I believe it’s A, they form whole-number ratios in the compound
Nice question. A cow has 4 udders
Answer:
To regulate the gas pressure in the lighter tank and avoid build-up of pressure.
Explanation:
- First, you need to understand the properties of this organic molecule. Butane. C₄H₁₀ is a colorless, odorless, but HIGHLY FLAMMABLE liquefied gas. The liquid is flammable at 25⁰C whilst the vapor is flammable at 15⁰C. As you can see, this is an extremely flammable gas. It has a high vapor pressure (tendency by liquids to escape as gas molecules)
- Any external heat source induces a pressure build up that might cause the gas to explode when there is an open flame.
- Combining the two points above, a thermo-regulated water bath that has a lower temperature (below 15⁰C) will be need to prevent the pressure build up and ensure that any leakage will not have a high vapor pressure.
Answer:
Explanation:
Density can be defined as mass divided by volume. But 2 objects made of the same material will have the same density regardless of their volume.
Covalent bonding - giant covalent structures. ... The atoms are usually arranged into giant regular lattices - extremely strong structures because of the many bonds involved. The graphic shows the molecular structure of diamond and graphite: two allotropes of carbon, and of silica.
