The solubility of sodium chloride is 284g per 100g of water. what is the concentration in parts per million? (ppm)

As

Parts per million can be calculated by applying formula

Ppm=(mass of solute/mass of solution)x 1,000,000

In given condition

Mass of solute which is NaCl is 284g

Mass of solution which is water is 100g

Ppm=284/100x 1,000,000

=284000ppm

answer:

the reaction is type of combination reaction.

explanation:

on the product side, there are 2 molecules of bonded to fe   which means one atom of fe are combined two molecules of . so, balanced chemical equation becomes :

this reaction follows the reaction type of combination reaction. a combination reaction is defined as chemical reaction in which reactants combines together to form a single product.

rosa was looking for patterns to predict the products of chemical reactions. she recorded three similar decomposition reactions in the table.she should record 2licl + 3o2.

in the last row of the table. it is the thermal decomposition of chlorate lithium, hence, she should record these products as: lithium chloride ( 2licl ) and oxygen ( 3o2 )   2 > 2 licl + 3o2.
