Chapter 4, Problem 21STP

Interpretation Introduction

Interpretation:

Whether Statement I and Statement II are true or false and whether statement-II is the correct explanation for statement-I needs to be determined.

Concept introduction:

Heterogeneous mixture is a composition of non-uniform compound that has two or more phases.

Answer to Problem 21STP

Statement-I is true, statement-II is true. But statement II is not the correct explanation for statement-I.

Explanation of Solution

Statement-I and statement II both are true. A mixture of sand and water is heterogeneous because sand does not dissolve in water. And water is a compound formed from two hydrogen atoms and one oxygen atom. There is covalent bond between H and O atoms in water.

Conclusion

Thus, statement-I and statement-II both are correct but statement-II is not the correct explanation for statement-I.
