167 mL
P1V1 = P2V2
P1 = .8 atm
V1 = 250 mL
P2 = 1.2 atm
Solve for V2 —> V2 = P1V1/P2
V2 = (0.8 atm)(250 mL) / (1.2 atm) = 167 mL
Answer: Hydrogen belongs to group 1 metal elements in the periodic table.
Explanation:
The hydrogen is a highly active metal. It has a single electron in its valence shell and it can donate its electron to other metal atoms. Thus forming metal hydrides. The hydrogen when ignited it reacts with oxygen and burns explosively this is indicative of high reactivity and spontaneous reactivity of hydrogen atom.
Answer:
For example, the bond between the sodium and chlorine atoms in sodium chloride (NaCl) is formed by the transfer of an electron from sodium to chlorine, creating Na + and Cl – ions. ... The electrostatic attraction between these ions provides the bonding in NaCl.
The term deforestation denotes the change of intended land use from forest to non-forest (urban, agricultural, etc.), as distinct from the cutting of selected tree stems. ... Thus the global net change in forest cover is the sum of all positive and negative changes in forest area (increases and decreases).
