Answer:
Element X is Arsenic (As)
Explanation:
- Elements in the periodic table are either metals, non-metals or metalloids.
- Metals are elements that react by losing electrons to obtain a stable configuration and form cation.
- Non-metals are those elements that react by gaining electrons to form a stable configuration and form anion.
- Metalloids are elements in the periodic table that have both metallic and non-metallic properties.
- Examples of metalloids include Selenium, Arsenic, Boron, etc.
- Arsenic is a metalloid in period 4 (four energy levels) with five valence electrons.
mg reacts with the acid and produce visible bubbles of hydrogen gas. they will produce audible pops as the hydrogen ignites. ... Hydrochloric acid is a corrosive liquid. Hydrogen gas is explosive.
Answer is: glycerol because it is more viscous and has a larger molar mass.
Viscosity depends on intermolecular interactions.
The predominant intermolecular force in water and glycerol is hydrogen bonding.
Hydrogen bond is an electrostatic attraction between two polar groups in which one group has hydrogen atom (H) and another group has highly electronegative atom such as nitrogen (like in this molecule), oxygen (O) or fluorine (F).
The pair which consist of molecules having the same geometry is CH2CCI2 and CH2CH2.
Both of these molecules contain double bonds, which has sp^2 hybridization and they possess a trigonal planar geometry. In trigonal planar geometry, the molecule consist of three equally spaced sp^2 hybrid orbitals, which arranged at angle 120 degree.
