a long-wavelength wave. The equation<span> that relates wavelength and frequency for electromagnetic waves is: λν=c where </span>λ<span> is the wavelength, ν is the frequency and c is the speed of light.</span>
Answer:
<u></u>
Explanation:
The current temperature and pressure at <em>STP </em>(Standard Temperature and Pressure) stated by IUPAC are:
- Temperature: 273.15 K (0 °C)
- Pressure: 10⁵ Pa ≈ 0.9869 atm
Using the <em>ideal gas </em>equation, pV = nRT, and the Avogadro constant, you can find the<em> volume occupied by 5.80 × 10²⁰ molecules.</em>
