1) low pressure systems tend to result in unsettled weather and may present clouds high winds and precipitation. As low pressure intensifies storms or hurricane may be formed

1. because the air continues to cool and the water vapor may condense into precipitation, which results in unsettled weather

2. air is more dense in a region of high pressure, so the air pushes toward less dense regions. the air begins to warm as it descends, gets rid of the formation of clouds

1. 3A + 2B + C + 2D + 20 kJ

erma4kov [3.2K]

Answer:

a) the reverse reaction is favoured

b) the forward reaction is favoured

c) the forward reaction is favoured

Explanation:

The equation ought to have been correctly written as;

3A + 2B --------> C + 2D. ∆H =20 kJ

Actually, we can see that the reaction is endothermic since ∆H= positive.

We know that when pressure is decreased, the reaction tends towards the side with higher total volumes. There are five volumes(moles) of reactants and three volumes(moles) of products. A decrease in pressure will favour the reverse reaction.

Being an endothermic reaction, increase in temperature is known to favour the forward reaction. Similarly, removing D will drive the equilibrium forward thereby favouring the forward reaction.

Mi One should know the properties of the components of the mixture to separate it. Explain with an example.

Alekssandra [29.7K]

One should know that the properties of the components of the mixture.
Suppose a mixture contains Sodium or potassium .If you put them in open air it may catch fire.
Suppose a mixture has flammable components like kerosene,spirit .If you put them in fire it may harm you .

eleanor wants to show her class a comparison of melting rates between two different solids when he is applied why would a graph

sashaice [31]

Eleanor wants to show her class a comparison of melting rates between two different solids when heat is applied. A graph would be more suitable than a table to show her data because the she can see the trend line of the effects of melting than the table.
