In their experiment to form a primitive living cell, Urey and Miller set up various flasks with water vapor and the gases CO 2,

CH 4, and H 2. One flask also had electrodes to generate spark; another flask had everything but electrodes. Which of the flasks showed presence of coacervates, and why?
A. Only the flask with the electrodes because the electrodes were a source of electricity that simulated lighting
B. Only the flask without electrodes because the electricity generated from electrodes would have destroyed the coacervates
C. Both flasks because both were needed to provide all the ne

What causes the jet stream to move farther south?
Anni [7]
<span>Jet streams are the major means of transport for weather systems.  A jet stream is an area of strong winds ranging from 120-250 mph that can be thousands of miles long, a couple of hundred miles across and a few miles deep.  Jet streams usually sit at the boundary between the troposphere and the stratosphere at a level called the tropopause.  This means most jet streams are about 6-9 miles off the ground. Figure A is a cross section of a jet stream.
</span>

The dynamics of jet streams are actually quite complicated, so this is a very simplified version of what creates jets.  The basic idea that drives jet formation is this:  a strong horizontal temperature contrast, like the one between the North Pole and the equator, causes a dramatic increase in horizontal wind speed with height.  Therefore, a jet stream forms directly over the center of the strongest area of horizontal temperature difference, or the front.  As a general rule, a strong front has a jet stream directly above it that is parallel to it.  Figure B shows that jet streams are positioned just below the tropopause (the red lines) and above the fronts, in this case, the boundaries between two circulation cells carrying air of different temperatures.

How manymoles of each ion are present in 175 mL of 0.147 M Fe2(SO4)3?
lilavasa [31]

Answer: 0.0257 moles of Fe^{3+}  and 0.0257 moles of SO_4^{2-}

Explanation:

Molarity of a solution is defined as the number of moles of solute dissolved per Liter of the solution.

Molarity=\frac{moles}{\text {Volume in L}}

moles of  Fe_2(SO_4)_3=Molarity\times {\text {Volume in L}}=0.147\times 0.175L=0.0257moles

The balanced reaction for dissociation will be:

Fe_2(SO_4)_3\rightarrow Fe^{3+}+SO_4^{2-}

According to stoichiometry:  

1 mole of Fe_2(SO_4)_3 gives 1 mole of Fe^{3+}  and 1 mole of SO_4^{2-}

Thus there will be 0.0257 moles of Fe^{3+}  and 0.0257 moles of SO_4^{2-}

Which of the following pairs of reactants is not correctly listed with its product solution? A. Strong base-strong acid reactant
alexandr1967 [171]

Answer: Option B

Explanation: when strong acid react with strong base, the resulting solution is neutral as in the case of HCl and NaOH

HCl + NaOH —> NaCl + H2O

From the equation obtained, The salt ( NaCl) obtained is a normal salt which is neutral.
