Hydroxide solution turns universal indicator blue because it is a strong base with a high concentration of hydroxide ions. These hydroxide ions react with the indicator molecules, causing a color change to blue. On the other hand, alkane solutions do not contain hydroxide ions and are typically neutral or slightly acidic, so they do not cause the indicator to turn blue. **

Hydroxide solution turns the universal indicator blue because it is a basic solution. Basic solutions have a higher concentration of hydroxide ions (OH-) which react with the indicator to produce a blue color. On the other hand, alkane solutions are neutral and do not have a significant concentration of hydroxide ions, so they do not cause the universal indicator to turn blue. **

Stock growth can be calculated using the formula: (Ending Stock Price - Beginning Stock Price) / Beginning Stock Price. This formula gives the percentage increase in the stock price over a certain period of time. For example, if a stock's price was $50 at the beginning of the year and $60 at the end of the year, the stock growth would be calculated as: ($60 - $50) / $50 = 0.20 or 20%. This means the stock grew by 20% over the year. **

A company's success is closely tied to its stock price because the stock price reflects investors' perceptions of the company's current and future performance.

This confidence is reflected in a higher stock price as demand for the company's shares increases. Conversely, if a company faces challenges or underperforms, its stock price is likely to decrease as investors adjust their expectations and valuation of the company. **
