Answer:
Explanation:
Colligative properties are the properties of solutions that depends on the number of solute particles in solution rather than on their chemical identity.
Answer:
Dermal tissue of the stems and leaves is covered by a waxy cuticle that prevents evaporative water loss. Stomata are specialized pores that allow gas exchange through holes in the cuticle. Unlike the stem and leaves, the root epidermis is not covered by a waxy cuticle which would prevent absorption of water.
Explanation:
When two atoms combine, the overlap of their atomic orbitals produces molecular orbitals.
Answer:
The statement is TRUE.
Explanation:
In endothermic reactions, heat is absorbed (imagine that heat would be a reactive in the reaction). The enthalpy (H) of the products is greater than that of the reagents and the deltaH is positive. An example of this reaction is the decomposition of H20:
2H20 -> 2H2 + 02
I think d is wrong because Everything else is correct for sure. also, minerals vary in the position they hold and have different chemical compounds.
