Every Sunday my family and I go to ( look up on google an old person home in yo ur city) to visit my (grandma or grandpa ). We always bring her icecream from McDonald’s because it brings her joy and she really likes it. While we were there we played jenga with her aswell as listened to her tell stories of her youth. It really brings happiness to her when she thinks back at her fun moments in life. I really like hearing them too. When I hear her stories it shows me the difference in times we grew up in. While I was there I meet her new friend Nancy , Nancy is 81 years old and has dementia, it makes me very sad to see her she asked who I was about 6 times being there in a time span of 2 hours. When I go there it makes me feel grateful knowing my family loves me and each other. Most elderly people who live there do not see their family at all. It taught me a life lesson that family is everything and we should cherish each moments in life good or bad.

Here are possible changes that could take place if the concentration of oxygen in theatmosphere were halved:1.Iron and steel would rust more slowly, prolonging the useful life of many objects madefrom these materials.2.Fires would burn less vigorously and produce more CO and soot. Logs in your fireplacemight last longer.3.Your body can adapt (just as it does at higher elevations) to lower levels of oxygen. But inthis case, the level may be too low for metabolic processes involving oxygen to occur at fastenough rates for life as we currently know it.33.Explain why CO is called the “silent killer.” Select two other pollutants for which this namewould not apply and explain why not.Answer:CO is termed the “silent killer” because your senses cannot detect this colorless, tasteless,and odorless gas. The same term cannot be applied to pollutants such as O3or SO2becauseeach has a distinctive odor that can be detected at concentrations below the level of toxicity.34.Cigarette smoke is 2–3% carbon monoxide.a.How many parts per million is this?b.How does this value compare with the National Ambient Air Quality Standards for CO inboth a 1-hour and an 8-hour period?c.Propose a reason why smokers do not succumb to carbon monoxide poisoning.Answer:a. To convert from percent to ppm, move the decimal point 4 places to the right.Alternatively:3%=3pph3pph×1,000,000ppm100pph=30,000ppmb.The NAAQS for CO in an 8-hour period is 9 ppm. The concentration of CO in cigarettesmoke is over three thousand times the 8-hour standard. The NAAS for CO
