Answer: Carbon Monoxide is a very harmful and toxic gas which is formed from incomplete combustion of carbon.
Explanation: red blood cells contain haemoglobin ,which are responsible for carrying oxygen into our body system. So oxygen combines with haemagoblin to form oxyhaemogoblin in the red blood cells .
so if a person starts to intake cigarettes which contain high amounts of carbon monoxide ,it reduces oxyhaemogoblin formation because it binds very tightly to the haemogoblin .then carboxyhaemogoblin is formed and its permanent so causing reduction in aerobic respiration, and reduction in oxygen transport and causing damages to heart muscles.

Given what we know, we can confirm that the free-swimming organic and inorganic molecules in earth's early seas are called the primordial soup.
<h3>What was the primordial soup?</h3>
- The primordial soup was the contents of the seas of the early Earth.
- This was considered as a chemical solution.
- It consisted of terrestrial compounds as well as alien substances that arrived with comet and asteroid collisions.
Therefore, we can confirm that the free-swimming organic and inorganic molecules in earth's early seas are often referred to by the scientific community as the primordial soup.

The answer to number two is true
Answer: Mass is more than 145 g but less than 160 g
Explanation: Acid and limestone reacts forming water, salt and
Carbon dioxide CO2. Because CO2 is gas it is bubbled away from
glass and that's why mass is less than 160 g. Because limestone
releases CO2 and products from acid remain in solution, mass is more than 145 g. If amount of acid in moles is enough, all limestone reacts.
Roughly 44% of mass of limestone CaCO3 forms CO2 and we can estimate mass of gas is 0.44·15 g = 6,6g , so mass would be 153 g
