Change 2.6 km/day to m/week
professor190 [17]
First, we need to transform km to meters.

1 km = 1000 meters

2.6 * 1000 = 2600

Now, there are 7 days in a week. 

Multiply.

2600 * 7 = 18,200

Final answer: 18,200 meters a week

URGENT! Consider the following decomposition reaction of ammonium carbonate ((NH4)2CO3):
dexar [7]
<span>Using PV=nRT to find the moles and then convert back.
</span><span>4x=.8944
</span><span>solve for x then use the pressure for lets say CO2 put that into PV=nRT then solve for n then convert over.
</span>
<span>(.2236)(2)/(298*.08206) = .0183*96g/mol = 1.76g
</span>
<span>For C:

[NH3]^2[CO2][H2O] = Kp
x=0.2236 (2*.2236)^2(.2236)*(.2236)
  =0.001
