Answer:
Choice 'B'
Explanation:
Choice B => SCl₂ => 2 bonded pairs + 2 nonbonded pairs => 4 electron pairs => AX₄ parent => tetrahedral parent, but the shape is defined only by what's bonded to the central element that is, sulfur bonded to two Cl substrates. The electron pairs will assume positions in space (to minimize repulsion forces) like a regular tetrahedron (AX₄) but will have an AX₂E₂ geometry which is a Bent Geometry.
Suggest searching molecular geometry images online. Look for derivatives of AX₄ geometries. Example: H₂O (AX₂E₂ bent geometry; also a derivative of AX₄ tetrahedral parent geometry).

Explanation: <u><em>
These threats are destroying forests, which as Earth's lungs are the very solution to climate change in the first place.</em></u></h2>
<h2><u><em>
All over the world, the Rainforest Alliance’s work is assisting communities and businesses as they keep forests healthy and recycling greenhouse gases. We’re helping farming communities adapt to the impacts of climate change, and we’re working with forestry operations as they adopt techniques that benefit ecosystems and pursue innovative carbon sequestration projects.</em></u></h2>
Answer:
Fish need to be aerodynamic to move quickly. If they had legs they woulf be less aerodynamic and unable to get away from predators.
Answer:
Hydrogen, H_2
Explanation:
mass of each gas is 10.0 g
number of mole = mass/ molar mass
number of moles is directly proportional to volume at constant temp and pressure
this implies that the volume is inversely proportional to molar mass. And Among all the gases in periodic table the molar mass of Hydrogen is the least.
molar mass of H2=2 g/mol
Since, H2 has minimum molar mass then for the same mass of the gases Hydrogen will have maximum volume.
