Replicating experiments
(If u don’t mind can y mark me brainiest it would really help :) )
Answer:
Ti
Explanation:
Ti is titanium and does not share any similar properties with the likes of Si, silicon and At, astatine.
- Titanium is a transition metal and a solid.
- Silicon and Astatine are non - metals.
- Silicon and Astatine also belongs to the p-block on the periodic table whereas Titanium is found on the d-block.
- Silicon and Astatine would prefer to take part in reactions where they can gain electrons because they are non metals whereas Titanium due to its metallic property would prefer a reaction where it can lose electrons.
Answer:
Mechanical Energy to Thermal Energy
When you strike a match, it moves through the air until it rubs against a surface. The rubbing produces the heat required to light the match. This is a transformation from mechanical energy to thermal (heat) energy.

Answer:
(C) PCl₅
Explanation:
(A) AlCl₄⁻
The central atom has 4 bond pairs and 0 lone pair. Hybridization is sp³. The geometry is tetrahedral which has an angle of 109.5°.
(B) NH₃
The central atom has 3 bond pairs and 1 lone pair. Hybridization is sp³. The geometry is pyramidal which has an angle of approximately 107.5°.
(C) PCl₅
The central atom has 5 bond pairs and 0 lone pair. Hybridization is sp³d². The geometry is trigonal bipyramidal in which the equatorial bonds has an angle of 120° and axial bond has an angle of 90°.
(D) CO₂
The central atom has 4 bond pairs and 0 lone pair. Hybridization is sp. The geometry is linear which has an angle of 180°.
(E) H₂O
The central atom has 2 bond pairs and 2 lone pairs. Hybridization is sp³. The geometry is bent shape which has an angle of approximately 105.5°.
Season it well! (: Even salt can make a ton of a difference, honestly! Just try not to add too much of anything if it's meant to be healthy and you're just trying to lose weight!
Good luck, rockstar!
