Answer:
Cookies definitely obeys the law of conservation.`
Explanation:
As, When Maria mixes up the ingredients, Water was also one among them
And, Initially When she was measuring the weight of Ingredients, Weight of Water was coming,
But,
When She baked the cookies , water from the cookies got evaporated , and thus weight coming was decreased finally.
Considering Cookies and Environment Whole as a system You can clearly say that they obeys Law of conservation of mass , As Water is present in Environment for now.
Diamond consists of carbon atoms tetrahedrally arranged and bonded by strong covalent bonds. Graphite consists of carbon atoms arranged in hexagonal rings and in layers. Each carbon atom is bonded to three other atoms arranged hexagonally in layers.
Pretty sure it’s to see whether carbon dioxide is formed in each bottle so if it does form then the balloon would expand
Answer:
pH = 9: Basic; pH = 2.3: acidic; pH = 11: basic; pH = 5: Acidic; [H⁺] = 0.0056M: Acidic; [H⁺] = 3.45E-9M: Basic
Explanation:
A solution is defined as acidic when pH < 7 and as basic when pH > 7.
Also, pH = -log[H⁺].
Thus:
pH = 9: >7 → Basic
pH = 2.3: <7 → Acidic
pH = 11: >7 → Basic
pH = 5: <7 → Acidic
[H⁺] = 0.0056M, pH = -log0.0056M = 2.25: <7: Acidic
[H⁺] = 3.45E-9M, pH = 8.46: > 7: Basic
