I mostly believe in between D and B beacuse K3po4 and caco3 is not an element equation
Answer:9.49g/mL
Explanation:
Mass of toy = 43.672g
Volume of water = 34.4mL
Volume of toy + volume of water = 39mL
Volume of toy = 39 — 34.4 = 4.6mL
Density = Mass /volume
Density = 43.672/4.6 = 9.49g/mL
"One has more oxygen atoms than the other" best distinguishes carbon dioxide from carbon monoxide
<u>Explanation</u>:
In both carbon monoxide and carbon dioxide, there is the presence of carbon and oxygen. However,they vary depending on the number of oxygen atoms.In carbon monoxide, there is the presence of one only carbon and oxygen atom. Thus carbon monoxide is chemically represented as CO. Only about 0.2%ppm of carbon monoxide present in air. carbon monoxide is toxic and causes death in human when not consumed is correct proportion.
Whereas in carbon dioxide, only one carbon atom,and two oxygen atom and hence chemically represented as co2.
