Answer:
Crystalline solids, or crystals, have distinctive internal structures that in turn lead to distinctive flat surfaces, or faces. The faces intersect at angles that are characteristic of the substance. When exposed to x-rays, each structure also produces a distinctive pattern that can be used to identify the material.
Explanation:
Potassium outermost electron occupy "4s" orbital
Answer:
26.5 g
Explanation:
First we convert 100.0 mL to L:
- 100.0 mL / 1000 = 0.100 L
Now we <u>calculate how many moles of sodium carbonate are needed</u>, using the <em>definition of molarity</em>:
- Molarity = moles / liters
- moles = molarity * liters
- 2.5 M * 0.100 L = 0.25 mol
Finally we <u>convert 0.25 moles of sodium carbonate into grams</u>, using its <em>molar mass</em>:
- 0.25 mol * 106 g/mol = 26.5 g
An electrochemical process involves any process that has to do with the transfer of elecrons.
<h3>What is an elecrochemical process?</h3>
An electrochemical process involves any process that has to do with the transfer of elecrons. These process include redo reactionand electron transport chains.
It is a true statement that the actiivity series helps to detect the products in a reaction because a metal that is lower in the series is always displaced by a metal that is higher in the series.
