False, solar eclipses happen when the moon moves between the Sun and the Earth, blocking the Sun's rays and casting a shadow on Earth. It happens about once every 18 months (on average)
the molecules in a liquid are loosely arranged, and are arranged randomly
The answer is actually Water Splitting! Hope this works:D
Since there is no sample, let us assume 100 g of the solution:
(22.2% of 100 g) / (46.0254 g HCOOH/mol) = 0.48234 mol HCOOH
(100 g - 22.2 g) = 77.8 g = 0.0778 kg water
(0.48234 mol HCOOH) / (0.0778 kg) = 6.1997 mol/kg = 6.20 m HCOOH
(77.8 g H2O) / (18.01532 g H2O/mol) = 4.3185 mol H2O
(0.48234 mol HCOOH) / (0.48234 mol + 4.3185 mol) = 0.100 [the mole fraction of HCOOH]
Hydrochloric acid is very corrosive. Handling it should be properly taken cared off. Personal protective equipment should be worn at all times when using this substance. PPE includes gloves specific for the substance used, goggles, closed flat shoes and laboratory gown. The same should be done for handling silver nitrate.<span />
