HOW DO SCIENTISTS FORECAST SPACE WEATHER AND WHY
Fittoniya [83]
<span>Much like tornado watchers look to the skies for clues that a twister is forming, NASA and university scientists are watching the Sun in an effort to better predict space weather – blasts of particles from the Sun that impact the magnetosphere, the magnetic bubble around the Earth.</span>

The reaction below is at equilibrium at a temperature T. There are four possible changes listed. Select all the changes that wil
katovenus [111]

Answer:

The correct answer is B.

Explanation:

Heterogeneous equilibrium is that in which reagents and products are present in more than one phase.

When the reaction is carried out in a closed container, three equilibrium phases are present: solid magnesium oxide, solid magnesium sulfate and gaseous sulfur trioxide.

Hence, the equilibrium contant is given by:

K=\frac{[MgSO_4]}{[MgO][SO_3]} =\frac{1}{[SO_3]}

The concentrations in the equilibrium equation are the relationships of the real concentrations between the concentrations in the standard state. Since the standard state of a pure solid is the pure solid itself, the ratio of concentrations for a pure solid is equal to one.

Now, we analyse each statement:

I) As the reaction is endothermic (ΔH>0), increasing the temperature shifts the balance to the right because excess heat will be used to form more products.

II) Increasing the volume will decrease the concentration of SO₃, so Q>K and then this shifts the balance to the left.

III) As it is a heterogeneous balance, adding MgO will not affect the balance.

IV) Removing SO3 will decrease its concentration and therefore the reaction equilibrium will shift to the left.

Which compounds give a 1h nmr spectrum with two signals in a ratio of 2:3?
spayn [35]

Four option are provided as,

CH3CH2OCH2CH3

CH3CH2Cl

CH3CH2CH3

CH3OCH2CH2OCH3


CH3CH2Cl having 2 peaks of H NMR as 1st peak for quartet of 2 H and 2nd peak of triplet of 3 H and thus the ratio of both the peak is 2 :3 as the ratio indicates the number of hydrogen corresponds to each peak.
