Only 3.<\/p>\n<p>Carbon dioxide (CO2) is a colorless, odorless gas that is slightly heavier than air. It is a major component of the Earth&#8217;s atmosphere, and it is also found in volcanic gases, soda water, and carbonated beverages.<\/p>\n<p>CO2 is not a poisonous gas. In fact, it is essential for life on Earth. Plants use CO2 to produce food through photosynthesis. Humans and other animals exhale CO2 as a waste product.<\/p>\n<p>CO2 is an acidic oxide. This means that it reacts with water to form carbonic acid. Carbonic acid is a weak acid, but it can cause some materials to corrode.<\/p>\n<p>CO2 does turn lime water milky. Lime water is a solution of calcium hydroxide. When CO2 is added to lime water, it reacts with the calcium hydroxide to form calcium carbonate. Calcium carbonate is a white solid, which is what causes the lime water to turn milky.<\/p>\n<p>Therefore, only statement 3 is correct.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>[amp_mcq option1=&#8221;1 and 2&#8243; option2=&#8221;2 and 3&#8243; option3=&#8221;Only 3&#8243; option4=&#8221;1 and 3&#8243; correct=&#8221;option3&#8243;]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[636],"tags":[],"class_list":["post-5097","post","type-post","status-publish","format-standard","hentry","category-non-metal-and-its-compounds","no-featured-image-padding"],"yoast_head":"<!-- This site is optimized with the Yoast SEO Premium plugin v22.2 (Yoast SEO v23.3) - https:\/\/yoast.com\/wordpress\/plugins\/seo\/ -->\n<title>Following statements are made in connection with Carbon dioxide (CO2). 1.
