Answer:
Yes it is a scientific model because it is an outlook of a winter outlook and winter is a season and a type of weather and weather is meteorology and meteorology is a type of science so yes it is a scientific model.
Explanation:
How does the law of conservation of mass apply to this reaction: C2H4 + O2 → H2O + CO2?
The hydrogen ion concentration, [H ], in the solution of phenol red solution of pH 11.20 is 6.3 X
moles/litre.
Explanation:
Data given:
basic solution of phenol red is given as it has pH of 11.2
hydrogen ion concentration = ?
the hydrogen ion concentration is calculated by using the following formula:
pH = -
[
]
Rearranging the equation:
[
] = 
Putting the values in the above equation:
[
] = 
[
] = 6.3 X
moles/litre
The hydrogen ion concentration is very small and the solution of phenol red is basic in nature. The pH of 11.2 also indicates that solution is basic and teh color of the solution is bright pink.
