Accepted Answer

Welcome back everyone hydrogen peroxide, H 202 as a compound used as a bleaching agent. Its melting point and boiling point R negative 0.43 Celsius and 150.2 Celsius respectively. What would be the physical state of hydrogen peroxide? If the surrounding temperature is 40 degrees Celsius. So writing out what the prompt tells us, we have a melting point of peroxide Equal to negative 0.43°C and we have a boiling point of peroxide Equal to 150.2°C. This means that when the temperature is less than the melting point, negative 0.43°C, we would therefore have solid peroxide. And based on the boiling point, we can say that when the temperature is greater than 150.2°C, we therefore have gaseous peroxide. And finally, I'm sorry this is H 202. And finally we can say that when the temperature is between our given boiling point of 150.2°C and between our given melting point of negative 0.43°C. In which because the surroundings are according to the prompt 40°C, then therefore peroxide would be in its liquid phase. So we can just actually write the symbol in parentheses as liquid and this would be the physical state of our compound. So when the surrounding temperature is 40°C, we have peroxide in its liquid form. This will correspond to choice being the multiple choice as our final answer. I hope this made sense and let us know if you have any questions.
