Answer:
85.384 atm or 64608.13086 mmHg
Explanation:
PV= NRT
P= NRT/V
n= mols
R= gas constant (i used .0821 for atm)
T= Temp in Kelvins (Celsius degrees + 273)
V= in L
(65molsx480kx.0821)/30L
Period. Groups/families are the vertical columns on the periodic table.
A polar covalent bond is a covalent bond in
which the atoms have an unequal attraction for
electrons and so the sharing is unequal. ... The
atom with the greater electronegativity acquires
a partial negative charge, while the atom with
the lesser electronegativity acquires a partial
positive charge.
here you go
Answer:180°
Explanation:
According to VSEPR theory, if the valence shell of the ceteral atom in a molecule contains only two valence electron pairs, the valence electron pairs will arrange themselves along a straight line, forming a bond angle of 180°
To find the formulae, you must add as many of the ions together to get a neutral charge. For example, one Li^+ ion and one NO2^- ion give LiNO2, which is lithium nitrite, but since CO3^2- has a charge of -2, it needs 2 Li^+ ions to make the neutral compound Li2CO3, lithium carbonate. Similarly, Cu^2+ needs 2 NO2^- ions to make the neutral compound Cu(NO2)2, copper(II) nitrite. To name these, simply add together the names of the ions used. Li^+ is lithium, Cu^2+ is copper(II), and Ba^2+ is barium. The negatively charged ions are named as nitrite for NO2^-, carbonate for CO3^2-, bisulfate for HSO4^- and phosphate for PO4^3-.
