Answer:

Explanation:

The state symbols been referred to in the question are s,l,aq and g.

s stands for solid

l stands for liquid

aq stands for aqueous

g stands for gas

The major reason this symbols are used is to signify the state of the molecules involved in the reaction. This is because the state of a substance sometimes shows the type of a product that will be formed and some other times, a substance in a particular state might have a certain property (required for a reaction) and in some other state would not have the same property. Hence it helps in understanding a reaction better. The following example should assist in understanding better

ZnS04(aq) + Cu(s) → CuSO4(aq) + Zn(s)

The reaction above shows ZnSO4 to be aqueous in the reactant but ZnSO4 could also be solid, however, for this reaction to occur, the compound must be in it's aqueous form. This product been solid zinc also shows that the reaction is an electrolytic equation as zinc (Zn) has been displaced by copper (Cu) from the solution. This reaction will typically not proceed also if the ZnSO4 used is solid.

Dr. Patel and her team have been using GPS to track two plates that are moving toward each

Andru [333]

C: One plate is going underneath the other plate and sinking into the soft rock below.

Explanation:

Where plates are moving towards each other they are said to converging, and are called convergent margins.

The lithosphere is broken into series of slabs called plates. The plates moves on the weak and relatively soft asthenosphere below.

Plates have different motion. At some places, they move apart and they are said to be divergent.

When plates moves towards each other, they are convergent. At a convergent margin, a plate collides with another thereby causing the denser plate usually the oceanic plate to subduct into the asthenosphere. In some other cases, the plates can collide and build upward.

CO2(g) + H2O(I) - -> C6H12O6(s) + O2(g)

Lana71 [14]

Answer:

For instance equation C6H5C2H5 + O2 = C6H5OH + CO2 + H2O will not be balanced, but PhC2H5 + O2 = PhOH + CO2 + H2O will; Compound states [like (s) (aq) or (g)] are not required. If you do not know what products are enter reagents only and click 'Balance'. In many cases a complete equation will be suggested.

CH3CO2H(aq) + H2O(l) ⇄ CH3CO2-(aq) + H3O+(l)

Evgen [1.6K]

Correct Answer: Option C: The equilibrium position will shift to the right toward the products.

Reason:
1) This problem is based on Le Chatelier's principle. It is stated as 'any changes in the temperature, volume, or concentration of a system will result in predictable and opposing changes in the system in order minimize this change and achieve a new equilibrium state.'

2) In present case, the reaction involved is:
 CH3CO2H(aq) + H2O(l) ⇄ CH3CO2-(aq) + H3O+(l)
Hence, when the concentration of acetic acid (reactant) is increased, the equilibrium will shift to right to minimize the effect of change in concentration of reactant.
