Answer:
D BIOMASS ENERGY
Explanation:
Most biomass requires arable land to develop. This means
that land used for biofuel crops such as corn and soybeans
are unavailable to grow food or provide natural habitats.
Forested areas that have matured for decades (so-called
“old-growth forests”) are able to sequester more carbon
than newly planted areas.
It is important in gravimetric analysis to add an excess amount of precipitating ions to a solution containing an analyte because it helps to determine the mass of the analyte.
<h3>What is Gravimetric analysis?</h3>
This is a method which is used in the determination of the quantitative determination of the ion being analyzed(analyte) based on its mass.
Adding an excess amount of precipitating ions to a solution containing an analyte will make it easier for the mass of an analyte to be determined.
It is also important for the precipitate to be a pure substance with a definite and known composition which therefore makes it the most appropriate reason.

<span>1.Which best explains why ionization energy tends to decrease from the top to the bottom of a group?
D.Electrons get farther from the nucleus. </span>They experience a weaker attraction to the positive charge of the nucleus.<span>
3.When electrons are removed from the outermost shell of a calcium atom, the atom becomes
D. a cation that has a smaller radius than the atom. </span><span>Since the atom is losing an electron, it not only becomes positively charged, also the effective nuclear charge diminishes making the remaining electrons aproach the nucleus.</span>
