Answer:
<em>A ) 7 GRAMS</em>
Explanation:
7 grams.
The sum of the reactants must equal the sum of the products.
Reactant = 100 grams
Products = 100 g mercuric oxide - 93 g mercury which equals 7 grams oxygen.
The technique that is known to be illustrated is said to be DNA hybridization.
<h3>What is DNA hybridization?</h3>
In the study of genome, DNA hybridization is known to be a kind of a molecular biology method that is often used to know the measures or the degree of genetic similarity that exist between a given pools of DNA sequences.
DNA hybridization is also seen as ability of two given strand of complementary DNA that tends to pair with another strand and it is one that can be used to find out other similar DNA sequences in two other kinds of species or within a given genome of a single species.
Note that in the case above, The technique that is known to be illustrated is said to be DNA hybridization.

Mainly, the mass of a planet doesn't matter, considering many planets are made up of gas, and how in different situations, atmospheres can be destroyed (The Sunburnt off Mercury's Atmosphere). However, in some cases, the planet can be in a good situation on the galactic map and have great conditions for an atmosphere, such as Earth. In which case, the mass of an object can attract a smaller object, causing gravity. Therefore, the bigger the mass of a planet when in right and specific conditions, the more atmosphere it can attract, if there is any floating by the planet.
If it is bigger it will have more gravitational influence and therefore gather more gases.

The angle of elevation of the ground is the angle between the ground and the line of sight
The angle of elevation of the ground is 30.46 degrees
<h3>How to calculate the angle of elevation</h3>
The angle of elevation is calculated using the following tangent ratio

Evaluate the quotient

Take the arc tan of both sides

Using a calculator, we have:
= 30.46
Hence, the angle of elevation of the ground to the nearest tenth of a degree is 30.46 degrees
