100ml of 0.400 m AgNO3 and 90.0 ml of 0.250 m CaCl2 would combine to create 0.0225 moles of AgCl(s).
AgNO3 + CaCl2 -> AgCl + Ca(NO3)2 is the result of the given reaction
One mole of AgNO3 interacts with one mole of CaCl2 to produce one mole of AgCl in this reaction.
Given that AgNO3 (v1) has a volume of= 100 ml
Volume of CaCl2(v2) = 90ml
molarity of AgNO3 (m1) = 0.400M
Molarity of CaCl2 (m2) = 0.250M
Moles of AgNO3 formed: v1 x m1/1L = 0.1 x 0.4/1 = 0.04
moles of CaCl2 formed: v2 x m2/1L = 0.09 x 0.25/1L = 0.0225
Since AgNO3 exceeds 0.0225 moles of AgCl, CaCl2 is the limiting reactant in this limiting reactant problem.

a concentration cell is set up using two zinc wires and two solution, one containing 0.350 m zncl2 solution and the other containing 1.40 m zn(no3)2 solution. compute the potential of this cell.
Two zinc wires are used to create a concentration cell, and two solutions—one containing 0.350 m ZnCl2 solution and the other 1.40 m Zn(NO3)2 solution—are used to create the cell with potential 0f 0.0178V
Given that Zn(NO3)2 solution = 1.40m and ZnCl2 solution = 0.350m
According to the reading given above, the response was:
Zn ==> Zn2+(0.350 M) oxidation on the left side of Zn | Zn2+(0.350 M) || Zn2+(1.40 M)
Zn2+(1.40M) + 2e- translates into a reduction of Zn(s) on the right side.
Zn2+(1.40M) ==> Zn2+ then (0.350M)
The formula is as follows:
Ecell = Eocell - RT ln Q, where Q = 0.350 / 1.40 = 0.25 and the temperature is assumed to be 25oC (298K),
gives us Ecell = Eocell - 0.0592 / 2 log Q and
Ecell = 0 - 0.0296 log 0.25
Ecell = -0.0296 * -0.602 = 0.0178V

What is the difference between the collision theory and the transition state theory? How do they explain the factors that affect the rate of a chemical reaction?
The basic differences between the collision theory and the transition state theory are-
Collision theory assumes a collision between reactants needs to happen before a reaction can take place. But on the other hand, during a reaction, an increase in potential energy corresponds to an energy barrier over which the reactant molecules must pass if the reaction is to proceed.The majority of collisions do not lead to a reaction, but only those in which the colliding species have: kinetic energy greater than a certain minimum called the activation energy, Ea, and the correct special orientation with respect to each other. Whereas the transition state occurs at the maximum of this energy barrier.Collision theory states that chemical reactions (in the gas phase) occur due to collisions between reactants. But transition state theory states that chemical reactions occur via going through a transition state.According to collision theory, chemical reactions occur only due to successful collisions. Although according to transition state theory, a chemical reaction will happen if and only if the reactants can overcome the activation energy barrier.The factors that affect the rate of a chemical reaction:
Temperature: With increasing temperature reaction rate will also increase.Concentration: In a solution, if the amount of reactants increases then the reaction rate increases.Pressure: Increasing pressure increases reaction rate.State of matter: Gases react more readily than liquids, whereas liquids react more readily than solids.Catalysts: A catalyst lowers the activation energy, then the reaction rate increases.Mixing: Mixing reactants improves reaction rate.To learn more about this topic,

A covalent bond would form because the electron would be shared, so both hydrogen's have a full and stable shell.
What is covalent bond?The exchange of one or more pairs of electrons between two atoms forms a covalent connection. The two atomic nuclei are concurrently drawing these electrons to them. When the difference between the electronegativities of two atoms is too tiny for an electron transfer to take place to create ions, a covalent bond is formed.
Covalent bonds were first described in 1939. The word "covalent bond" is derived from the prefix co-, which means jointly, associated in action, partnered to a lesser extent, etc. The hydrogen atoms share the two electrons through covalent bonding since the prefix co- implies jointly, associated in action, etc.
Given element is hydrogen.
Although the element hydrogen is placed along with the alkali metals in group 1, the hydrogen atom act as a non-metal.
Hence to complete its valence shell, it shares 1 electron with another hydrogen atom and forms a covalent bond.
