Answer:
C: Mg
Explanation:
Hybridization of atomic orbitals is a fundamental concept introduced by Pauling that describes the mixing of orbitals at an atom which adds a definite direction to the Lewis - shared electron pair or electron chemical - bond concept.
Carbon(C) can hybridized on sp, sp2 and sp3 simply because it's valence shell gives room for it.
For silicon(si), when forming covalent bonds with other atoms, it's 3s and 3p orbitals are mixed with each other to form new hybrid orbitals.
Magnesium in itself doesn't hybridized except in magnesium hydrides.
Boron orbitals(B): when boron forms bonds with three other atoms like borazine, they are hybridized to either the sp2 or hybridized to the sp3 which occurs when boron forms bonds with four atoms just as is in metal borohydrides.

From the Dalton's law of partial pressures, the pressure of the hydrogen gas is 91.83 kPa.
<h3>What is partial pressure?</h3>
In a mixture of gases, the total pressure is the sum of the pressures of the individual gases in the mixture according to the Dalton's law of partial pressures.
In this case, the partial pressure of the hydrogen gas is Phydrogen, the partial pressure of water is Pwater and the total pressure is PT.
Hence;
Phydrogen = PT - Pwater
95 - 3.17 = 91.83 kPa

Answer:
A. Element
B. Compound
C. Compound
D. Element
E. Compound
F. Compound
Explanation:
Elements are what is already on the periodic table and compounds are the substances created when they are combined.
1) during daylight, especially around noon, the relatively high air **temperature** and low humidity caused high evaporation, extracting pore water from the beach and leaving the **salt** behind, thereby resulting in high salinity near the beach surface (intertidal zone)
2) • algae and other intertidal plants grow in the abundant sunlight and support an entire food chain of animals
• constant wave action supplies the tide pool with **nutrients** and oxygen
• food is abundant
• a varied substrate provides hiding places and surfaces to cling to
3) the intertidal zone is one of a number of **marine** biomes or habitats, including: estuary (spray zone), neritic (lower/shallow zone), surface (middle zone), deep zones (high zones)
