WHAT HAPPENS WHEN IT BURNS? Officials warned the controlled burn would send phosgene and hydrogen chloride into the air. Phosgene is a highly toxic, colorless gas with a strong odor that can cause vomiting and breathing trouble and was used as a weapon in World War I. Phosgene is considered ...
Matter-energy transformations (e.g., gasoline is converted to energy when it burns, fat is converted to energy when a person loses weight, plants convert sunlight into food) are common in Level 3 accounts. The quotes below give examples of Level 3 thinking. Justin’s account of why a ...
When magnesium burns in carbon dioxide (CO₂), a chemical reaction occurs that results in the formation of magnesium oxide (MgO) and carbon (C). Here’s a step-by-step breakdown of the process:Step 1: Understanding the Reactants</stro
Although hydrogen cyanide poisoning in pets isn’t as common, it’s still a potential danger when it comes to house fires. If your pet is exposed to hydrogen cyanide poisoning, your vet will likely treat them with oxygen therapy and supportive care depending on the severity. Pneumonia Pneumonia...
Which equation represents the combustion of hydrogen gas? a) H2 + O2 to H2O2 b) H2 + O2 to H2O What is the difference between fire and combustion? The combustion of gaseous ethane in air forms carbon dioxide and water vapor. Write the balanced chemical equation for ...

Describe the energy transformations involved when a yo-yo is thrown downward and then climbs back up its string to be caught in the user's hand. What happens to the core of a high mass star after it runs out of hydrogen? Cite the three major differences between ...
Third, upholstery foam produces deadly gases when it burns. Ignited polyfoam sofas can reach temperatures over 1400 degrees Fahrenheit within minutes. Studies show that PU foam releases significantly higher amounts of hydrogen cyanide at a faster rate than cotton, wool, and nylon (source and source...
What happens when acids react with bases? Acids and bases neutralize each other, producing water and a salt in a reaction known as neutralization. 5 How do acids and bases differ in their reaction with metals? Acids react with metals to produce hydrogen gas, while bases typically do not reac...
As such, any increase in the cost of oil sparks even more interest in gasoline alternatives. Things likeelectric carsandhydrogen fuel cellsare being talked about as feasible alternatives to oil. But, not lost in the mix are the biofuels, fuels made from biological ingredients instead of fossil...
