Answer:
ONE: spoon/ catapult
TWO: ball holder
THREE: the joint
FOUR: the rotater
FIVE: I think it is a lever that picks up the big spoon/ catapult
SIX: I don't know the chapter
The working equation for this is:
Tbp,soln - Tbp,water = i*Kb*m
where
Kb for water is 0.512 °C/molal
m is the molality (mol solute/kg solvent)
i is the van't hoff factor which represents the number of ions dissociated for strong electrolytes
Tbp,water is the boiling point of water which is 100°C
1. <span>1.50 moles of lioh (strong electrolyte) and 3.00 moles of koh (strong electrolyte) each in 1.0 kg of water
i = 2 for LiOH and 2 for KOH
Then,
</span>Tbp,soln - 100 = (2+2)(0.512)((1.5+3)/1 kg)
Tbp,soln = 109.22°C
<span>
2. </span><span>0.40 mole of al(no3)3 (strong electrolyte) and 0.40 mole of cscl (strong electrolyte) each in 1.0 kg of water
</span>
i = 4 for al(no3)3 and 2 for cscl
Then,
Tbp,soln - 100 = (4+2)(0.512)((0.4+0.4)/1 kg)
Tbp,soln = 102.46°C
<em>Thus, the first solution will have a higher boiling point.</em>
To find this you have to find the molar mass of CO2 which you can get on the periodic table, 12 + 16 + 16 = 44 g/mol
4.49 x 10^0 / 44 g/mol = .1020 mol CO2
1 mol = 6.022 x 10^23 molecules (avogadros number)
so .1020 mol x 6.022 x 10^23 =
6.14 x 10 ^22 molecules CO2
