which information must be known about a compound to find the molecular formula from the empirical formula​

Biology
1 answer:
LenKa [72]3 years ago
4 0

Answer:

Molecular mass or vapor density

Explanation:

The empirical formula is the simplest formula of a compound. The molecular formula expresses the exact formula of the compound. To derive the molecular formula, we need information about its molecular mass or if given the vapor density.

                (Empirical Formula)n = Molecular formula ------(i)

         n = number of repeating units of the empirical formula present in one                        mole of the molecule

          also, (molar mass of empirical formula)n = molar mass of compound

      From here, we can find n and insert in (i) above.

List two ways in which the atmosphere would be impacted in the absence of the biosphere?
Leya [2.2K]

Answer:

Biosphere comprises all the life that exists on earth including animals, plants, water bodies, microorganisms, algae, fungi etc.

If there would be no biosphere on earth the atmosphere would be quite different. There would be no oxygen to support because oxygen is liberated by plants in photosynthesis so no plants means no oxygen. The earth would be a planet without life just like Venus and Mars. Therefore, no organism would be surviving in the world.

There would be no  negligible green house effect and global warming since it is all created due to activities of men.The earth's atmosphere would be much cleaner and with lesser amount of CO2 and O2 but no organism would be there to use them.

Hope it help!

LUCKY_DIMON [66]
<span>Carnivorous plants have evolved mechanisms that trap and digest small animals. The products of this digestion are used to supplement the plant's supply of "minerals". Carnivorous plants are a specialized group of plants that grow in wet, acidic soils. Plants must obtain the mineral nutrients from their growing medium.</span>

If someone could dig a safe tunnel through the earth how long would it take to free fall to the center?
Reptile [31]

Answer: A scenario often presented to introductory physics classes is that of a "gravity tunnel" — a tube drilled from one side of the Earth to the other through the planet's center. The answer taught for nearly a half-century for how long a fall through such a hole would take was about 42 minutes and 12 seconds.

Explanation: However, solar and lunar gravity, which also perturb orbiting satellites, would eventually pull you into the tunnel wall anyway [source: Darling ]. Strike a chord: Fun fact: A straight line from any point to any other point through the planet would take the same amount of time to fall through like a tunnel through Earth's center.
