Answer: SOLID WATER(ICE) IS LESS DENSE THAN LIQUID WATER

Explanation:Water molecules are bonded together by Hydrogen bonds, Hydrogen bonds are intermolecular forces binding the molecules of Oxygen with that of Hydrogen. When in an ICE state,the solid form of water will float on the liquid form of water, because the orientation of Hydrogen bonds pushes or makes the Ice molecules to stay far apart from each making it less Dense than liquid water.

In the reaction of silver nitrate with sodium chloride, how many grams of silver chloride will be produced from 100. g of silver
pantera1 [17]

Answer:

The mass in grams of silver chloride, AgCl produced is 84.37 grams

Explanation:

The chemical equation for the reaction is given as follows;

AgNO₃ + NaCl   →  AgCl + NaNO₃

The mass of silver nitrate, AgNO₃, in the reaction = 100.0 g

Therefore, 1 Mole of AgNO₃ produces 1 mole of AgCl,

The molar mass of silver nitrate, AgNO₃ = 169.87 g/mol

The number of moles of silver nitrate, AgNO₃, in the reaction = 100/169.87 moles

The number of moles of silver nitrate, AgNO₃, in the reaction ≈ 0.59 moles

Since 1 mole of AgNO₃ produces 1 mole of AgCl, 0.59 moles of AgNO₃ produces 0.59 moles of AgCl

The number of moles of silver chloride, AgCl produced = 0.59 moles

The molar mass of silver chloride, AgCl = 143.32 g/mol

Therefore;

The mass of silver chloride, AgCl produced = The number of moles of silver chloride, AgCl produced × The molar mass of silver chloride, AgCl

Which gives;

The mass of silver chloride, AgCl produced = 143.32 g/mol × 0.59 moles = 84.37 g

The mass of silver chloride, AgCl produced = 84.37 g.

Solar, wind, and water power are renewable resources and can replace our dependence on fossil fuels. They each have their own dr
Vesna [10]
Solar- the sun is not always shining, for example at night you can't get any energy from the sun
Wind-it's not always windy
Water- there can be drought
Really the main issue of all three of these is that they are not always available
