What is the pressure of the gas if the temperature is increased to 600 degree C at constant volume ? 0 86 atm 2 6 atm 4 0 atm 6 0 atm 6 9 atm 2.7 atm = torr 2.052 Times 10^3 1.71 Times 10^-4 2.052 Times 10^4 205 2.052 Times 10^5 The correct formula for the hydroxide ion and sulfate ion are (in order)Explanation / Answer
10) a)Electronegativity increases as you move across the periodic table from left to right. This occurs due to a greater charge on the nucleus, causing the electron bonding pairs to be very attracted to atoms placed further right on the periodic table. Fluorine is the mostelectronegative element.
11) c)Trigonal pyramidal is a molecular shape that results when there are three bonds and one lone pair on the central atom in the molecule. Molecules with an tetrahedral electron pair geometries have sp3 hybridization at the central atom. Ammonia (NH3) is a trigonal pyramidal molecule.
12)B) A strong electrolyte is a solute that completely, or almost completely, ionizes or dissociates in a solution. These ions are good conductors of electric current in the solution
13) E BF3. B has only three valence electrons: 1s2 2s2 2p1. So it can only share three pairs.
14) B) FeI3
15)A
16)B
17)E) 63%
18) D)[Ar]4s1
19)D
20)p1/T1 = P2/T2 = 1.5/498 = P2/873
p2 = 1.5*873/ 498
P2 = 2.6atm
