Answer:
c. reducing oxygen level on hemoglobin.
Explanation:
Carbon monoxide, whose chemical formula is CO, is an odorless, colorless, flammable and highly toxic gas. It can cause death when breathing at difficult levels. It occurs when combustible materials such as gas, gasoline, kerosene, coal, oil, tobacco or wood are burned in low oxygen environments. Fireplaces, boilers, water heaters and household appliances that burn fuel, such as stoves, can also produce it if they are not working properly. Vehicles stopped with the engine running also fire him.
Carbon monoxide modifies the amount of oxygen available to cells, which hinders cellular function.
Carbon monoxide binds tightly to hemoglobin preventing the red blood cell from carrying adequate oxygen, leading to hypoxic injury. Other chemicals such as carbon tetrachloride promote free radicals, which injure cells and destroy cellular membranes.
Answer:
student A
Explanation:
v = s ÷ t (speed = distance ÷ time)
v = 6m ÷ 2s
v = 3m/s
Answer:
radical-initiated
Explanation:
Radical-initiated polymerization is unpredictable and difficult to control. The reaction proceeds indiscriminately and produces shortened chains, loops, and branches that create holes in the polymer. This reduces its mass to volume ratio.
I got BH3, but just letting you know I am 97% sure on that. I hope it helps!!
