Answer:
an ion is an element that carries either positive or negative charge. the example are cation which has a positive charge e.g H+ and anion which had a negative charge eg Cl-.
Answer:
(Magnox, AGR, PWR, BWR, CANDU and RBMK) have emerged as the designs used to produce commercial electricity around the world. A further reactor type, the so-called fast reactor, has been developed to full-scale demonstration stage.
Explanation:
Answer:
The answer to your question is 0.6 M
Explanation:
Data
Molarity = ?
Volume = 450 ml
mass of NaCl = 15 g
Process
1.- Calculate the molar mass of NaCl
NaCl = 23 + 35.5 = 58.5 g
2.- Calculate the number of moles of NaCl
58.5 g of NaCl ------------ 1mol
15 g of NaCl ------------ x
x = (15 x 1)/58.5
x = 0.26 moles
3.- Calculate the molarity
Molarity = moles/volume
-Substitutiion
Molarity = 0.26/0.45l
-Result
Molarity = 0.6 M
These nutrient classes can be divided into macronutrients (nutrients required in large quantities) and micronutrients (nutrients required in tiny quantities). Carbohydrates, proteins, lipids, fiber, and water are macronutrients, whereas vitamins and minerals are micronutrients.
