Ni(OH)₂ ⇄ Ni⁺² + 2 OH⁻
Ksp = [Ni⁺²][OH⁻]² = S (2S)² = 4S³
where S is molar solubility.
at pH = 10
[H⁺] = 10⁻¹⁰
[H⁺][OH⁻] = 10⁻¹⁴
so [OH⁻] = 10⁻⁴ M
Ksp = S [10⁻⁴ + 2S]²
Ksp is very small so the molar solubility of OH⁻ will be very small
so (10⁻⁴ + 2S) is about 10⁻⁴
so Ksp = S x 10⁻⁸
S =
= 6 x 10⁻⁸ M
The answer is b.gold can’t really explain but the answer is b.
Answer:
Amylase.
Explanation:
The process of digestion begin to start in mouth when food mix with saliva. An enzyme is released which is called Amylase help in digestion of carbohydrates.
Which components make up bronfenbrenner's ecological theory?
Bronfenbrenner divided the person's environment into five different systems:
- microsystem
- mesosystem
- exosystem
- macrosystem
- chronosystem.
What is bronfenbrenner's ecological theory?
- Bronfenbrenner's ecological systems theory views child development as a complex system of relationships affected by multiple levels of the surrounding environment, from immediate settings of family and school to broad cultural values, laws, and customs.
- To study a child's development then, we must look not only at the child and her immediate environment, but also at the interaction of the larger environment as well.
- The microsystem is the most influential level of the ecological systems theory.
- This is the most immediate environmental settings containing the developing child, such as family and school.
- Bronfenbrenner's ecological systems theory has implications for educational practice.
