Answer:
Nitrous oxide, commonly known as laughing gas or nitrous, is a chemical compound, an oxide of nitrogen with the formula N ₂O. At room temperature, it is a colourless non-flammable gas, with a slight metallic scent and taste. At elevated temperatures, nitrous oxide is a powerful oxidiser similar to molecular oxygen.
Explanation:
Answer:
DOUBLE DISPLACEMENT (mutual exachange of ions in aqueous form)
Ca is more reactive than Fe
hence it will displace Fe from ferrous nitrate solution and form Calcium Nitrate and Ferrous Sulphate will be formed
GOOD LUCK WITH THE FUTURE! :)
<u>Answer:</u> The mass percent of water in the hydrated salt is 43.6 %
<u>Explanation:</u>
To calculate the mass for given number of moles, we use the equation:
Moles of water = 8 moles
Molar mass of water = 18 g/mol
Putting values in above equation, we get:
We are given:
Mass of anhydrous salt = 186.181 g
To calculate the mass percentage of water in the hydrated salt, we use the equation:
Mass of hydrated salt = [186.181 + 144]g = 330.181g
Mass of water = 144 g
Putting values in above equation, we get:
Hence, the mass percent of water in the hydrated salt is 43.6 %
