Explanation:
Since the atomic structure is at it's neutral state
It bonds to skin because
solid polymer requires the presence of water to get things started, be it in the air or on your skin. Without a little moisture, SuperGlue can't bond anything. This explains why the glue is so good at sticking fingers together.
Answer:
1. 1.25 mol ants x 6.02*10^23 ants/1 mol ants = 7.53*10^23 ants
2. 4.92*10^26 pencils x 1 mol pencils/6.02*10^23 pencils = 817 mol pencils
3. 0.26 mol molecules x 6.02*10^23 molecules/1 mol molecules = 1.6*10^23 molecules
4. 3.46*10^19 molecules x 1 mol molecules/6.02*10^23 molecules = 5.75*10^-5 mol molecules
5. 5.3*10^20 atoms x 1 mol atoms/6.02*10^23 atoms = 8.8 mol atoms
6. 0.11 mol atoms x 6.02*10^23 atoms/1 mol atoms = 6.6*10^22 atoms
I would suggest looking into "dimensional analysis" for help with this type of material. Dimensional analysis will stick with you all throughout chemistry, so picking it up will be extremely beneficial.
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.
