Can a wheelchair fit through a 30 inch door? With a door fully opened, most doorways provide a clear opening up to two inches narrower than the size of the door. Given a direct approach, many wheelchairs will fit through a clear opening 30 inches wide. This will add about 1 or so inches to […]

What is the ratio of carbon monoxide to Mass? Every sample of carbon monoxide contains 16.0 g of oxygen for every 12.0 g of carbon. This is a mass ratio of oxygen to carbon of 1.33 to 1. Is carbon dioxide one kind of atom? Recall that an element is a pure substance made of […]

How is the law of conservation of energy shown in photosynthesis and cellular respiration? Cellular respiration uses oxygen and has it’s waste product of carbon dioxide (CO2). How does photosynthesis demonstrate the law of conservation? The AMOUNT of carbon-dioxide atoms released by respiration are EXACTLY EQUAL to the atoms of these materials contained in the […]

Why do larger alkanes have higher boiling points? Alkanes experience inter-molecular van der Waals forces. Stronger inter-molecular van der Waals forces give rise to greater boiling points of alkanes. Which group has the lowest boiling point? noble gases Do aldehydes have higher boiling points than alcohols? The polar carbon-to-oxygen double bond causes aldehydes and ketones […]

Do arctic foxes have good hearing? Arctic foxes have incredible hearing that allows them to identify the precise location of their prey under the snow. To catch their prey, they leap up in the air and pounce down into the snow on the prey below. How fast is an arctic fox? 30 miles per hour […]
