Answer:
Find the explanation below.
Explanation:
It would make sense for the United States to use SI units in everyday life because most calculations they do, in daily activities such as business and science, affect people in other parts of the world. For example, a United States writer who writes about weight in pounds(lb) and ounce(oz) might not be easily understood by a reader in many other countries of the world. This is because the reader might not be able to convert the measurement using the standards of the SI units where weight is measured in kilograms(kg).
The international system of units is the upgraded system of measurement from the metric system and it is used by almost all the countries of the world except three countries of which the United States is included.
Answer:
The energy of the photon is 1.718×10−26J.
Explanation:
The energy of the photon is
1.718 × 10 − 26J. You use the formula E =, where h is Planck's Constant,c is the speed of light, and λ is the wavelength of the photon.
E== = 1.718×10−26J.
Zn(s) +2 HCl(aq) ---> ZnCl2(aq) +H2(g) (products are Zinc chloride and hydrogen gas)
Due to its small size, lithium has a high melting and boiling point.
<h3>
Why does lithium have high melting and boiling point explain?</h3>
With only one valence electron to contribute to the metallic lattice, lithium and potassium are both alkali metals. We could infer that the metallic bonding is less strong between the electron cloud and the larger potassium cation than it is in the lithium structure. This means that because lithium creates a smaller cation, the electrostatic force in this situation should be greater also Lithium has high ionization energy and a high melting and boiling point because of its small size. As a result, its crystal structure has an extremely high binding energy.
<h3>
Alkali metals</h3>
The chemical elements lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs), and francium make up the alkali metals (Fr). They make up group 1, which is located in the s-block of the periodic table, along with hydrogen.
