Answer:
16.7%
Explanation:
40 ml of salt water + 200 ml of solution = 240 ml
40/240 = 4/24 = 1/6=16.7%
The CaCO3 produced if 47.5 moles of NH3 produced is calculated as follows
CaCN2 +3H2O = CaCO3 + 2NH3
by use of mole ratio between CaCO3 to NH3 which is 1:2 the moles of CaCO3 is therefore = 47.5 /2= 23.75 moles
mass of CaCO3 is therefore = moles x molar mass
= 23.75 moles x 100g/mol= 2375 grams which is approximate 2380 grams(answer 6)

Sedimentary rocks are formed when different layers of debris ( usually sand ) are forced together under pressure.
Metamorphic rock forms from other types of rock that have been changed by a combination of high heat and pressure.
Igneous rock forms when Lava/Magma cools down
Answer:
Surface Irrigation. Water is scattered equally throughout the land with the help of gravitational pull and it doesn’t require a machine to take care of it.
Localized Irrigation. Water is scattered throughout the land under low pressure.
Drip Irrigation. In this process of drip irrigation, the water drops fall on the root of every plant that is around the system.
