How many ions of Na+ and C1- will be present in 30g of NaCl? <br> Ans fast plis
ahrayia [7]

3.08*10^23 ions of Na+ and Cl- will be present in 30g of NaCl.

Weight of NaCl is equal to sum of weight of one mole of sodium and one mole of chloride.

Mathematically, it can be represented as -

1 mol (Na) + 1 mol (Cl)

= 23.0+ 35.5

= 58.5 g/mol

In 58.5  gram of NaCl, there is one mole of Na or 6.02*10^23 ions

In one gram of NaCl, there will be

  =6.02*10^23/58.5 sodium ions

In 30 grams of  NaCl, the number of sodium ions will be -

(6.02*10^23*30)/ 58.5

=3.08*10^23 ions

What type of rock would be formed in this plant-rich swamp?
adell [148]
We are asked to identify what type of rock would be formed in a plant-rich swamp. We all know that plant dies and the remain leaves in the soil called peat. Temperature, pressure and heat causes the remains to submerged under the soil bed layer and converts it into a waxy substance called kerogen. Kerogen then mixes with the rock under the soil bed layer to create what is called an oil shale. Oil shale is somehow similar to a coal. Both creates an energy when ignited. Therefore the correct answer to the question being asked is COAL or Oil Shale.
