In a reaction A+B---&gt;C, reactant A has 5g of product C has 9g of product. How many grams should reactant B contain?
Rzqust [24]

According to the law of conservation of Mass:

In a chemical reaction mass can neither be created nor be destroyed

So, we can say that: Mass of A + Mass of B = Mass of C

In the given reaction,

One of the reactants weigh 5 grams and another one weighs x grams

The mass of the product of this reaction is 9 grams

<u>Mass of reactant B:</u>

Mass of A + Mass of B = Mass of C

5 + x = 9

x = 4 grams

Iteru [2.4K]

Answer:

The two statements are all True for group 7 and 8 elements.

Explanation:

The Group 7 elements are known as the halogens. They are reactive non-metals and are always found in compounds with other elements. Chlorine, bromine and iodine are all halogens.

Chlorine, bromine and iodine are the three common Group 7 elements. Group 7 elements form salts when they react with metals. The term ‘halogen’ means 'salt former'.

In addition to the discription given to norble gases in the question which is true, norble gases;

  •     are inert gases located on the right of the periodic table.
  •     have a full-set of valence electrons, so they're stable, unreactive
  •     are colorless, odorless and tasteless.
  •     have low melting and low boiling points.
  •     can be found in small amounts in the Earth's crust and the Earth's atmosphere.
