Read the reaction and the statement. 2X(g) + Y2(g) ⇌ 2XY(s)

The equilibrium constant for the chemical reaction is found to be 20 at 150 K.

If the concentration of X is 4.0 × 10-2 M, what is the concentration of the Y2 gas?

5.50 M

40.0 M

31.25 M

8.0 M

practical process described pest part of scientific investigation.

because practical knowledge is powerful then therotical knowledge.

b.false that your answer

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.
