Explanation:
The terms ‘sand’ and ‘soil’ are often interchanged and used synonymously with one another. Many people consider them the same, but when scrutinized, they are quite different from each other. First and foremost, sand is a type of soil–so is silt, clay, peat, and loam. These types of soils are generated when rocks break up into their constituent parts and are acted upon by outside forces, such as wind, water, and natural salts. The broad definition of soil refers to the loose layer of earth that covers the surface of the planet. Sand, on the other hand, is defined as loose material that consists of rocks or mineral grains.
Answer:
W.K.T molar mass of Cuso4.5H2O = 159.609 + 90 = ~250. Mass of water of crystallization = 5 * 18 = 90. Percentage = 90/250 * 100= 36%.
It is b no more solute can be dissolved
The mass of NaCl produced is calculated as below
write the reacting equation
that is 2 Na + Cl2 =2 NaCl
by use of mole ratio between Na :NaCl which is 2 :2 t he moles of NaCl is also = 5.50 moles
mass of NaCl= moles x molar mass
=5.50 moles x58.5 g/mol = 321.75 grams
Answer:
The answer is option C; the reaction is at equilibrum
